MOUNTINg AND WIRINg INSTRUCTIONS:
TRANSMITTER/RECEIvER
The BEAMSMK accessory must be used with the transmitter/receiver to pro-
vide wiring entry. Refer to Figures 2 through 4 for this step.
1. Read the installation instructions of the beam detector to determine the
appropriate size and number of wires to be used.
2. Drill the appropriate holes for the flexible conduit using the drill centers
provided on either the sides or the back of the surface mount base. See
Figure 2 for details. Note that the top of the surface mount base contains
mounting bosses for the “L” brackets used in the next step. Conduit sizes
of
1 /
2
″ or 3 /
4
″ are acceptable.
3. Assemble the “L” brackets to the surface mount base using the two #10-
24 × 5 /
8
″ screws and two #10 split-lock washers provided. See Figure 3 for
details. The screws should be fully tightened.
4. Assemble the “U” bracket to the “L” brackets using the two #10-24 ×
1 /
2
″ screws and fender washers provided. See Figure 3 for details. The
“U” bracket should be assembled to the “L” brackets so that the words
“DO NOT PAINT” appear in the front of the assembly. Tighten the screws
until almost snug. The assembly should tilt freely in either direction. The
screws will be fully tightened later when the alignment is performed.
5. Insert the flange of the “U” bracket into the keyed hole of the wall or ceil-
ing mount bracket. Slide the bracket forward into position. The surface
mount base should now hang from the bracket.
6. Insert the correct screw and washer combination (either wall or ceil-
ing mount) through the slot and into the hole of the mounting bracket
flange. Tighten the screw until almost snug. The assembly should still
turn freely in both directions. The screw will be fully tightened later
when the alignment is performed.
7. Pull the wiring and the flexible conduit through the drilled hole(s). At-
tach nut(s) (not included) to conduit fitting and tighten.
Notice: This manual should be left with the owner/user of this equipment.
gENERAL DESCRIPTION
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° of each other. The kit includes the hardware necessary to mount either
a single transmitter/receiver unit or a single reflector. (To mount the trans-
mitter/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. The kit is not compatible with the long-range reflector kit
(BEAMLRK).
The kit includes the following parts:

MOUNTINg BRACKETS
Install a ceiling or wall bracket so that when mounted, the transmitter/re-
ceiver and the reflector will have a clear line of sight between them.
The ceiling bracket is composed of two parts that should be assembled with
the inside part between the ceiling and the outside part as shown in Figure 1.
The brackets should be mounted so that the slot in the front of each bracket
is facing the other bracket. Mount the brackets only on solid structures of the
building. To avoid unwanted alarms due to wall movement, do not mount to
flexible walls, such as sheet metal walls (see Mounting Locations section of
the transmitter/receiver manual for more details).
