unit with the multi-mount kit (BEAMMMK).
The kit includes the following parts:
Qty. Description
1 Plastic surface mount box
4 #8-32 × ½" screws
MOUNTING INSTRUCTIONS
1. Read the installation instructions of the beam detector to determine the
appropriate number of wires to be used.
2. Drill the appropriate holes to mount the surface box to the wall using
the drill centers on the backside of the surface mount box (see Figure
1). Hole locations other than those provided by the drill centers are also
acceptable.
Note:If the surface mount box is to be mounted over a recessed junction box
the backside of the box may be removed by scoring the insert with a sharp
knife and then carefully breaking the insert out (see Figure 1).
3. Drill the appropriate holes for the conduit using the drill centers provided
on all four sides of the surface mount box (see Figure 1). Conduit sizes of
½" or ¾" are acceptable.
4. Mount the surface mount box to the appropriate location on the wall us-
ing the mounting holes drilled out in the previous step.
NOTE: For proper operation of the beam detector, the surface mount box must
be securely mounted to ensure no subsequent movement of the beam detec-
tor will occur after the installation is completed. See “Detector Placement and
Mounting” sections of the beam detector manual for further details.
NOTE: For proper operation of the beam detector, the surface mount box must
be mounted to ensure there is line of sight between the transmitter/receiver
unit and the reflector. See “Detector Placement and Mounting” sections of the
beam detector manual for further details.
5. Pull wiring and conduit through the drilled hole(s). Attach nut(s) (not in-
cluded) to conduit fitting and tighten. Be sure to leave enough wire to reach
the transmitter/receiver unit when attached to the base.
6. Attach the transmitter/receiver unit securely to the base using the four sup-
plied #8-32 × ½" screws.
7. Complete the installation of the transmitter/receiver unit using the instruc-
tions included with the beam detector.
8. Test the system as indicated in the beam detector instructions.
