Brand: EDWARDS

Model: 106DEXSTC-FJ Series

Type: Installation guide

EDWARDS 106DEXSTC-FJ Series is a strobe light intended for indoor use in fire alarm systems and other applications requiring electrical supervision of signaling circuit field wiring. When assembled, the device is UL listed for use in various hazardous locations.

The strobe light has a clear lens, flashes at a rate of approximately 65 times per minute, and has a rated light output of 55 cd ceiling and 35 cd in other directions. It can operate within a voltage range of 20-30V DC and has special application voltage range of 20-30V DC. The strobe light requires supply wire temperature ratings of 75°C when the ambient temperature is 40°C, 90°C when the ambient temperature is 55°C, and 105°C when the ambient temperature is 65°C.

Installation Instructions for 106DEXST-FJ AdaptaBeacon

Strobe Lights for Use in Hazardous Locations

DescriptionDescription

Description

The 106DEXSTC-FJ (clear lens only) AdaptaBeacons are in-

rush 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.

WARNING

To reduce the risk of ignition of hazardous atmo-

spheres and shock, do not apply power to the unit

until installation has been completed and unit is

tightly assembled and secured.

InstallationInstallation

Installation

Install this unit in accordance with the applicable require-

ments in the latest edition of the National Electrical Code.

WARNING

To reduce the risk of ignition of hazardous atmo-

spheres and shock, keep assembly tightly closed

when circuits are energized.

box (not supplied). Secure 3/4" (19 mm) NPT

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 Table 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.

NOTE: For non-fire alarm use without field wire supervision installer can tie the two red leads together and

tie the two black leads together.

For strobe tube replacement, disconnect from the supply

circuit and allow five (5) minutes for stored energy to dis-

sipate 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.

Maintenance

CAUTION

When replacing the strobe tube, do not handle the

tube. Hold the strobe tube only by its base to pre-

vent 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.

WARNING

To reduce the risk of ignition of hazardous atmo-

spheres and shock, keep assembly tightly closed

when circuits are energized.

To reduce the risk of ignition of hazardous atmo-

spheres and shock, disconnect from the supply and

circuit and allow five (5) minutes for stored energy to

dissipate before disassembling the unit.
