OriginalBoffy Posted July 9, 2014 Posted July 9, 2014 After removing an old PIR from an Accenta G4, I carelessly left the 13v and 0v wires touching each other for a day or so. I only noticed when I later did a walk test, and all the zones with powered sensors (PIRs, Vipers) were showing as open. I've now separated them, but I still don't seem to be getting the 13v supply to the powered sensors. From the manual, it looks like there are fuses protecting the battery, speaker, siren/strobe and RKP supplies. There's no mention of the sensor suppky being fused, and the 4 fuses on the board look intact. I've ordered some replacement fuses, more out of hope than really believing that will fix it. Does anyone know what might be the problem or solution? Have I just fried that 13v supply? Thanks
Alarm Protection Posted July 9, 2014 Posted July 9, 2014 The fuse has blown. Use a meter to test then replace fuse. !
effortless Posted July 9, 2014 Posted July 9, 2014 I do hope you don't play with mains. Nothing like 230v up the kisser amirite?
OriginalBoffy Posted July 14, 2014 Author Posted July 14, 2014 Thank you, Alarm Protection, it was exactly that. In case it's useful to anyone in future, it seems the sensor power on this alarm is protected by fuse F2, "Speaker".
Adi Posted July 14, 2014 Posted July 14, 2014 I do hope you don't play with mains. Its ok, only blows the fuse. I really can't be ar**** with it anymore.
Alarm Protection Posted July 14, 2014 Posted July 14, 2014 Your all just jealous I got the best answer award on TSI! !
Cubit Posted July 14, 2014 Posted July 14, 2014 Its ok, only blows the fuse.If one in circuit.Comment from the op earlier suggested he didn't expect a supply to be protected.
Adi Posted July 14, 2014 Posted July 14, 2014 it was a tongue in cheek answer mate. I really can't be ar**** with it anymore.
