This equipment may contain Electrostatic Discharge Sensitive (ESDS) devices. Equipment handling methods and materials must be used to prevent equipment damage. Refer to Air Force Technical Order 00-25-234, Section VII, before disassembly, repair and assembly is performed for safety precautions. The requirements for marking assemblies, sub-assemblies and parts are governed by MIL STD 1686A, DOD HDBK 263, MIL STD 1285A and MIL STD 129. Either of the following symbols may be used to identify ESDS devices that require special handling precautions to prevent damage to the equipment. Electrostatic Discharge (ESD) can cause immediate or latent damage to electronic circuits. Vaisala products are adequately protected against ESD for their intended use. However, it is possible to damage the product by delivering electrostatic discharges when touching, removing, or inserting any objects inside the equipment housing. To make sure you are not delivering high static voltages yourself: - Handle ESD sensitive components on a properly grounded and protected ESD workbench. When this is not possible, ground yourself to the equipment chassis before touching the boards. Ground yourself with a wrist strap and a resistive connection cord. When neither of the above is possible, touch a conductive part of the equipment chassis with your other hand before touching the boards. - Always hold the boards by the edges and avoid touching the component contacts. 1-3 T.O. 31M1-2TMQ53-1 1.1.2.4 Safety Precautions.

Warnings applicable to hazardous materials are based on information contained in the MSDS. The Material Safety Data Sheets are included in their entirety in Appendix A. 1.1.5 TIME COMPLIANCE NETWORK ORDER (TCNO). Network security is a primary concern for Air Force organizations utilizing computer technology. Network software vulnerability patching is a critical determinant of network security. The Air Force deploys these patches in response to Time Compliance Network Orders (TCNOs) issued by the Air Force Network Operations and Security Center (AFNOSC) or Network Operations and Security Center (NOSC) as directed by Air Force Instruction AFI33-138. The AFNOSC or NOSCs will generate TCNOs in response to an Information Assurance Vulnerability Alert (IAVA) to direct the implementation of an operational or security vulnerability risk mitigation procedure or fix action (i.e., software patch). The Raytheon Tactical Weather Help Desk evaluates the TCNOs for applicability to the TMOS and reports back to the program management office to ensure timely TCNO accountability. Raytheon will test each applicable TCNO patch to ensure no detrimental impacts to the TMOS operations. Periodic computer restoration loads will be built with installed patches and will be distributed to all TMOS users as a system restoration DVD. Users will be required to load the new update to fulfill TCNO compliance. 1.1.6 DEFICIENCY REPORTING PROCEDURES.

Block 4 - TODO TYPE Select the appropriate block(s) and enter corresponding information as applicable. NOTE A Government-Owned, Contractor-Operated (GOCO) TODO TM Account has a government ship-to address, and is established for direct support of a day-to-day government mission/activity. The TOs are required to support the government mission and are independent of the contract. The TM Account is established and managed on a government installation computer network (forms and orders submitted from a “.mil” or “.gov” domain). These TODOs are considered government TODOs (TM account code F*xxxx) and are allowed to FTP TO Publication Requests directly to the Tinker gateway. Upon contract termination, the TODO account will return to the AF or transfer to a new contractor who will perform the service. A contractor TODO TM Account is established for direct support of the contractor mission and organization, and has a commercial ship-to address. The organizational need for TOs is dependent upon the performance and/or delivery of government contract tasks, and will lapse when the contract expires. The TM Account is generally established and managed on a non-government computer network (“.com” or “.org” domain). These TODOs are contractor TODOs (TM account code E*xxxx), and TO Publication Requests must be submitted through the GAA identified in Block 7 of the AFTO Form 43. 1-12  T.O. 31M1-2TMQ53-1 Table 1-3. Instructions for Completing AFTO Form 43 (Continued) Blocks 4a, 4b, 4c, and 4d Government TODOs, including GOCO TODOs, will select one block (only) to indicate whether the function will be a Standard TODO, Nuclear Weapon TODO, Nuclear Related EOD TODO or a Non-nuclear EOD TODO.

This section will provide the user with the information for packaging the TMOS equipment with the additional equipment. 1.2.2 CLEANING EQUIPMENT PRIOR TO SHIPMENT/STORAGE. Loss of equipment components will impair or make mission objectives impossible. It is essential that all care be given to properly maintain, store, and inventory the components that comprise the TMOS Weather Station. 1.2.2.1 Packing and Storing Equipment for Deployment. Check all cables and connectors to see if they might be damaged, frayed, or cracked. Check all connector caps to ensure they are watertight. Clean all connectors by using light oil or WD-40 and air-dry to keep the quick snap connectors in good operating condition. Wipe the cables down with a light detergent (i.e., dishwashing soap) to remove all dirt and grease. This will help keep the cables flexible. 1.2.2.2 Ceilometer (CT25KAM / RA-TM-EN-LBC-01). Never look directly into the Laser. Only trained personnel should perform maintenance functions. No user serviceable parts are installed. Prior to cleaning the CT25KAM (RA-TM-EN-LBC-01) ceilometer, disconnect the power source to turn off the laser. The ceilometer lens and blowers will need to be cleaned. Failure to clean the lens may cause pitting over time. The Raytheon Tactical Weather Help Desk recommends mild detergent solution (one part non-phosphate dishwashing liquid to twenty parts warm water) and rinse with warm water to clean the lens. The blowers located at the top of the ceilometer will need to be examined for debris that might stop the fan blades from turning. 1.2.2.3 Present Weather Detector (PWD11A / PWD22M (RA-TM-EN-PWD-01 / RA-TM-EN-PWD-02)). Never look directly into the Laser. Only trained personnel should perform maintenance functions. No user serviceable parts are installed. Prior to cleaning the PWD11A (RA-TM-EN-PWD-01) or PWD22M (RA-TM-EN-PWD-02), Present Weather Detector (PWD), disconnect the power source to turn off the laser. To clean the PWD11A / PWD22M (RA-TM- EN-PWD-01 / RA-TM-EN-PWD-02) ensure that the lenses are cleaned like the ceilometer lens. The special part on this unit is the Direct Reading Dosimeter (DRD) Precipitation Detector on top of the PWD. Clean the DRD as follows. 1-15 T.O. 31M1-2TMQ53-1 The measuring principle does not allow for proper ESD protection of the DRD electronics, so the following step must be performed to prevent damage to equipment. Ground your hand first by touching grounded metallic parts of the installation to remove excessive static charges from your body. To prevent damage to the equipment, do not touch the DRD with bare fingers which could leave fingerprints and oil and do not wipe the DRD with a dry cloth which could create scratches. Clean the DRD rain detector carefully with a soft lint-free cloth moistened with water only. Be careful not to scratch the surface. Check that the detector is free of ice and snow deposits. 1.2.2.4 Power Supply Enhancement (QMP202 / RA-TM-EN-PWR-01). Prior to storage or shipment of the QMP202 (RA-TM-EN-PWR-01), Power Supply Enhancement, check all seals for damage. The main seal around the top and the two seals around the screw downs will deteriorate over time. If seals are cracked, return the QMP202 (RA-TM-EN-PWR-01) to Raytheon for a replacement. The QMP202 (RA-TM-EN-PWR-01) can be cleaned with the rest of your TMOS as stated in the next paragraph. 1.2.2.5 System Cleaning. Do not place the bleach solution over the ceilometer lens, PWD lenses, or the DRD, as this will damage these parts. For moderate cleaning, clean the TMOS exterior with a mild detergent solution and soft cloth. If, however, your equipment has been out in the field for weeks or months, then a heavier cleaning is recommended. This can be accomplished by using bleach and water solution (recommend 1 part bleach to 10 parts water), rubber gloves and respirator if necessary. The bleach solution will disinfect equipment from bird or animal droppings, insects, and any other contaminant that might have collected on your TMOS which could cause a health hazard to personnel. 1-16  T.O. 31M1-2TMQ53-1 1.2.3 SHIPPING PARTS TO RAYTHEON. Problems or issues involving the TMOS should be logged with the Air Force Weather Agency Customer Service Center (AFWA CSC) and with the Raytheon Tactical Weather Help Desk. A Raytheon Tactical Weather Help Desk Technician will be able to provide additional troubleshooting procedures or solutions that the customer can implement or check. Also, there can be a component or part on the TMOS that is broken and creating a false error message indicated on the Handheld Display or laptop computer. Failure to work with one of our Technicians may lead to an incorrect part being replaced and cause a longer than necessary downtime for the system. When a problem or issue cannot be fixed over the phone or through email correspondence, contact the Raytheon Tactical Weather Help Desk and arrange the shipment of a replacement part for the TMOS as soon as possible. The Raytheon Tactical Weather Help Desk Technician will request the serial number of the broken part (when applicable) and send a return-shipping document, ensuring that no out of pocket expenses are incurred for the shipment of the unit. Prior to shipment, the customer will need to provide the Raytheon Tactical Weather Help Desk Technician with the failure, all warning or alarm messages noticed, or if it was physically damaged in some way (e.g., dropped, run over by a vehicle, knocked over by the wind, etc.) so the technician can start at a known failure point. Next, the customer will prepare the damaged part for shipping by cleaning and packaging in the container that was sent with the replacement part when possible. (Note: Raytheon can ship the customer a container for returning items as necessary.) Your local Transportation/Shipping Office can help with proper packaging. Figure 1-2 is a sample of poor packaging. Figure 1-2. Sample of Poor Packaging Both the Raytheon Tactical Weather Help Desk Technician and the customer must ensure all serial numbers are recorded on the shipping documents. This is especially necessary to track lost or misplaced shipments and for customs clearance regulations. 1.2.3.1 Health and Safety Concerns. Figure 1-3 depicts parts returned to Raytheon from different locations. The bird dropping on the QMP202 (RA- TM-EN-PWR-01) and PWD11A (RA-TM-EN-PWD-01) were very dangerous to whom-ever came in contact with them. The droppings from birds, animals, and even insects can make a person seriously ill and in some cases lead to death. The Airman, shipper, Customs Agents, receiver, or anyone else handling this was in danger from toxic poisoning due to the direct handling or the breathing in of dust produced when the equipment crate was opened. 1-17 T.O. 31M1-2TMQ53-1 Figure 1-3. Bird Droppings Rodents, insects, reptiles, and spiders have been found in the shipping crates by Raytheon Tactical Weather Help Desk technicians (see Figure 1-4). All storage and shipping containers need to be cleaned prior to use. Wipe down the inside of the container to ensure that all dirt and foreign objects are removed before shipping. Customs agents and USA Agriculture agents can confiscate any item that possesses a threat to the agriculture community. Once an agent confiscates the shipment a fine can be levied upon the shipper or receiver, as well as causing excessive delays in shipping a replacement part. Handle all equipment with care and think about safety. Figure 1-4. Lizard Found in a QMP202 (RA-TM-EN-PWR-01) 1-18  T.O. 31M1-2TMQ53-1 1.2.3.2 Import and Export of TMOS Equipment. The paperwork accompanying TMOS equipment leaving various countries is often incorrectly filled out and not correctly placed on the packing materials. Use the following steps as a guideline for the import and export of TMOS equipment. 1.2.3.2.1 Complete all Import and Export Documentation and Affix it to the Proper Location on TMOS Packaging Materials.

EQUIPMENT CHARACTERISTICS 1.3.1 CAPABILITIES AND PERFORMANCE CHARACTERISTICS/REQUIREMENTS. The TMOS is a Commercial Off The Shelf (COTS) weather-sensing device that is used to gather weather data for operational situations for both the Air Force and the Army. The system is remotely deployed and can provide weather data to a base station either by a 225-foot landline cable or via Radio Frequency (RF) communications for up to five (5) nautical miles. Data is displayed on a computer located at the base station using the Automated Observation System (AOS) software. The AOS software generates periodic Meteorological Aviation Report (METAR) and Special METAR (SPECI) reports and transmits the reports to the Weather Product Management Distribution System (WPMDS) server at the Air Force Weather Agency (AFWA). The reports are transmitted by File Transfer Protocol (FTP) either via the Iridium® Modem and the Iridium® Satellite Constellation (see Figure 1-10) or via Common User Communications (CUC) using the Non-Secure Internet Protocol Router Network (NIPRNET) (see Figure 1-11). Figure 1-10. METAR/SPECI Reporting Thru Iridium® Gateway FTP/NIPRNET Gateway Computer & AOS Client Figure 1-11. METAR/SPECI Reporting Thru CUC NIPRNET 1-29 T.O. 31M1-2TMQ53-1 1.3.1.1 Tactical Meteorological Observing System (TMOS). The main structure of the TMOS is a tripod that is staked into the ground for stability. Sensors provided with the system include a pressure sensor, a combined temperature and relative humidity sensor, and a combined wind speed and wind direction sensor. In addition, the system consists of a Central Processing Unit (CPU) (also called Automatic Weather Station (AWS) Logger), a power supply, a battery back-up, a solar panel for use when commercial power is not readily available, a handheld display for retrieving data or diagnostic use, two RF modems for sending RF signals, landline cables, ground pegs for staking the tripod into the ground, a base station laptop computer with a backup restoration DVD, a present weather/visibility sensor, a ceilometer, a lightning sensor, an enhancement power supply, and assorted interface cables. 1.3.2 EQUIPMENT DESCRIPTION. Figure 1-12 depicts the major TMOS components and lists their nomenclatures and part numbers. 1.3.2.1 Tripod (QML101T / RA-TM-BA-TPD-01). The tripod is the central structure supporting many of the sensors. All of the sensors hook into the tripod and it is used to perform all of the data calculations. The tripod contains the battery, solar panel, and the pressure sensors. 1.3.2.2 Sensor Arm (QMA102M / RA-TM-BA-ARM-01). 1.3.2.2.1 Rain Gauge (QMR101M). The QMR101M is a self-emptying, frostproof electronic rain gauge, which registers the precipitation at 0.2 mm resolution. It measures the amount of the precipitation by means of a 200 cm2 funnel that leads the water down into a self-emptying “spoon” held in place by a magnet. The magnet always exerts just enough tension to allow the measuring spoon to empty in one quick movement (less than 300 ms) and then return to its normal position, ready to collect rainwater again. The basic idea behind the QMR101M is that the measuring spoon in the rain collector automatically tips and empties, each time the spoon registers an amount of water which it is adjusted for, i.e. 0.2 mm. The rain collector consists of three parts: a 200 cm2 funnel, a box with a self-emptying “spoon”, and a base with grooves where the water runs out. The parts can easily be taken apart and assembled again without the use of tools. 1.3.2.2.2 Humidity and Temperature Probe (HMP45DX / RA-TM-BA-TMP-01). The HMP45DX (RA-TM-BA-TMP-01) is the humidity and temperature probe for the TMOS. The HMP45DX (RA- TM-BA-TMP-01) has a cable and molded connector specifically designed for the TMOS. The HMP45DX (RA-TM-BA-TMP-01) probe is designed for the measurement of relative humidity and temperature. Humidity measurement is based on the capacitive thin film polymer sensor HUMICAP®180. Temperature measurement is based on resistive platinum sensors (Pt 100 and Pt 1000). Both the humidity and temperature sensors are located at the tip of the probe and in standard version protected by a membrane filter. The HMP45DX (RA-TM-BA-TMP-01) temperature output is passive (resistive output Pt 100). 1-30  T.O. 31M1-2TMQ53-1 Figure 1-12.

TMOS Equipment (Sheet 2 of 2) 1-32  T.O. 31M1-2TMQ53-1 1.3.2.3 Wind Speed/Direction Sensor (WMS302M / RA-TM-BA-WND-01). The WMS302M (RA-TM-BA-WND-01) is a compact sized instrument with the wind speed and direction sensors integrated into one unit. The sensor electronics are located inside a watertight compartment providing full protection against water, dust, pollutants, and electromagnetic interference. The cup wheel shape, dimensions, and material have been carefully designed to achieve maximum measurement quality. The conical cups have been tested to give linear response between wind speed and angular velocity of the cup wheel. The polyamide plastic reinforced with carbon fiber guarantees a rigid structure even at the highest wind speeds. The anemometer ball bearing assembly is composed of a wheel shaft, a pair of low friction ball bearings, and a shaft fixed magnet. A reed relay with electronics located in the body of the sensor converts the cup wheel rotation to pulses. The sensor counts the number of pulses within a fixed time period or measures the time between successive transients. In the later method averaging of transient intervals should be used, since two pulses with non-symmetric positioning are generated during one revolution. The balanced wind vane is integrated in the housing, underneath the cup wheel. The circular tail is located far enough from the body and the cup wheel to avoid turbulence due to these structures. The vane assembly is made of PA reinforced with glass fiber providing durable and lightweight structure with fast response and low inertia. The angular position of the vane is detected using an axial symmetric rotating potentiometer. The potentiometer features low starting and running torque, linear arc-to-resistance transfer ratio, and long operational life. 1.3.2.4 Ceilometer (CT25KAM / RA-TM-EN-LBC-01). The CT25KAM (RA-TM-EN-LBC-01) ceilometer is used to measure cloud heights and vertical visibilities. The small and lightweight measurement unit suits well for mobile operation. The CT25KAM (RA-TM-EN-LBC-01) ceilometer employs pulsed diode laser Light Detection and Ranging (LIDAR) technology where short, powerful laser pulses are sent out in a vertical or near-vertical direction. The reflection of light – backscatter – caused by haze, fog, mist, virga, precipitation, and clouds is measured as the laser pulses traverse the sky. The resulting backscatter profile, i.e. signal strength versus height, is stored and processed and the cloud bases are detected. Knowing the speed of light, the delay between the launch of the laser pulse and the detection of the backscatter signal indicates the cloud base height. The CT25KAM (RA-TM-EN-LBC-01) ceilometer is able to detect three cloud layers simultaneously; additionally with the sky condition option up to four cloud layers can be measured. Besides cloud layers it detects whether there is precipitation or other obstructions to vision. No adjustments in the field are needed. The embedded software includes several service and maintenance functions and gives continuous status information from internal monitoring. The software is designed to give the full backscatter profile. 1.3.2.5 Present Weather Detector (PWD11A / PWD22M (RA-TM-EN-PWD-01 / RA-TM-EN-PWD-02)). The PWD11A / PWD22M (RA-TM-EN-PWD-01 / RA-TM-EN-PWD-02) PWD is an intelligent multi-variable sensor for automatic weather observing systems. The sensor combines the functions of a forward scatter visibility meter and a present weather sensor. In addition, the PWD11A / PWD22M (RA-TM-EN-PWD-01 / RA-TM-EN-PWD-02) can measure the intensity and amount of both liquid and solid precipitation. The PWD11A / PWD22M (RA-TM-EN-PWD-01 / RA-TM-EN-PWD-02) is suitable for weather observing systems providing valuable information to, for example, road and harbor authorities. The versatility of the PWD11A / PWD22M (RA-TM-EN-PWD-01 / RA-TM-EN-PWD-02) PWD is achieved with a unique operating principle. The PWD11A / PWD22M (RA-TM-EN-PWD-01 / RA-TM-EN-PWD-02) measures an estimate of the precipitation water content with a capacitive device and combines this information with optical scatter and temperature measurements. These three independent measurements together provide sufficient data for an accurate evaluation of prevailing visibility and weather type. 1-33 T.O. 31M1-2TMQ53-1 1.3.2.6 Lightning Detector (SA20M / RA-TM-EN-LTG-01). The SA20 StrikeAlertTM thunderstorm sensor detects the general position of the thunderstorm activity and reports both range and bearing with respect to the SA20 location. The stand-alone thunderstorm sensor is self-contained and weather-tight. The SA20 processes thunderstorm positions in real time based on lightning activity. It detects cloud-to-cloud and cloud-to-ground lightning activity at a range up to 40 Nm. The SA20 can be used as a portable system for organizations requiring mobile weather stations. It has a single power and data cable and three major components: an antenna with vertical electric-field and crossed-loop magnetic field detectors, an antenna ground plane, and a rugged weather-tight electronic housing which encloses the strike processor, main processor, and all system interfaces. 1.3.2.7 Laptop / Iridium Communications (400VTX (RA-TM-LT-CPU-02) / M405 (RA-TM-LT-CPU-03) / M250E (RA-TM-LT-CPU-04) / M255E (RA-TM-LT-CPU-05) / 8510p (RA-TM-LT-CPU-06)). The Iridium® communications includes a laptop computer, software, an Iridium® modem, a Subscriber Information Module (SIM) card, an Iridium® modem power supply with USB interface, an Iridium® antenna, an antenna tripod, and assorted interface cables. The operating system of the laptop associated with the TMOS is Windows 2000 with the following programs: AOS, Dial UP Signal Monitor, PDLCONF, and Af EasyStart. The programs listed are the ones directly used to interface with the TMOS or programming of RF modems. The individual programs will be discussed later in separate sections. The TMOS provides real-time weather data to the laptop using AOS software to generate Meteorological Aviation Report (METAR) and Special METAR (SPECI) observation and then transmits the observation via the Iridium® Modem to the Iridium® Satellite Constellation or a local area network. 1.3.2.8 RF Communications. 1.3.2.8.1 Pacific Crest RF Modem (RFM96W (RA-TM-UL-MDM-01 / RA-TM-UM-MDM-01 / RA-TM-UH-MDM-01)). The RFM96W Pacific Crest RF Modems will continue to be used but are being replaced through attrition with the new Af RF modems. The RFM96W modems will continue to be used to transmit data from the TMOS sensors and data logger to the laptop as needed by distance, where AOS software will convert the raw data into a weather observation for transmission. To program the RFM96W Pacific Crest RF Modems, the user will need to use Pacific Crest’s “PDLCONF” Program, Dealer Revision 4.00 (located on the laptop computer at C:\Program Files\PCC\PDLCONF4.0\Dealer\PDLCONF.exe), which can be selected using the “PDL” icon on the Desktop screen. While this software was designed to be able to use the USB-to-Serial Converter Cable, ZZ45202, ZZ45213, and the QMP211US, there are some minor problems that have been identified and will be discussed in a later section, with the overall use of the software. The RF modem connects to the TMOS via cable ZZ45212 and to the laptop (laptops manufactured today normally do not have a built-in serial port), requiring the users to connect the RF modem to the laptop via a USB- to-Serial Converter Cable, ZZ45202, ZZ45213, and the QMP211US. The USB-to-Serial Converter Cable should be used with COM 4 on the AOS laptop due to the “PDLCONF” Program being preset to use COM 4. 1-34  T.O. 31M1-2TMQ53-1 1.3.2.8.2 AF RF Modems (AW100Af / AW400Af (RA-TM-VH-MDM-02 / RA-TM-UH-MDM-02)). The Af RF modems are a form/fit/function replacement for the RFM96W (RA-TM-UL-MDM-01 / RA-TM-UM-MDM- 01 / RA-TM-UH-MDM-01) Pacific Crest RF modems. The operating frequency range of 138-174 MHz (VHF) and 410-470 MHz (UHF) supported by a family of 5 VHF/UHF RFM96W (RA-TM-UL-MDM-01 / RA-TM-UM-MDM-01 / RA-TM-UH-MDM-01) RF modems and associated antennas/cables is replaced by a family of a single VHF and UHF Af modem pair and associated antennas/cables. After the Af Modems are set up using the Af EasyStart configuration software, the function of the modems is completely transparent to the user and AOS software. The Af modems provide the remote distance interface between the TMOS sensors and data logger to the user station laptop, where the AOS software will convert the raw data into a weather observation for transmission to the WPMDS. To program the Af RF modems the user will use the Af Modem “Af EasyStart” Program, Version 1.0.0.1 (located on the laptop computer at C:\Program Files\AfEasyStart\AfEasyStart.exe), which can be selected using the “AfEasyStart” icon on the Desktop screen. The biggest difference to the user is the need for the CM-10008 Maintenance cable, the USB-to-Serial adapter, and the QMP211US to program the Af modem settings into the mode. The Af modems connect to the TMOS via cable CM-00212 and the laptop via cable CM-00213, ZZ45202, and the USB-to-Serial adapter. Additionally, the Af modem “Af EasyStart” Program, Version 1.0.0.1 (located on the laptop computer at C:\Program Files\AfEasyStart\AfEasyStart.exe) can read and program the Af modem settings into the modem through the USB-to-Serial conversion cable and CM-10008 maintenance cable. 1.3.2.9 Enhancement Power Supply (QMP202 / RA-TM-EN-PWR-01). The power supply module QMP202 (RA-TM-EN-PWR-01) is used for supplying the +12 V operating voltage for the TMOS sensors. It is composed of three submodules mounted into a weather resistant enclosure: a mains power supply, a battery regulator, and two 12 V, 24 Ah rechargeable batteries. The QMP202 (RA-TM-EN-PWR-01) accepts input from the mains power line with an input voltage range as large as 85 to 264 Vac. It has five separate output lines: DC and AC outputs for the CT25KAM (RA-TM-EN-LBC-01), and bare DC outputs for the PWD11A / PWD22M (RA-TM-EN-PWD-01 / RA-TM-EN-PWD-02), SA20M (RA-TM- EN-LTG-01), and TMOS. The AC output is only available when the mains supply voltage is on, whereas the DC outputs are supported by the integral batteries for providing uninterrupted operation during mains power breaks. Also included are LED lamps visible through a small window on the enclosure door for indicating Battery OK/Low and Charge/Recharge conditions. In order to maximize autonomy time, the lamps are activated only while the LED ON pushbutton is pressed. The QMP202 (RA-TM-EN-PWR-01) power supply module is a weather proof construction designed to be used in rugged conditions with installation straight on the ground surface. The connection and disconnection of the QMP202 (RA-TM-EN-PWR-01) from the mains supply and from the sensors are easy with plug-in connectors. 1.3.2.10 Auto-Restart Cable (ARC) (RA-TM-PW-ARC-01). The ARC, Raytheon part number RA-TM-PW-ARC-01, is a direct replacement for both the original TMOS QPS101 115V and the QPS103 230V Outdoor Power Strips. The ARC provides input power protection from under/overvoltage power surges, transient voltage/current spikes, and provides an auto-restarting capability when voltage returns to normal operating parameters. The QPS101/103, which this device replaces, required a manual reset by the operator resulting from an out of tolerance power input condition. The ARC will eliminate the manual resets by automatically disconnecting and restoring commercial power as necessary. 1-35 T.O. 31M1-2TMQ53-1 1.3.2.11 Cabling.
