    The alarm sound from audible notification appliances shall b e clearly audible throughout the floor and / or  building in which they are installed. It should be sufficient to warn and initiate evacuation of all occupants for whom the alarm sound is intended. A sufficient number of audible notifications appliances shall be used to produce a minimum sound level of 65 dBA, or 10 dB above the ambient noise level having a duration of at least 30 seconds, whichever is greater, measured 1.4 meters above the floor in the area required to be served by the system. The sound level produced by audible notification appliances and the ambient noise combined shall not exceed 115 dBA. If the sound level required is higher than 115 dBA, visual notification appliances such as strobes shall be used in addition to the audible notification appliances generating the maximum allowable sound level. In bars, nightclubs, and other entertainment places where the ambient noise level is high, the...

  Each building shall have at least one fire alarm control panel (FACP). However, two or more panels networked together shall be required in the following setting below. ♦ If the number of buildings in a multi-building complex exceeds three, or; ♦ If the total floor area of all the buildings in a multi-building  complex exceeds 40,000 square meters. For each panel in the network shall protect approximately the same floor area.   In a network of panels, there shall be at least one network display that shows the alarms and troubles of all panels in the network. The network display shall also be able to acknowledge, silence, and reset all alarms and trouble alerts. Location and Environments The fire alarm control panel or network display shall be located in the fire command center of the building or complex. In the absence of a fire command center, it should be located ideally in a position clearly visible from the main entrance of a lobby. However, if it is located in anoth...

    The general purpose of a Fire Detection and Alarm System is to detect at the earliest  stage of a fire, and to give a announce via an alarm to alert the occupants so that appropriate action can be decided. The alert display within the FDAS shall also be notified  so that an appropriate action and maintenance can be initiated to keep the system in normal operating condition at all times. All the individual components of an Fire Detection and Alarm System shall be compatible with each other. Suggest to have one brand for a system. All system equipment shall be approved and listed by institutions  recognized by the relevant authority, and suitable for use in the Philippines, considering ambient conditions such as temperature and relative humidity, and electricity supply of 220 Vac at 60 Hz. If any equipment is located in an area where it is exposed to corrosion, high humidity, extreme temperature or other special condition, the design and installation shall be ...

  Photo Credits | Macrovector   If necessary all installed Fire Detection and Alarm System should subscribe to the alarm monitoring services of a central station. All alarm signals received by the monitoring central station shall be forwarded or redirected to the nearby fire fighting authorities. The competence of the operators of the central station shall be certified by the manufacturer of the receiving system of equipment, or by an organization acceptable to the authority having jurisdiction (AHJ). Central station monitoring services are the best way to maintain peace of mind and keep your establishment secured 24 hours a day, 7 days a week. Central station alarm monitoring connects your alarm systems to an Underwriters Laboratory (U.L.) listed Central Station which is expected to respond any time an alarm is triggered. The central station will then notify the appropriate authorities of the incident so that help comes quickly. This can be very important if no one is on the ...

I have a presentation to electronics engineering students in Iligan Institute of Technology – Mindanao State University, the title “ Fire Detection and Alarm System” or FDAS. Safety is a common word we hear in industries but some of the world seems to ignore this and the obvious reason was that the city enforcement of laws are weak. The goal was to spread the awareness on RA9292, the electronics engineering law inclusion to the National Building Code which is crucial to protect building occupants from harm and prevent damage to property. There are 3 important phases of fire detection and alarm system; the time element, notification (manual and automatic alarm) and activation. The idea of FDAS was to sense signs of fire and alert personnel to prevent fire from getting bigger. Why do we need FDAS when we already have some fire extinguisher?  To answer that question lets discuss the fire department response time. First the ignition where combustion starts and fire grows undete...

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...

  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...
