TheEnforcer Posted May 28, 2009 Author Share Posted May 28, 2009 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.

james.wilson Posted May 28, 2009 Share Posted May 28, 2009 ID personally put more load on the smart psu (as its rated at 3A) and less on the panel.

I didnt know that the smart psu was bigger, makes perfect sense. How do you size up the batteries then ?

Guest old-hand Posted May 28, 2009 Share Posted May 28, 2009 Two 12v 7.2aH should do the trick shouldnt it ? what is the total MA draw you have? Guessing will not meet regs.

TheEnforcer Posted May 28, 2009 Author Share Posted May 28, 2009 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 ?

james.wilson Posted May 28, 2009 Share Posted May 28, 2009 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 http://www.thesecurityinstaller.co.uk/comm...p;hl=techmaster securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
