DescriptionDescription

The 106DEXSTC-FJ (clear lens only) AdaptaBeacons are in­rush current limited strobe lights that are UL1971 listed as
Special Application 20-30V DC Signaling Appliances for
the Hearing Impaired, with CSFM Listing as well. They
are intended for indoor use in UL listed compatible fire
alarm systems and other applications requiring electrical
supervision of signaling circuit field wiring. The strobe
flashes a 360-degree beam of light approximately 65 times
per minute with a 55 cd ceiling light output (35 cd other)
per Figure 5.

When assembled in accordance with these instructions,
these 106DEX Series visual strobe signals are UL listed for
use in Class I, Division 1, Group C and D, Class I, Division 2,
Group A, B, C and D, Class II, Division 1, Group E, F and G,
Class II, Division 2, Group F and G, and Class III Division 1
and 2 hazardous locations with Operating Temperature
Codes per the following chart.

threaded conduit (not supplied) to the box. Install
the hood on the conduit. Proceed to step 2.

b. Ceiling Mount Models (Figures 2 and 4):

Unscrew the globe assembly from the ceiling
mount box. Mount the ceiling box using
appropriate hardware (not supplied) suitable for
the mounting surface. Proceed to step 2.

c. Bracket Mount Models (Figures 3 and 4):

Unscrew the globe assembly from the wall bracket.
Install the mounting bracket using appropriate
hardware (not supplied) for the mounting surface.
Pull the field wiring through the mounting
bracket. Proceed to step 2.

2. Extend the required power source wiring down
through the mounting hood. See T able 4 for required
supply wire temperature ratings.

3. A ground screw is provided in the wiring compartment
for attachment of field earth ground wire.

4. Connect the two red positive (+) and two black
negative (-) wire leads to the supervised circuit in
accordance with Figure 4.

5. Install the fixture on the mounting hood, bracket or
box as applicable.

WARNING

To reduce the risk of ignition of hazardous atmo­spheres and shock, keep assembly tightly closed
when circuits are energized.

Install this unit in accordance with the applicable require-

6. Apply power to the unit and ensure proper function.

ments in the latest edition of the National Electrical Code.

WARNING

To reduce the risk of ignition of hazardous atmo­spheres and shock, do not apply power to the unit
until installation has been completed and unit is
tightly assembled and secured.

NOTE: This unit must be mounted vertically with the

globe assembly vertically facing down in
Hearing Impaired Applications.

1. Mount using the following applicable method.
a. Pendant Mount Models (Figures 1 and 4):

Unscrew the globe assembly from the mounting
hood and set aside. Install explosion-proof hanger

WARNING

To reduce the risk of ignition of hazardous atmo­spheres and shock, keep assembly tightly closed
when circuits are energized.

To reduce the risk of ignition of hazardous atmo­spheres and shock, disconnect from the supply and
circuit and allow five (5) minutes for stored energy to
dissipate before disassembling the unit.

For strobe tube replacement, disconnect from the supply
circuit and allow five (5) minutes for stored energy to dis­sipate before starting work or disassembly (Figure 6).

1. Loosen the (3) guard screws and remove the guard.

2. Loosen the globe and ring assembly set screw. Insert
a suitable tool into the notches in the globe and ring
assembly and loosen the assembly by prying in a
counterclockwise direction. Remove the ring and
globe assembly .

(198.12mm)

CAUTION

When replacing the strobe tube, do not handle the
tube. Hold the strobe tube only by its base to pre­vent damage to the tube.

3. Refer to Table 2 for the correct replacement catalog
number and replace the necessary part.

4. To replace, simply screw the unit on until it seats firmly
onto its gasket. Tighten the unit another 1/8 to 1/4
turn. Tighten the setscrew .

5. Reinstall the guard, where applicable, and secure using
the three supplied screws.

6. After the unit is assembled, apply power and make
sure the unit functions properly .

NOTE: DC polarity of circuit shown in supervisory state (signal inactive). Circuit polarity to reverse to activate signal.
Electrical supervision requires wire run to be broken at each device.
Device for constant input voltage. Do not connect to “coded” or pulsating voltage.
