57PLEDM Series Rotating Polaris LED Beacon
Installation Sheet

To install the beacon:

1. Remove the three screws from the bottom of the beacon
base (Figure 1).

2. Separate the beacon baseplate to gain access to the
wiring chamber.

Description

The 57PLEDM Series Rotating Polaris LED Beacon is UL and
cUL listed for general signaling use. The beacon is available in
120 VAC or multivoltage 12 VDC, 24 VAC, or 24 VDC models.
There are six lens colors to choose from, and a choice of black
or gray bases. The beacon utilizes high-power LED lights and
is suitable for indoor or outdoor use. The beacon is provided
with an enclosure rated for NEMA Type 4X and IP66.

The beacon is well suited for high ambient noise level areas,
especially where ear protection must be worn. It is also ideal
for high vibration applications and areas where LED
technology provides longer lamp life. The beacon features a
360-degree beam of light with 16 user-selectable flash or
rotation patterns, including Steady. The patterns are selected
by pressing the Edwards logo push button. The factory setting
is Light Burst pattern.

The beacon is designed to be mounted on 3/4 in. NPT conduit
(indoor or outdoor). To maintain the NEMA Type 4X and IP66
ratings for outdoor installation, the beacon must be mounted
with the dome facing directly up. When installing the beacon
indoors in dry environments, it can be mounted in any position.

Installation

Install the beacon in accordance with the applicable
requirements in the latest edition of the National Electrical
Code, Canadian Electrical Code, and local codes.

WARNINGS

 To prevent electrical shock, ensure that the power is

disconnected before installing the beacon.

 To prevent leakage and potential electrical shock, use

care when disassembling the beacon to prevent tearing of
the permanently affixed gaskets provided for the
environmental integrity and ratings.

 When mounting outdoors, the beacon must be installed

with the lens or dome facing directly up.

Note: The beacon mounts on a 3/4 in. NPT conduit pipe.

The female threaded entry is located on the bottom of the
base.

3. Install the baseplate on the conduit. Wrench-tighten for a
leak free seal.

4. Route the field wiring from the appropriate power source
through the conduit, and then through the conduit
entrance in the baseplate.

5. Wire in accordance with “Wiring” below.

6. Place the connected wires inside the base and secure the
beacon base plate to the base using the screws provided
(Figure 1).

7. Apply power and verify proper operation.

Wiring

Wire the beacon in accordance with the applicable
requirements in the latest edition of the National Electrical
Code, Canadian Electrical Code, and local codes.

To wire the beacon for 120 VAC:

1. Using wire nuts (not supplied), connect the field wiring to
the beacon wiring.

2. Connect the beacon’s black lead to hot, the white lead to
neutral, and the green lead to ground.

To wire the beacon for 12 VDC:

1. Using wire nuts (not supplied), connect the field wiring to
the beacon wiring.

2. Connect the beacon’s red lead to positive (+), and the
black lead to negative (−).

Note: The beacon is designed to be conduit mounted.

To wire the beacon for 24 VAC/VDC:

1. Using wire nuts (not supplied), connect the field wiring to
the beacon wiring.

2. Connections depend on the voltage supply. Choose the
connections that match your power supply:

24 VAC: Connect the beacon’s black lead to hot, the red
lead to neutral, and the green lead to ground.

24 VDC: Connect the beacon’s red lead to positive (+),
and the black lead to negative (−).

Selecting the flash or rotation pattern

The beacon can be configured with one of 16 user-selectable
flash or rotation patterns using a push button (membrane
switch). The push button is located in the center of the
Edwards “shield logo” on the base of the beacon (Figure 1).

To select a flash or rotation pattern:

1. Press and hold the push button for one second to switch
to the next pattern in the sequence (Table 1).

2. Press and hold the push button for three seconds to set
the beacon back to the first pattern (Steady).

Maintenance

Lens and dome replacement

WARNING: Electrocution hazard. To prevent electrical shock,

disconnect the beacon from the supply circuit and allow five
minutes for stored energy to dissipate before disassembling.

Caution: Do not overtighten the screws or damage to the

dome may occur.

To replace the lens or the dome:

1. Remove the four screws from the dome and lens
assembly, and then remove the dome and lens as shown
in Figure 1.

2. Make sure the O-ring is in place around the base of the
unit, and replace the lens and dome.

3. Reinstall the four screws and tighten each firmly until the
gasket slightly compresses between the dome and the
screw head.

Cleaning

Caution: To prevent damage to the lens or dome, do not use

abrasive materials or cleaners.

Periodically clean the lens surface with a soft cloth and water
or a mild detergent solution to maintain optimum light visibility.
Ensure that the lens is completely dry before assembling the
beacon.
