Stanchion B roadcast Module Install ation
NOTE: For ease of installation, it is suggested that the Stanchion Broadcast Module be mounted to the
top of the existing 234 Series Stanchion before installing the speaker kits. This will reduce the weight of
the module and allow more areas to handle it.
1. Before installing the stanchion broadcast module, the existing strobe lens cover and strobe must be
first removed from the 234 Series Stanchion. To disassemble the lens cover, remove the four #10-32
screws from each side of the stanchion and lift off the lens cover.
2. Before disassembling the strobe, be sure to disconnect all the power and control wires from their
termination points. Remove the strobe by unscrewing it from the threaded nipple at the top of the
stanchion. Remove all wires from the nipple and place the assembly aside.
3. Before placing the stanchion broadcast module on the top of the 234 Series Stanchion, the existing
four #10-32 tapped holes must be drilled out to 0.313 inches. These holes will later be used to secure
the stanchion broadcas t module.
4. Place the stanchion broadcast module on top of the 234 Series Stanchion, sliding the module flanges
into the recessed top.
5. With the stanchion broadcast module now resting on the top of the 234 Series Stanchion, mark the
center of each of the four drilled 0.313 holes on the module flanges. Drill a 0.232 hole in each of
these four hole locations.
6. Use the supplied #1/4-20 stainless steel, self-threading screws to secure each flange. Be sure to
adequately drive and tighten these screws against the 234 Series Stanchion. Use all four screws to
properly secure the stanchion module. The four ¼-20 stainless steel, self-threading screws are
supplied with Model 12510-002 Small Access Panel Kit or Model 12510-003 Large Access Panel
Kit.
7. Follow the instructions for strobe installation contained on page 4 to secure the strobe before
installing the speaker assemblies. Follow the instructions in Pub. 42003-220 to install the antenna kit
before installing the speaker assemblies.

Strobe Installation
Before installing the antenna kit, mount the strobe according to the instructions below.
1. Insert the new strobe’s seven 15-foot wires through the stanchion module’s threaded nipple (center
hole), and through the threaded nipple on the existing stanchion. Allow the wires to extend to the
base of th e s tanchion. Se e Figure 2.
OTE: Wire lengths may need to be exten d ed prior to feeding t h em thr ough the thread ed nipp les.
N
Figure 2.
2. Screw the strobe onto the threaded nipple.
3. Separate the orange and violet wires necessary for the telephone connection, and extend those wires
through the stanchion cutout for the telephone; or extend the wires down to the opening for the access
panel in the rear of the stanchion body for connection to the paging module.

2. Make the wiring connection to the electronics module labeled 12V
battery cable. It is recommended that this be left disconnected from the module until you are ready to
power up the unit.
3. Attach the fast-on connectors to the batteries observing polarity (red+, black-) per drawing 73520.
4. Secure the batteries into L-bracket inside stanchion under phone opening.
