Edwards Signaling 125 Class Halogen User Manual

Installation Instructions for 125 Class Beacons,

HALOGEN Models

Description

Edwards 125 Class halogen beacons are UL and cUL listed
signaling appliances rated for NEMA 4X applications. Two
versions of 125 Class Halogen Beacons are available: Flash­ing (125HALF) and Steady-On (125HALS). Both versions
can be either surface or conduit mounted.

A protective wire guard, Cat. No. 125GRD, is available.

2. Wire the beacon as follows:

a. For AC models, use wire nuts (not supplied) and

connect the signal's black and white wire leads to the
power source wires as shown in Figure 1. Polarity
is not relevant.

b. For DC models, connect the signal's red wire to the

positive power source wire and connect the signal's
black wire to the negative power source wire using
wire nuts (not supplied). Polarity must be observed.
Refer to Figure 1.

3. Thread the conduit onto the base of the signal.

WARNINGS

To avoid risk of injury, install lens before
energizing the unit.

To avoid the risk of injury, do not remove or
insert lamp when unit is energized.

4. Turn on power and verify that the signal operates
properly.

Installation

WARNING

To prevent electrical shock, ensure that
power is turned off before installing the
signal.

Conduit Mounting (Figure 1)

1. Thread the 18" (45.7 cm) signal wire leads through either
1/2" or 3/4" conduit into an approved conduit outlet box.
(Product is supplied with a double threaded - 1/2" internal
and 3/4" external - conduit hub.)

Note: When panel mounting the beacon, the surface and

construction details of the panel must be taken into
consideration in order to ensure that the integrity
of the outdoor, NEMA 4X rating is fully maintained.
Installer should evaluate.

1. Place the mounting gasket (supplied) over the hole in
the panel and route the signal wires through the gasket
and the hole in the panel.

2. Insert the base through the hole in the panel and screw
the locking nut (supplied), with the raised locking edge
facing the mounting surface, onto the base to secure the
beacon.

3. Wire the beacon as follows:

a. For AC models, use wire nuts (not supplied) and

connect the signal's black and white wire leads to the
power source wires as shown in Figure 2. Polarity
is not relevant.

b. For DC models, connect the signal's red wire to the

positive power source wire and connect the signal's
black wire to the negative power source wire using
wire nuts (not supplied). Polarity must be observed.
Refer to Figure 2.

4. Turn on power and verify that the signal operates
properly.

Maintenance

WARNINGS

To avoid risk of injury, install lens before
energizing the unit.

Lamp Replacement

1. Conduit Mounted Modules: Disconnect wiring and, if
necessary, unscrew base from conduit (Figure 1).

Panel Mounted Modules: Disconnect wiring and

remove locking nut that secures the base to the panel
(Figure 2).

To avoid the risk of injury, do not start any
maintenance when unit is energized.

To prevent electrical shock, disconnect all
power and wait ve (5) minutes for stored
energy in strobe modules to dissipate
before starting work on unit.

Cleaning

Disconnect power before cleaning. The module lens exterior
surfaces should be periodically cleaned with a soft clean
cloth using water and a mild detergent to maintain optimum
light visibility.

Figure 1. Conduit Mounting (3/4" Shown)

2. Remove (4) screws that secure the lens to the base from
bottom of base (Figure 3) and remove lens.

3. Replace halogen lamp as follows (Figure 3):

a. Grasp the metal base of the halogen lamp and push

the lamp down while turning counterclockwise. Then,
pull the lamp directly upward to remove from the

socket.

b. Grasp the new halogen lamp by its base and insert

in the socket. Push down and rotate clockwise to
lock in place.

CAUTION: Do not touch glass surface of lamp at

any time.)

4. Reattach lens to base and fasten with screws removed
in step 2.
