Addressable System
Analog System
A conventional hard wired system has a simple control unit which monitors power supply and initiates notification signals.
In a programmable system circuits can be programmed to control water flow of sprinklers according to the intensity of fire.
Conventional system A conventional programmable system can be customized to meet user requirements.
An addressable system is a device which is assigned to a unique number.
Addressable system This system transmits electronic messages through a signaling line circuit which is connected to the control panel.
Addressable devices transmit electronic message back to the control unit in the event of fire.
An analog system is similar to an addressable system but involves manual operation.
Analog System This system collects data from smoke detectors and analyses the intensity of smoke and sounds an alarm.
