Remote Station and Protected Premises Fire Alarm Systems

Protected Premises

Circuits

Protected premises fire alarm systems can operate using different types of circuits.  Circuits connect the components to the fire alarm control unit, as well as provide paths for interfaced equipment and combination systems.

Initiating device circuitsInitiating device circuits connect simple closure-type devices such as manual pull boxes or detectors to the fire alarm control unit. The initiating device circuit is also known as a zone-module or conventional circuit. The location of the activated device is not known specifically, but the "zone" that contains the activated device is annunciated at the control unit. connect non-addressable input devices to the control unit.  Signaling line circuitsThese are intelligent circuits which can handle multiple bits of information simultaneously. The control unit is a microprocessor, and interrogates the components on the circuits so if a fault or a signal occurs, the control has the ability to specifically annunciate the signal. connect addressable components to the control unit, and notification appliance circuitsVery simply, notification appliance circuits connect all notification output components to the fire alarm control unit. When an input device signals the control unit, the control unit turns on the notification appliances. connect output devices to the control unit.

All of these circuit are discussed in depth in a separate course covering basic fire alarm system circuits.
