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.

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.

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 .

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.
