The cabinet/box in which control panel equipment or devices are mounted. Back boxes may be installed on the wall surface, flush into the wall, or semi-flush to the wall.
A secondary energy source for the fire alarm system which ensures operability in the case of primary AC power failure.
An integral power supply element which maintains the batteries at a constant charge level in normal operating mode under primary AC power.
The period of time for which the batteries must fully support the operation of the system equal to the specified Alarm Time plus the specified Supervisory Time, as determined by the local jurisdiction.
In a projected beam detector, light is transmitted and monitored between a source and a photosensitive receiver. When smoke particles are introduced in the light path, some of the light is scattered and some absorbed, thereby reducing the intensity of the light reaching the receiver, causing the detector to activate.
An integrated computer system for monitoring and controlling various aspects of a building’s operation including heating, lighting, air conditioning, etc.
A duct detector draws air samples through piping or tubing from the air duct to the detector sampling ports. At the detector, the air sample is analyzed for products of combustion by ionization or photoelectric methods.
A secondary source of electrical power independent of the primary power supply, used to power the fire alarm system in the event of primary failure–usually batteries and/or an emergency generator.
A resistor installed at the end of a device wiring loop to establish a supervision current back to the control unit.
