Wiring standards
All wiring must be installed in compliance with local codes, and in accordance
with the requirements of the local authority having jurisdiction.
Fire alarm systems must remain operative during the initial phase of a fire. It is
therefore important that certain wiring practices are followed, and must comply to
British Standard BS 5839-1: Sections 17 and 24.
WARNING:
The wiring connection to the extinguishant cylinder actuator is a low
impedance circuit, which can draw up to 1 A during actuation. Make sure that
wiring to the actuator is of sufficient capacity to avoid wiring resistance voltage
loss.
