Fire Alarm System Into Intruder Alarm


Recommended Posts

yes it would work as lsong as your main current is taken from the psu.

So I would use the main board and psu in the panel to run the PCB & Detectors & RKPS etc and prob one sounder strobe and the Smart PSU to run the other sounders and house a 2nd battery.

Two 12v 7.2aH should do the trick shouldnt it ?

what is the total MA draw you have?

Guessing will not meet regs.

Regs are for pro's ... which I aint :-)

Are we talking passive draw or full active draw ?

Passive draw with all PIRS open is about 291mA without the keypads, PCB etc

Active draw is approx 1.4A

So 2 x 12v 7.2Ah batteries would provide 8.4Ah's nearly 29hrs of standby - is that right ?

both to be fair

i have released our calc program on here which can do battery sizing for EN regs. granted you dont need to comply to all the regs, but some you should. batteries are one IMO
