Mains powered siren

[wwwebber]

How reliable are your "whole bunch of motion sensors" in not giving false alarms. Can you ensure that the alarm (?) will not trigger when a person is close to the siren. ?

Why hide a 107 db siren when a much less powerful sounder would wake you without the significant risk of hearing damage,

And as has been said if the issue involves loss of mains power you will not be made aware as the siren will not be able to operate.

Can you suggest one that will work with my setup thats not so loud ?

Plug in psu 12v to siren .... remote plug turns on ....siren goes off !

Yep, thats what I'm looking for. Not sure but I dont think it comes with a 12v supply so I'll have to get one. cheers

The choice of alarm sirens that work from 230 Volt mains is limited as alarm systems ( normally have to remain operational during a power cut and hence operate from battery supplies of 12 to 48 volt. You have already been advised to use a mains to 12 volt power supply to feed a 12 volt sounder.

For example http://uk.rs-online.com/web/p/electronic-sounders/0626141/

Rather than having one ear damaging sounder to blast out through the entire house you could have several sounders around the house connected by 12 volt cabling to the power supply plugged into the remote switched mains soclet.
