Please help scantronic 9427 no power to keypad and siren going off

[Charn]

Hi all, at 3am this morning my internal alarm went off and they key pad showed no power. Then I disconnected the internal sounder. At 3:30am the external siren went off and I disconnected the internal battery in the metal box and pushed the fuse down in the fuse box. At 4am the external siren has gone off. My first priority is to stop the external siren going off again...will it...? Any advice I am grateful for

Thanks
Charn

Probably faulty battery if it's not been replaced in the last 5 years ! Was the battery hot ?

Should be ok , don't bothers to this stage ....I would disconnect the positive for the bell in the panel ( this will stop the external bell from activating ) then power system back up battery first ...does the keypad come back to life ? If your code does not work try 1234 ...
If all ok power down and repeat above with switching mains 240 back on ( not battery )
If ok reconnect battery , bell positive and box up and reset , now test alarm

Hi keypad didn’t work once I followed your first step, so I have changed the battery and the keypad is back on but the tamper light is on, how do I get the power light on please? I don’t have a engineer code, any suggestions please?

What lights come up ? Are they powered detectors e.g. Pirs ? Do the pirs light up when you walk in front of them ? If not the aux fuse may have blown

No lights on the control panel, but it is on as the button are all backlit. The PIRs work. I just need to reset it I think. When I put in the code their is a continuous tone then the alarm goes off....

And what shows on the keypad when it goes off ?

Have you put the mains back on?
You may not have certain LED's illuminated on the RKP if the system is running on battery alone.
