Openers & Access
Wall-mounted openers sit beside the torsion shaft instead of on the ceiling, which leaves room for storage, a car lift or a high-lift door. Installing one is a change in layout as much as a change in motor.

The two small eyes near the floor
The photo-eye sensors are inspected together with their wiring. Each sensor carries a small indicator; a steady light on both means the beam is aligned, while a flicker, a dark light or one that goes out when the bracket is nudged points to misalignment, a loose mount or a damaged wire. The technician sights along the beam, looks for obstructions, cobwebs, frost and low sun on the receiving lens, checks that the sensors sit no higher than about fifteen centimetres off the floor, and traces the wire back to the head unit for staples, kinks and chew marks.
Sensor faults are the single commonest reason a door refuses to close.
