Adding the Merlin M102
non-contact beam sensor
(Optional)
Non-contact Near-Infra-Red beam sensors are optional but may be required in EC countries. Mer-
lin strongly suggests they be fitted for increased levels of safety.
If sensors are fitted the opener will only close when the sensors are fully functional and where their
beam is unobstructed.
The sensors should be placed either side of the door opening, within 300mm of the door’s open-
ing, and within 100mm of the floor. Choose positions that will protect the sensors from accidental
impact or water. If one sensor is marked ‘receiver’ then do not place that sensor where it will be
subjected to bright direct sunlight. The high level of Infra Red light in bright sunlight may temporar-
ily prevent normal operation of the opener.
Switch off the power to the opener. Run the pair of cables from each sensor back to the accessory
terminals on the rear of the opener.
There is no need to connect the cables with any particular polarity.
Switch the power to the opener back on. Aim the sensors at each other using the adjustments
provided. When correctly aligned and unobstructed the sensor LEDs will stop flashing and stay on
continuously.
The door can open regardless of the sensor beam. Only the closing operation is affected by the
state of the beam. If the beam is obstructed or if the sensors are not functioning then the door may
still be closed by holding the manual control button down for at least two seconds, and keeping it
held until the door is closed.
