Good evening!
Don’t have a huge deal of experience with fire alarms but having to work on a conventional system at the minute with various signals and “shut offs” being activated by the on board relays.
All relay outputs currently used up in the panel but need to setup another “shut off” for an extract fan.
Planned on installing a 230V DP NC contactor with a 24V coil which could be fed from a sounder circuit but then didn’t know if this would work as it may need to be polarised - can anyone advise on this?
There’s a 24V polarised relay within the system fed from the panels relays. Is it feasible to double up in its supply terminals and take 24V from there?
Any advice appreciated.
Thanks.
