Hi all,

I have a wired house alarm that i fitted some years back.

A while back I added a wireless panic button for SWMBO. This has a single hand held button pad and a powered receiver next to the wired alarm box, which presents clean contacts to one of the zones of the wired alarm. This is is defined as a panic alarm zone.

So, I want to start putting sensors in areas that have no cable access, like the garage. I can't find any ready made door or window contacts that are wirless and wirelessly connect back to a receiver like my panic button does.. All I can find are wireless sensors for wireless alarm systems.

If I could find a small generic battery powered transmitter that alerts a base station with clean contacts, I can make my own wireless sensors anywhere.

Any suggestion for such hardware ? - Got to be cheap and cheerful, nothing fancy, just a button that remotely opens a clean contact on a central box, connected to an alarm zone. Aesthetics dont matter, as the use case is for places like the garage.

Thanks

Chris

If you Google the Ultimate Handyman forum, one of the sub-forums on there is about alarms and there are lots of experts who could probably answer your question. There's also DIYNot

Have you considered a wireless switch (such as your panic button) and
modifying the switch bit to activate with the door contact and not the
actual button press on the switch?

I once did something similar with a door contact a wireless doorbell to
activate the doorbell in the house.

Wireless doorbell - that's a good idea. Can't be difficult to adapt the electronis to close a contact.

Will look into that.
