Study Notes
Fire Detection and Alarm Systems (FDAS)
- A properly designed, installed, and accepted FDAS shall undergo annual testing and inspection by the Authority Having Jurisdiction (AHJ) for reacceptance.
- AHJ refers to the Office of the Building Official (OBO) or the Bureau of Fire Protection.
Alarm Zones
- An alarm zone shall have a maximum floor area of 800 sq.m.
- A separate alarm zone shall be provided for each 800 sq.m. of protected floor area.
Audible Notification Signal
- Shall have a sound level of at least 15 dB above the average ambient sound level, or 5 dB above the maximum sound level having a duration of at least 30 seconds or 75 dBA, whichever is greater, measured 1.40 meters above the floor in the area required to be served.
Maintenance and Monitoring Tests
- Daily, Weekly, Monthly, and Annually tests shall be conducted.
CCTV Cameras
- Can be organized into 4 major types: Bank Style, Color Day/Night, Bullet Cameras, and Miniature & Hidden Cameras.
- Bank Style cameras are rectangular and can be used indoors or outdoors with camera housing.
- Color Day/Night cameras are used for outdoor applications and switch to B/W at night using infrared illuminators.
- Bullet Cameras are general-purpose cameras with built-in weatherproof housing.
- Miniature & Hidden Cameras are mainly for indoor use and disguised in ordinary items.
Camera Specifications
- Lux rating measures available light, with examples:
- Direct sunlight: 100,000 - 130,000 Lux
- Overcast day: 1,000 Lux
- Deep twilight: 1 Lux
- Full moon: 0.1 Lux
- Quarter moon: 0.01 Lux
- Color cameras need more light to work than B/W cameras.
CCTV Lenses
- Fixed focus, manual iris lens, vari-focal, DC auto iris, and zoom lens are available.
- C-mount and CS-mount lenses are the two categories.
Monitor Placement
- Install outside security cameras, considering the sun's rise and set, to avoid glare on the lens.
Monitors and DVRs
- CCTV monitors can provide up to 1000 lines of resolution, compared to 300 lines on a TV.
- Digital Video Recorders (DVRs) combine the reliability of time-lapse recorders with advanced features like motion detection recording and remote viewing.
- PC-based DVRs offer the most features but require an enormous amount of processing power, memory, and operating system resources.
- Standalone DVRs offer many of the same features at a lower cost.
Power Supplies
- Individual transformers or a power distribution panel can power the camera system.
- A power strip with 8 outlets is recommended for neater installations, especially for systems with more than 4 cameras.
Recording Devices
- Time-lapse VCRs are reliable but have limitations in recording resolution and motion fluidity.
- Digital Video Recorders (DVRs) are a better option for long-term recording.
- The amount of hours a standard VCR can record is dictated by the size of the tape used.
Fire Detection and Alarm Systems (FDAS) Components
- Fire alarm control panel
- Display panel
- Annunciator
- Smoke detector
- Heat detector
- Manual pull horn
- Strobe
Importance of Fire Detection and Alarm Systems
- Critical components of any building's safety infrastructure
- Legal requirements and building codes include:
- RA9292 – Electronics Engineering Law
- RA 9514 Fire Code
- DPWH Department Order 231 series 2016
- National Fire Protection Association
- Philippine Integrated Fire Protection Organization
