Fire alarm systems <br>• A fire alarm system comprises of a main controller which provides power to the system and monitors the input through various circuits. <br>• The main controller is an interface which gets activated automatically in the event of fire. <br>• The system also comprises of a smoke detector which detects smoke particles and generates current that triggers an alarm. <br>Types of fire alarm systems <br>There are three types of fire alarm control panels which are conventional, addressable and intelligent. <br>Conventional system<br>• A conventional hard wired system has a simple control unit which monitors power supply and initiates notification signals. <br>• A conventional programmable system can be customized to meet user requirements. <br>• In a programmable system circuits can be programmed to control water flow of sprinklers according to the intensity of fire. <br>Addressable system<br>• An addressable system is a device which is assigned to a unique number.<br>• This system transmits electronic messages through a signaling line circuit which is connected to the control panel.<br>• Addressable devices transmit electronic message back to the control unit in the event of fire.<br>Analog system<br>• An analog system is similar to an addressable system but involves manual operation. <br>• This system collects data from smoke detectors and analyses the intensity of smoke and sounds an alarm. <br>Visit yellowpages-uae.com for Fire Detection Equipment and Systems in Dubai i.e. at http://www.yellowpages-uae.com/uae/dubai/fire-alarm-systems<br>
