Why we use Fire Alarm:
Not All Fires are the same: fires vary in their progression and spreading velocity. These depend on both the ambient conditions and the composition of the burning material. Fires are detected based on various factors: smoke, heat or gas. Customers can make the right choice for the detector intended use.
A fire alarm system is usually part of a total security and safety system. Several studies have concluded that when working smoke alarms are present, the chance of dying from the fire is cut in half.
A fire alarm system is an active fire protection system that detects fire or the effects of fire. In so doing, it provides one or more of the following services: it notifies the occupants, notifies persons in the surrounding area, summons the fire service, and controls all the fire alarm components in a building.
Traditional ways of Fire Alarm:
Conventional systems are set with a certain number of zones that are hardwired to the control panel or zone expander. Smoke detectors must be run on a separate zone from pull stations, etc. There may be a dozen detectors on a single zone and if one is faulty, the technician is tasked with finding which one. More cable is required because instead of having multiple device types wired to the same loop, a separate cable run for each type of device is required for these conventional systems.
Advanced ways of Fire Alarm:
Addressable Systems:
This type of installation provides state of the art emergency protection & is highly intelligent. It locates where exactly the source of smoke or trigger or fire.
Advantages of Addressable systems:
The main advantage of this system is for protection of large buildings because If a detector is triggered it provides a text read out of exactly where this unit is e.g. “smoke detector 17 managers office”. Whereas a detector on a conventional zone may take some time to find.
Addressable systems are used in Hotels & Hospitals, large factories & warehouses, schools & colleges, nursing homes, complex offices & multifunctional buildings. As well as giving an exact point of trigger various other options are available including; Sounders on the same circuit, cause & effect programming, intelligent control of other equipment, phased evacuation.
Wireless Systems:
When installation costs are taken into account, radio alarm systems offer very cost effective fire protection and have distinct advantages over the traditional wired installation.
