Address

Addressable devices are given an individual address so their exact location can be identified. See Analog Addressable and XPERT Card for more information.

Addressable System

A system in which signals from detectors, or any other devices are individually identified at the control and indicating equipment.

Air Sampling Unit

A device used to detect smoke within ventilation systems.

Alarm

The state which a device enters when a fire is detected, signaling an emergency.

Analog

An analog signal is one which goes up and down smoothly. Analog fire detectors are not restricted to two states - alarm/no alarm - as conventional detectors are.

Analog Addressable

The term used to describe a fire detection system incorporating analog detectors which are also identified by a number or 'address'.

Analog addressable detectors provide location-specific information on the ambient level of smoke, heat, or other product of combustion (ie, carbon monoxide).
