I have a brickbuilt & alarmed workshop at the end of the garden. Main access is via an electrically opened, remote controlled, up/over garage door. This opens onto a narrow lane and is not visible from the house. A lamp, visible from the house, comes on if this door is open. A couple of years back I suffered 9 attempted burglaries, 8 of which were through said up/over door. This door now has internal bolts at each corner and so cannot be opened from the outside without physically ripping the door and frame from the structure. The only other access is via the garden. This is causing a problem as I (and dog) am wrecking the grass and need access constantly. Been trying to figure a way of having electrically operated bolts in the 4 corners of the up/over door that could be opened by the presently installed remote control. My thinking is that as the bolts are shot they could each operate a microswitch that would then operate the door opener when the circuit was completed. Any ideas please if this is viable or any ideas for a more simple method? Also, where could I get solenoid type bolts to suit. Hope this makes some sense. Many thanks.
