Autowatch Alarm Gone Silent

[GoHard]

Hey all,

I have an autowatch 456 rli alarm, and it has stopped making sound. No chirps and when alarm is activated only lights flash, no siren.

I have contacted autowatch and am told that 95% likely the siren has died...

Basicly does anyone know how I could 'test' the siren out before I potentially waste any money on a siren?

cheers

Cut the wires going into it

Well tbh I was thinking about like... Yea snipping them with a crimper on standby with earplugs because I know that should set it off... But I also know if it does go off, im gonna need more than a crimper to shut it up. Maybe manual anyone?

Cutting the wires may not be the best way to test it. The 378001 Digital Back up battery siren will not trigger if the alarm is disarmed, not only that but if you cut through the siren cable you may short it out and cause more damage. Usually if a siren faulty you can trigger the alarm and with the siren in your hand and still wired in, shake it around and hit it with your hand. If it rattles then its RS. If it starts to work when hitting it while the alarm has been triggered and cuts off again, then there may just be broken connection inside the siren or the internal batteries have exploded and the siren is RS. If everything looks ok then check that it has 12v+ and 12V- at the siren end. You can replace the siren with a normal analogue back up battery siren (key switch on it), which you can probably purchase for around $40 but you would need to program the alarm for "negative siren output" instead of digital siren output which it is now.
