Pair of Doors
Two openers may be used to open two side-by-side doors. The doors may be synchronized or not. This operator is
not compatible with over-rebated doors.
Synchronized doors
The doors behave as if they are mechanically interconnected. In case of a presence at one door, both doors react
identically. In case of an obstacle at one door, the other door stops too, though a bit afterwards.
Wiring:
• Connect the grounds of the two controllers together
• Connect the motion sensor to both controllers, in parallel
• Connect each presence sensor from each door to both controllers, in parallel (but not the DATA line)
• Let each controller power its presence sensors (either controller can power the motionsensor)
• Connect a single Program Switch to both doors, in parallel
• Connect the RXD line of each controller to the TXD line of the other controller
• If you use the “Fire” input, connect the fire sensor to both controllers.
• If you use the “Break-out” input, connect the break-out switch to both controllers.
• Power the controllers from the same AC power source
