General Information
The Model 234 Stanchion Assembly is part of a completely integrated emergency communications
station. The Model 234SBA Stanchion Broadcast Assembly helps to insure public safety by combining
two-way communications with one-way public address broadcasting.
The Model 234 Stanchion Assembly and Model 234SBA Stanchion Broadcast Assembly are designed to
house a GAI-Tronics 39x or 27x Series Flush-Mount Telephone and a Model 530-001 or 531A Strobe.
Both stanchion assemblies are over 9 feet tall, making it easily located by potential users. Each Model
234SBA is capable of being equipped with up to four public address speakers.
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 complete emergency stanchion, with or without public address, is shipped in two stages. The Model
84504-201 Hardware Kit is usually shipped in advance followed by the remaining assemblies (Model
84501-201 or Model 84509-201 Stanchion Body, Model 84502-201 Clear Lens, and Model 84503-30x
LED Panel Light Assembly). Both the Model 234 and Model 234SBA use the same hardware kit.

Mounting
A concrete pier is required to support both of the
stanchion assemblies. GAI-Tronics provides the
Model 84504-201 Hardware Kit to aid with the
construction of this pier.
We recommend using 3,000 psi grade concrete
as a minimum. The pier must be strong enough
to support a structure that is 9-1/2 feet tall and
weighs 250 lbs.
Reinforcement Cage
We recommend that the concrete base be 3 feet
deep and 18 inches wide, and that a
reinforcement cage be used. The reinforcement
cage is not provided by GAI-Tronics. The
following materials are necessary to construct the
reinforcement cage:
Figure 1. Model 234SBA shown
four #4 rebars;
three #4 ties;
one 18-inch sonotube.
1. Construct the reinforcement cage by placing a horizontal
member in the center of the rebar.
2. Place the two remaining horizontal members 12 inches
from that center point. See Figure 2. The top of the
cage should be 3 inches below the top of the pier.
3. The reinforcement cage in Figure 2 shows the maximum
diameter that is suitable for a customer-provided 18-inch
sonotube.
4. Install two conduits in the pier—one for the telephone
wire and one for the electrical power wire.
