General Information
The Model 234WM-202 Wall-Mount Stanchion Assembly is part of a completely integrated emergency
communications station and is designed to house a GAI-Tronics Model 39xor 27xSeries Flush-Mount
Telephone and a Model 540-001or 531A Strobe (each sold separately). The stanchion is a simple,
attractive, yet highly visible unit measuring 40.5 inches (1.03 meters) tall.
GAI-Tronics enhanced emergency telephones are designed for isolated high-risk areas requiring
emergency communications equipment. Emergency telephone users simply press the clearly labeled
emergency push button for immediate connection to a user-programmed central security telephone
number.
The strobe creates added visibility to emergency telephone locations by providing a constant-on lamp that
automatically flashes when the emergency button is pressed. The telephone is also highly visible; a light
mounted in the stanchion shines on the front of the telephone to illuminate the telephone for nighttime
use.
The Model 234WM-202 Wall-Mount Stanchion Assembly consists of the Model 84505-202 Wall-Mount
Stanchion and the Model 84503-30xPanel Light Assembly (each packaged separately). The strobe and
the emergency telephone are purchased and packaged separately.

1. Align the stanchion panel light assembly inside the stanchion as shown in Figure 5.
2. Model 84503-301: Extend the black (hot), the white (neutral) and the green (ground) wires to the
base of the stanchion (these wires will be connected later, along with the strobe wires, to the incoming
power wires in accordance with the electrical codes).
Model 84503-302: Extend the black (−) and the white (+) wires to the base of the stanchion (these
wires will be connected later, along with the strobe wires, to the incoming power wires in accordance
with the electrical codes).

allow them to hang free.
8. The telephone front panel is shipped from the factory with a cable and modular plug attached to TB1.
If desired, an optional modular telephone jack can be mounted to the inside of the back box allowing
the use of the cable and modular plug that is attached to TB1. If the telephone line is to be hard-wired
to the telephone, this cable can be removed and discarded.
9. Attach the telephone cable from the surge protector to TB1 on the telephone PCBA as shown in
Figure 8.
10. Attach the strobe’s violet and orange control wires to TB2 on the telephone PCBA as shown in
Figure 8.
11. Install the telephone’s front panel using the six tamper-resistant screws and six washers provided.
NOTE:Excessive tightening will cause the panel to warp. Do not over-tighten.
Wiring Power Connection
All wiring connections should be complete at this point, with the exception of the stanchion panel light
and strobe wire connections to the incoming power lines. All connections must be made in accordance
with the National Electrical Code (NEC) in the United States or the Canadian Electrical Code (CEC) in
Canada. Install the power lines per Figure 8 for ac installations or Figure 9 for dc installations.

Repairing Surface Damage to Powder-Coated Stanchions
1. Carefully sand the damaged area to clean and score the base metal, taking care to minimize any
additional damage to the surrounding powder coating.
2. Wipe the sanded area with a cleaning solvent, such as DuPont “PrepSol” or equivalent. Allow the
area to dry. This type of product is normally available at auto parts stores. Denatured alcohol may
also be used.
3. Prepare the bare metal surface for painting by treating it with a phosphoric acid solution intended for
this purpose. The phosphoric acid solution is also normally available at auto parts stores. Allow the
area to dry.
4. Using a cotton-tipped swab or small brush, paint the prepared surface with an automotive enamel or
oil base polyurethane enamel such as Red Devil, Rustoleum, or equivalent. Do NOT use Krylon-type
paints. Carefully blend the repair enamel into the powder coat at the edges.
NOTE:Exact color matches may not be attainable.
