Features
¨
Fail-safe operation
A fail-safe operation is available on all sectored
outputs, if loop communications are lost for a defined
duration then the sector outputs will be turned ON.
Sector outputs will turn OFF immediately when
communication is restored.
¨
Synchronisation
Adjustable synchronisation pulses can be selected
for all sector outputs to synchronise the operation of
devices such as xenon strobes or speech sounders.
¨
Auxiliary Output
The Auxiliary output can be programmed to
automatically turn OFF when a mains failure occurs
to preserve battery capacity. The output can also be
programmed to provide a reset pulse when a fire
reset occurs.
