Hi,

I'm planning to replace the alarm system at a house I just moved to and would appreciate some advice on the type & location of sensors to use in the garage.

It is a detached double garage roughly 6m square, one piece up & over door, medium sized window at the back (south facing) plus an entry door & window in one side wall (door against back wall).

The door is fiberglass.

The back window will get full sun, & through tree branches later in the day.

Is there any type of area sensor that I can use in the garage that wouldn't be subject to false triggering?

Any ideas appreciated,

Robert Jenkins.

Simple answer to that question is a no, if you could design one you would be a very rich person.

There are thankfully some which are more unlikley to trigger than others and the type you need would known as a dual technology sensor (dualtec for short).

Many manufactures make them and many different engineers will have theyre own favorite. I am sure within 24hrs you will have a fine list to choose from as the guyz come in from work and post theyre choice.

I personally don

Optex MX40

C&K dualtechs seem fine if you set the microwave part of it just high enough to trigger from internal movement and no more.

Texecom premier DT is also a good piece of kit.
