These are areas in the establishment where detectors are not necessarily required. ♦ Toilet and or bathroom with a floor area of less than 4 square meter. ♦ Exhaust ducts exhausting from toilets and or bathrooms. ♦ Any walk-in type enclosure with a floor area not more than 1 square meter provided its content is of minimal fire risk, or one with floor area not more than 0.5 square meter if it contains electrical or communication equipment. ♦ The spaces under raised floor with a height of 250 mm or less. ♦ The spaces above drop ceiling with a height of 1 meter or less without combustible materials. ♦ Concealed spaces under the roof with a height of 1 meter or less without combustible materials. ♦ Covered paths, balconies, open-sided covered walkways and staircases, overhanging roof areas, verandas, provided they are not used for storage of goods. ♦ The area under structures  such as platforms, ducts, and the like, within a protected  room or areas, which are less than 3 meters i...

FDAS | Areas where detection is required

Image
  These are areas or spaces where detection is required. ♦ The spaces under raised floor more than 600mm in height. If conventional detection are used, they should be wired as a separate alarm zone. ♦ The spaces above drop ceiling more than 1 meter in height. If conventional detection are used, they should be wired as a separate alarm zone. ♦ Concealed spaces under the roof more than 1 meter in height. If conventional detectors are used, they should be wired as a separate alarm zone. ♦ Stairwells, with detection at each floor level. ♦ Return air ducts of air conditioning system using sampling tubes. ♦ Tunnels linking two or more buildings. ♦ Vaults or the like. ♦ Vertical shafts. In places of assembly, the stage and enclosed platform used in occupancy. The Enclosed Platform , is a partially enclosed portion of an assembly room the ceiling of which is not more than one hundred fifty five centimeters (155cm) above the proscenium opening of which is designed or used for the presentati...

FDAS | General Requirements II

Image
  The Fire Detection and Alarm System SHALL comply with the installation requirements specified on Philippine Electronics Code Book II (Chapter 3). The properly designed, installed, and accepted Fire Detection and Alarm System SHALL undergo an annual testing and inspection by the authority having jurisdiction (AHJ) for reacceptance (refer to PEC II Chapter 4). The primary power supplied to the fire alarm control panel, and to the entire system, SHALL be from a DEDICATED and EXCLUSIVE branch circuit. The secondary power supply SHALL have sufficient capacity to operate the system under normal non-alarm condition for a minimum of 24 hours, and at the end of that period, capable of operating all alarm notification appliances and emergency communications system for a period of 30 minutes. Detectors, manual fire alarm stations, notifications appliances, emergency communications devices, and annunciators SHALL be installed throughout all parts of the building, facility, structure, or hous...

FDAS | General Requirements I

Image
    All buildings, facilities, houses, structures, and premises, except those specified here, SHALL have a Fire Detection and Alarm System that complies with the requirements of the Philippine Electronics Code book II (Fire Detection and Alarm System), and also provision of RA 9514. The Fire Detection and Alarm System SHALL be for the protection of life or property, or both, by detecting and notifying the existence of fire, smoke, heat, or other emergencies that impact and affect the protected premises. The Fire Detection and Alarm System SHALL have one or more of the following functions, specified below. ♦ Automatic detection of smoke and/or heat, and manual fire alarm signal initiation. ♦ Activation of fire alarm notification appliances. ♦ Emergency communications system. ♦ Activation of annunciators. ♦ Monitoring of abnormal conditions in fire suppression system. ♦ Activation of fire safety functions. ♦ Transmission of alarm signal to an off-premise Central Station. The Fir...

  The Power supply is the source of electricity that provides the power needed to operate the Fire Alarm Control Panel and including all devices connected to it. A fire alarm system serves many functions and the differences between the functions can be a bit confusing, so I created a visual guide to fire alarm basics. A fire alarm system is an important part of the overall fire protection and life safety of a building. Primary Power This is the 220Vac power supply voltage from the electrical utility company. Inside the Fire Alarm Control Panel it is then converted to the system voltage of 24Vdc. An engine-driven generator (this is not a standby generator, or a site generator meeting the requirements in NFPA 72), and Stored-Energy Emergency Power Supply System (SEPSS), or a co-generation system. Secondary Power In case of power failure of the primary power supply, the batteries (serving as the secondary power supply) automatically switch over to provide uninterrupted power to th...

The Difference Between Addressable and Conventional Fire Alarm Systems

Photo Credits | Georg Pik In both residential and commercial settings, fire alarm systems serve as indispensable tools for detecting and promptly notifying individuals of fire emergencies. Given the hazard fires present to life and property, it is essential to choose an appropriate fire alarm system to ensure the safety of our business. Selecting the right system will ultimately depend on the fire safety needs of your home or business, as well as your budget.   Fire alarm systems are essential for the early detection and notification of fire emergencies. Two common types of fire alarm systems used in residential and commercial buildings are conventional and addressable fire alarms.    Conventional Fire Alarms They consist of multiple fire detectors and devices connected to a central control panel. The detectors are divided into zones , and each zone is associated with a specific area or floor of the building. When a fire is detected in a particular zone, the corr...

Can we choose not to install a smoke detectors in buildings?

  Battery-Operated Smoke Detector As written in National Fire Protection Association (NFPA) section on the use of battery-operated smoke detectors. state that  buildings, structures, facilities, houses, or premises that are not record and refer of fire protection code, more than 400 sq. m. in total floor area, not more than two floor or levels, and with a height of not more than 10 meters may choose not to install a fire detection and alarm system. But it further add, however, in its place, battery-operated , stand-alone detectors shall be installed. Each battery-operated, stand-alone detector shall cover a floor area of not more than 50 sq.m.  Each room shall be separately protected. NFPA suggests incorporating battery-operated smoke detectors into a fire detection and alarm system in these areas. These detectors are crucial for alerting occupants to a fire early on, enabling safe evacuation and reducing property damage.  Battery-operated smoke detectors are simple ...
