Guest advent750 Posted November 2, 2004 Share Posted November 2, 2004 Hello all I am having a problem with an alarm system, as usual there are no manuals available. On the board there are a few names , Pulsar 6, Abacus 6R. It also has an extension board fitted and two keypads. The problem is on the keypad there is a message saying TRB Power and sometimes changes to TRB Supply. The alarm wont set properly because of this. I have checked the supply and changed the 12v TX. Any advice would be greatly appreciated. Also is there anywhere I can get the manuals for this alarm system. Thanks Link to comment Share on other sites More sharing options...
Service Engineer Posted November 3, 2004 Share Posted November 3, 2004 I have checked the supply and changed the 12v TX Why..?

Guest advent750 Posted November 4, 2004 Share Posted November 4, 2004 I changed the 12v tx because it was giving out 20 volts, which i think is a bit high. Do you think this could have damaged anything on the board. Link to comment Share on other sites More sharing options...
Service Engineer Posted November 4, 2004 Share Posted November 4, 2004 No it wasnt, infact thats probably about right. Most panel TX `s will show between 18 &24VAC while no load is present. ........................................................

bellman Posted November 4, 2004 Share Posted November 4, 2004 I changed the 12v tx because it was giving out 20 volts, which i think is a bit high. Do you think this could have damaged anything on the board. 30328[/snapback] No No No, the tx output has to be higher than the load requirements to give enough headroom for the regulation circutry to function correctly. Put the original one in as soon as possible. Regards Bellman Service Engineer and all round nice bloke ) The views above are mine and NOT those of my employer.

Service Engineer Posted November 4, 2004 Share Posted November 4, 2004 Yeah, so looks that way. I`d replace the origional TX if you still have it. ........................................................

Guest advent750 Posted November 4, 2004 Share Posted November 4, 2004 if i replace the battery that should solve the problem. The problem stopped the alarm from being set. Link to comment Share on other sites More sharing options...
Service Engineer Posted November 4, 2004 Share Posted November 4, 2004 Maybe on the 1st attempt at setting, a second immediate attempt should have allowed setting as normal with perhaps an error message while setting. ........................................................
