Need a bit of advice....
A friend wants their garage alarming. The main garage door is separated into thirds, with 1 third of it being the main door, and 2 thirds another door that cannot be opened without opening the main door. There are no windows, and the garage is only 4 foot deep.
My initial advice was to get some better physical security, as there is only 1 way in and out, however he is insistent on having it alarmed, and doesn't want it on the house alarm. Now the hard part...
The door is magnetic, as is the frame, and because the door is split into thirds, a standard roller shutter contact cannot be used. The door opens outwards. A Dual Tech could be used, but the entry time needs to start when the door is opened, and the pir needs a fair bit of movement for it to trigger.
At the moment, my thoughts are:
1)To put a viper on the door, detecting forced entry, and have a dual tech to start the entry time. (Although this doesn't feel right)
2) Have an external keyswitch for arming and disarming. The PIR activating immediately should anyone break in
Is there anything that can cancel out the magnetic field, and is it reliable?
What would the Pro's do here?
Much Appreciated
