Which Visonic detector for patio doors?

[JamesSchu]

I want to protect the patio doors at the back of my integral garage, but am not sure what Visonic Powermaster detector to use.

You can get from the garage into the house through an internal door, and the patio doors have vertical blinds, which I want to keep.

A standard door contact is not a straight fit due to the sliding nature of the doors (although could be adapted) and so I wondered if a shock detector or curtain PIR or something else would be better.

Any advice welcome. Thanks.

The Visonic SD-304 PG2 is combined shock sensor with magnetic door contact.Best device to protect this type of door from being opened or forced.
Curtain pir with blinds NOT a good idea.

That's sounds perfect! Many thanks Handymanjo
