Appendix 7 – Glossary of Terms
Addressable System: A fire alarm and detection system that contains addressable control devices.
AL1: Access Level 1 (for general users).
AL2: Access Level 2 (for authorised users).
AL3: Access Level 3 (for authorised systems engineers).
BS 5839-1: Fire detection and alarm systems for buildings: Code of practice for system design, installation and
maintenance.
BS 7671: IET Wiring Regulations.
BS EN 54-2: Fire Detection and Fire Alarm Systems. Control and Indicating Equipment.
BS EN 54-4: Fire Detection and Fire Alarm Systems. Power Supply Equipment.
DST: Daylight Saving Time.
EOL: end-of-line resistor.
Input Device: Any device that can signal an event such as 'fire', 'fault', etc. to the fire alarm and detection
system, e.g. fire detectors, manual call points, I/O units.
Input Group: Comprise of grouped input devices and used in the C&E programming (max. 500).
Input Groups include detectors (smoke, heat, multi), MCPs, inputs of I/O units, panel keyswitches, inputs of A-
Bus PCBs, monitored inputs.
Input Supergroups: Comprise of selected Input Groups and used in the C&E programming (max. 32).
I/O: Input/Output (device) - device that is connected to a fire alarm and detection system and is used to receive
and/or transmit information within the system.
N/C: Normally closed (relay contact).
N/O: Normally open (relay contact).
Output Device: Any device that can act on a command from the fire alarm and detection system, e.g. sounder,
VAD, relay, I/O units.
Output Group: Comprise of grouped output devices and used in C&E programming (max. 500).
Output Groups include loop sounders and conventional sounders, VADs, outputs of I/O units, outputs of A-Bus
PCBs, panel relays.
Output Supergroups: Comprise of selected Output Groups and used in C&E programming (max. 32).
SD: Secure Digital (memory card). A non-volatile micro memory card fitted internally at CONN1 on the
Control/Display Module PCB.
Supervisory: Non-fire related action, e.g. open a door, start a fan, etc.
System Devices: Include panel sounder, panel relay, panel keyswitch, panel touchscreen, etc.
Zones: Geographical location of a device (max. 200 zones per panel).
