Suits my purpose
on 20 November 2012
I wanted a perimeter alert to warn me of anyone approaching my front door and side gate - and this does precisely that.
The sensors fix over just one screw (I would have preferred the unit to be permanently fixed and the cover then to be screwed on, but hey ho) and are permanently active. These take a PP3 battery (the rectangular one)
The alarm body can be slid over two screws or left freestanding to move around as desired. It can be set to 'high' or 'low' in 'alarm' and 'chime' or turned off completely. It takes 3 C batteries.
The fixings are provided, but I found the screws to be slightly too large - not a problem for me, we've got hundreds of the things.
The chime is great - I can take the main unit into the garden and can now get to the door before impatient delivery men leave. It works fine from the front of the house to the back and out into the garden - but perhaps distance could be limiting the signal for some reviewers? I've had mine less than a week, so can't vouch for battery life.
