Ajax alarm

[dave7108]

Can anyone with one of these systems advise if the sensor below needs another sensor to make "the beam" up. I want to protect a bifold 3m door. So would I need just one of these sensors?

Thanks

I've got an Ajax system and have been looking into the external curtain sensors - I haven't got around to getting any fitted yet, but my understanding is that you only need the one sensor to cover your chosen area i.e. a run of bi-folds or a set of sliding doors etc.

Just one will do.

That's great just what I need to cover my patio doors.

As a side note where would be best to mount the base station? I currently have a switch in the loft for the CCTV etc so at the moment I've put it there. The bonus of having it somewhere downstairs I guess is the added bonus of an alarm although I do have the wireless sounder as well.
Can someone smash the box and disable it? It does have ethernet and 2g connection.

Ajax stuff looks good, but can you actually buy it directly?
