General Information
The Model 234 RED ALERT Tower Assembly is part of a completely integrated emergency
communications station. The Model 234SBA RED ALERT Broadcast Tower Assembly helps ensure
public safety by combining two-way communication with one-way public-address broadcasting.
The Model 234 RED ALERT Tower and Model 234SBA RED ALERT Broadcast Tower are designed to
house a GAI-Tronics 39xor 27xseries flush-mount telephone and a Model 540-001 or 541-001 strobe.
Both tower assemblies are over 9 feet tall, making them easily located by potential users. The Model
234SBA Tower can be equipped with up to four public address speakers.
GAI-Tronics enhanced emergency telephones are designed for isolated high-risk areas requiring
emergency communication equipment. Emergency telephone users simply press the 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. A panel light mounted in the tower shines
on the front of the telephone to illuminate the telephone for nighttime use.
The complete emergency communication tower assembly, with or without public address, is shipped in
two stages. The No. 84504-301 Hardware Kit is usually shipped in advance, followed by the remaining
assemblies (No. 84501-201 or No. 84509-201 Tower Body, No. 84502-201 Clear Lens, and No. 84503-
30xLED Panel Light Assembly). Both the Model 234 and Model 234SBA use the same hardware kit.
Tower Components
Each tower model includes components that are shipped separately for field assembly. The included
components are:

A concrete pier is required to support the tower assembly. The pier must be strong enough to support the
9-1/2 feet tall structure that weighs 250 pounds. The specific GAI-Tronics installation requirements
outlined in this manual provide a 140-mph wind speed rating (VULT). *Reference AASHTO LTS6 Risk
Category II International Building Code.
The GAI-Tronics No. 84504-301 Hardware Kit contains four anchor mounting bolts, a mounting
template, and mounting nuts and washers needed for installation. Additional materials required to install
the pier are not provided by GAI-Tronics but are shown in the installation drawings for reference.
Determine all conduit entries before pouring the pier.
Figure 1. Model 234 & Model 234SBA shown
Tower assembly installation requires the construction of a concrete pier with a rebar reinforcement cage
using 3,000 psi minimum grade concrete. Installation of the anchor bolts within the concrete is simplified
by using the provided template. Once the concrete has properly cured, the tower body is installed with
the nuts and washers included in the hardware kit. Leveling and spacing of the tower body is required for
proper installation. Detailed information on each of these items is provided in this manual.

Pier Foundation Depth and Conduit Entry
The pier should protrude a minimum of one inch above the finished grade when the surrounding area is
not concrete or asphalt. Determine the required length of concrete form tube by adding the height desired
above grade to the required 42-inch below grade pier depth.
Install conduits in the pier as needed for installation.
 Conduit is not supplied by GAI-Tronics.
 Consideration for power, Ethernet, telephone, 75-ohm RG6 cable, and any other customer wiring
determines the number and size of the conduit entries (see Figure 2 for typical conduit arrangements).
Figure 2. Sample conduit arrangements within tower
Concrete Form Construction
1. Place the 24-inch diameter concrete form tube on a bed of crushed stone in the excavated hole.
2. Place an 18-inch diameter by 38-inch long rebar reinforcement cage into the concrete form tube
before pouring the concrete.
The following materials are necessary to construct the reinforcement cage:
 Four 38-inch long #4 rebar rods
 Three 18-inch diameter #4 rebar stirrups
 Precut wire ties
To construct the reinforcement cage:
1. Tie a horizontal stirrup at the center of the four 38-inch rebar rods.
2. Tie the two remaining horizontal stirrups 18 inches above and below the center point (see Figure 3).
3. Place the cage on one-inch block spacers, centering the cage within the concrete form tube.
The top of the cage should be at least three inches below the top of the pier.

Maintenance
Repairing Surface Damage to Powder-Coated Towers
Scratch Repair
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.” Allow the area to dry. This
type of product is available at auto parts stores. Denatured alcohol can also be used.
3. Prepare the bare metal surface for painting by treating it with a phosphoric acid solution intended for
this purpose. Allow the area to dry.
4. Using a cotton swab or small brush, paint the prepared surface with an automotive enamel or oil base
polyurethane enamel such as Red Devil®or Rustoleum®. DO NOT USE Krylon-type paints.
Carefully blend the repair enamel into the powder coating at the edges.
NOTE:EXACT color matches may not be attainable.
Decal Repair
1. Use a sharp instrument, such as a razor blade, to loosen and lift a corner edge of the damaged decal.
2. Carefully peel back and remove the loosened decal.
3. Wipe the area clean with denatured alcohol. Allow the area to dry.
4. Prior to attaching a new decal, dampen the target area with a fine mist of water (fine spray from a
plant misting bottle is ideal).
5. Peel the backing from the replacement decal, leaving the decal’s front cover material attached, and
carefully align it with the target area.
6. With the cover material still attached, press the replacement decal in place, then squeegee any water
from under the new decal starting at the center and working toward the edges.
7. Peel off the front cover material, being careful not to tear or lift the decal. If the decal lifts as the
cover material is being removed, push down on the uncovered decal, and squeegee as necessary to
remove any large air bubbles; small air bubbles will disappear as the decal dries.
