The BEAMMMK allows reflected beam detectors and reflectors to be mounted to
either a vertical wall or the ceiling. The kit allows for additional alignment
range in cases where the detector and reflector cannot be mounted within 10
degree of each other. The kit includes the hardware necessary to mount either a
single transmitter/ receiver unit or a single reflector. (To mount the
transmitter/ receiver the surface mount kit, BEAMSMK, must also be used). If the
transmitter/ receiver and the reflector require additional alignment range two
kits are required.
