I've fitted my own alarm system and i'm very happy with it. The panel is a Bosh Abacus Evolution. The sounder is a Texecom Odyssey.

This is completely non-standard, but so I can tinker without disturbing my neighbors, I've installed a secret switch inside the house and taken a seperate wire from the sounder to this switch. This wire breaks into the connection to one side of the siren. I was surprised to find that when the switch is in the off position, the siren still sounds at about 25% of the normal volume. So I assume that this must be caused by inductance along the wire. To make sure, I disconnected the switch altogether and got the same behavior. ie at the switch end, the ends of the wires were not connected to anything.

Can anyone suggest anything that I can connect into the circuit in order to stop this happening?

Thanks in advance?

I can't help with that particular problem , but the Texecom sounders have an engineer function , that can be invoked when doing maintenance / tinkering.

That sounds useful. How do I invoke this?

Its in the manual that comes with the sounder , and also in most of the Texecom Alarm Installation manuals.

so the wire to the siren in the bell box is in series with the switch? the switch goes open and the siren still works at 25%?

possibly there two sirens in the bell box and you have only connected one through your switch?

You need to use a double pole switch then to break both connections to the sounder, although I don't recommend fitting anything that will intentionally prevent a sounder from working like that.

id be vary cautious here as it sounds like you have broke into the piezo wire. if so there is a lot of voltage going to those 10-20000v if i recall

same as a strobe. also if someone removes your sounder from the wall it wont sound

Back to the manual then and use the engineers hold off facility.

I've been digging around. I cant find the documentation that came with the sounder. I had a look on the web and although I found some documentation, it didn't explain about the engineer mode in a way that I could understand.

Sorry we cannot tell you how to do this in the public area, see the site rules.
