GUnit Posted May 19, 2009 Share Posted May 19, 2009 hi folks i moved into my home about a year ago with the above alarm fitted with a DSC power832 ... pc5051 problem is the alarm system is not working no output on control box or keypads. its like there is no power going to it but.... i have checked the "spur socket" next to it and replaced the 13A fuse i have checked the power connection in control box to make sure there is 240V coming in i have replace the 1A fuse inside box i have replace the battery with a new one i am all out of ideas at least if it was working it might give me some iea of any faults lol any ideas would be great many thanks G unit Link to comment Share on other sites More sharing options...

Not familiar with this panel but on most panels there will be a pair of wires coming from the transformer and they will be connected to the PCB either by plug or via screw connectors. I would expect to see between 17 and 25 volts AC at these wires. Obviously this is a test which has to be done with the mains supply on so great care is needed and if you're not confident call an experinced engineer.

GUnit Posted May 19, 2009 Author Share Posted May 19, 2009 think i will take a pic of the inside of control box then you can point out which parts you want me to get a voltage reading from as there is AC power block connections with a fuse the come from mains supply to block connector then out the other side with 2 x red wires to a metal box shape that is held in place with 2 nuts , this metal small box has 2 yellow wires running to the mother board hope this helps lol can you tell which parts to take a reading from Link to comment Share on other sites More sharing options...
marx Posted May 20, 2009 Share Posted May 20, 2009 U can try it off the battery to see if the panel is ok. connect battery and then use a spare wire and take minus from battery and connect to zone common (just for 2sec) on board, then disconnect wire and your panel should work off the battery. If it wount work then u might have short in detector cable, then disconnect 12V for detectors but u have to watch that u keep keypad cable connected!

Again, be very careful with mains voltage. Link to comment Share on other sites More sharing options...
GUnit Posted May 20, 2009 Author Share Posted May 20, 2009 whats the best way to check the transformer is putting out 17-25v? also does both keypads need to bee working? as the one inside the house is ok i think but the one below control box has been ripped off and i dont know where it is as it was done before i moved in.

marx Posted May 20, 2009 Share Posted May 20, 2009 no u dont need 2 keypads one will be ok. just check that the one is missing that the cable is not shorted or something, minght be that thats where your problem is!! u need a mulitmeter to mesure the voltage.

GUnit Posted May 20, 2009 Author Share Posted May 20, 2009 ok yeah i have a multi metre to measure it wit i meant where about will i take a measurment from? lol Link to comment Share on other sites More sharing options...
aismoresecur Posted May 20, 2009 Share Posted May 20, 2009 With your meter on AC volts, measure across the two yellow leads Link to comment Share on other sites More sharing options...
