Transcript: Fire Alarm Systems By Jake Caughell Why we need Fire Alarm Systems A Fire Alarm systems main purpose is to identify a developing fire emergency as fast as possible, and to alert the building's occupants and local fire department. Today you have about three or four minutes to escape a house fire. This is mainly due to newer homes and buildings have furniture and combustible material inside them that burn faster. In less than 30 seconds a small flame can turn into a major fire. It only takes minutes for thick black smoke to fill a house or for it to be engulfed in flames. Why we need Fire Alarm Systems Fire is a chemical reaction between oxygen in the air and some kind of fuel. For a fire to take place, you have to heat up the fuel to a high enough temperature for it to ignite. In every building there is many combustible material that can fuel a fire. How fires start How fires start The types and parts of Fire Alarm Systems There are two main types of Fire Alarm Systems: Addressable and Conventional. Conventional fire alarms include a number of different zones that are connected to your central control panel. Addressable fire alarms are also called intelligent systems as they monitor the fire alarms in your building. Each alarm has its own address which allows you tell which ones are working. The types and parts of Fire Alarm Systems #1 Components - Fire alarm control panel (FACP) - Initiating devices - Power supply - Notification appliances #2 Devices - Manual pull stations/manual call points - Smoke detectors - Water flow switches - Rate-of-Rise and heat detectors - Valve supervisory switch - Carbon monoxide detector - Notification appliances - Magnetic door holder Passive and Active Fire Protection The buildings fire and life safety components are reffered to as either passive or active features. Passive and Active Fire Protection - Roof construction types - Fire rated walls - Fire rated floors and ceilings - Fire rated doors - Interior finishes - Smoke/Fire dampers - Means of egress - Fire stops Passive Passive - Sprinkler systems - Standpipes - Detection and alarm systems - Smoke controlled systems - Building configuration - Special hazard systems - Elavator controls - Vegatation management Active Active Ontario Building Code references In Ontario there is only one building code that is universal throughout the province for both large and small municipals 3.2.4.5. installation and Verification of Fire Alarm Systems (1) Fire alarm systems, including those with voice communication capability, shall be installed in conformance with CAN/ulc-S524, "installation of Fire Alarm Systems". (2) A fire alarm system shall be verified in conformance with CAN/ulc-S537, "Verification of Fire Alarm Systems", to ensure satisfactory operation.
