Connect probes across auxiliary DC supply.Reading should be between 13.5 - 14VDC (Below 13V the battery will not charge, above 14.5V the battery will overcharge).To eliminate induced AC, fit an ACT 1313 12V spike suppressor.Induced AC reading should not exceed 1.2V.Connect probes across any DC+ and Earth.Disconnect 12VDC supply to PIRs, bells, battery etc in turn to identify fault.Excessive current in this or previous test indicates a system fault.Connect test probes in series with removed lead and power supply terminal.Disconnect either AC output lead to panel.Switch meter to highest AC current range.Reading should not exceed 1.2VAC (example shows 0.019V).Connect test probes across neutral and Earth.A difference of more than 1.2VAC means an Earth fault may exist.Reading obtained should be almost identical to previous reading.Connect test probes across live and Earth.Reading should be between 220 and 250VAC and reasonably.Connect test probes across live and neutral.Well, there are a few tests you can do with a simple multimeter that will narrow down the issue and hopefully give you something to tell the electrician or service company when they get there and potentially cut down service time or diagnostic charges. You just want the alarm fault fixed so you can go back to the more important tasks of the day without worrying about security, we get it. You’re probably at least a little bit panicked. The CR 1/2 AA, CR 2/3 AA, CR AA and CR 2/3 A mass series with highest capacity for all kinds of backup applications and the CR 2 NP, CR 2/3 AH, CR 123 A and CR 2 coiled high energy series for high discharge currents in communication and wireless sensor applications.Previous / Next Are you experiencing an Alarm Panel Fault?
