Study Notes
Fire Detection and Alarm System (FDAS)
- FDAS provides early fire detection and alerts to protect lives and property.
- Critical for timely identification of fire emergencies and alerting occupants and emergency personnel.
- Part of active fire protection systems alongside automatic fire suppression systems.
- Applicable in commercial, residential, industrial, and institutional settings.
Addressable System
- Point capacity based on the number of SLC (Signaling Line Circuits) it includes.
- Each SLC powers and communicates with connected devices, supporting over 100 addressable devices based on manufacturer specifications.
- Each device on the SLC receives a unique address during installation.
- Capable of accommodating various addressable devices with non-addressable ones connected through modules.
Conventional System
- Control panels range from 1 to over 100 zones, with alarm conditions reported by zone only.
- Requires inspection to identify specific devices triggering an alarm.
- Zones are comprised of initiating devices from specific areas or floors.
- Limited expansion capability may hinder adaptation for additional buildings or rooms.
Intelligent System
- Detectors integrate computing capability to assess the environment and communicate with the control panel.
- Aimed at reducing false alarms and enhancing system responsiveness.
Output Devices
- Visual notifications are mandatory if sound levels exceed 105 dB, with a maximum limit of 120 dB.
- Types of output devices include bells, buzzers, horns, and strobe lights that signal alarms.
Input Devices
- Manual fire boxes should be installed 42-48 inches above the floor in visible locations.
- Must comply with NFA72 standards for installation.
CCTV Design Considerations
- Lighting conditions (natural and artificial) greatly influence camera system effectiveness.
- System design should address lighting strategies and camera locations to optimize performance.
- Scalability allows systems to expand with additional components.
- Cost evaluations should encompass the entire life cycle of the system, including installation, maintenance, and personnel expenses.
Basic Elements of Camera
- Image sensor converts light into electronic signals.
- Lens gathers and focuses light onto the image sensor.
- Image processing circuitry organizes and transmits video signals.
Camera Selection Criteria
- Desired image quality, field of view (FOV), and ambient light conditions are essential factors.
- Different types of cameras are suitable for various environments, including fixed cameras, thermal imaging, and miniature cameras.
Camera Mounting Options
- Wall mounts, pendant mounts, corner mounts, and indoor dome camera mounts serve various installation needs.
- Outdoor mounts include pole mounts for enhancing camera elevation and field view.
Switchers and Multiplexers
- Used for routing video signals when multiple cameras exceed monitor capacity.
- Switchers can be set manually or automatically to send video frames sequentially to recorders.
- Multiplexers record multiple frames simultaneously and improve system efficiency.
Wired Transmission
- Coaxial cable is the most common transmission method for video signals, composed of multiple layers for insulation and protection.
