You want to know when something is happening, especially if it is not a good thing. FM Approved signaling equipment is designed to let the end user know when something is going awry. Electrical protective signaling systems are components used to produce alarm and supervisory signals indicative of fire, smoke, sprinkler water flow or other emergencies in the facility. System configurations are classified according to where and how the signals are received. The categories are commonly designated as:
- Central station
- Emergency communication
- Emergency voice/alarm communication
- Remote station
The suitability of any system application should be judged on the basis of the hazard(s) being protected and the manufacturer’s instructions.
