94PLEDM Series Rotating
Polaris LED Beacon
Installation Sheet
Description
The 94PLEDM 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. The beacon is also ideal for high
vibration applications and areas where long lamp life is advantageous.
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.
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
Electrocution hazard. To prevent electrical shock, ensure that
power is disconnected before installing the beacon
Electrocution hazard. 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.
Electrocution hazard. To prevent leakage and potential electrical
shock when mounting outdoors, install the beacon with the lens or
dome facing directly up.
Note:
The beacon is designed to be conduit mounted.
To install the beacon:
1. Release the latch on the clamp ring and remove the ring holding
the protective dome to the signal base. Lift the dome straight up off
of the beacon base (Figure 1).
2. Loosen the three screws in the keyhole slots in the base of the
lens, turn the lens clockwise, and lift it off of the LED light source
support plate.
3. Remove the three screws holding the LED light source support
plate to the beacon base.
4. Gently grasp the LED tower and carefully lift the support plate off
of the beacon base.
Note:
The beacon mounts on a 3/4 in. NPT conduit pipe. The
female threaded entry is located on the bottom of the base.
5. Route the field wiring from the appropriate power source through
the conduit, and then through the conduit entrance hole in the
beacon base.
6. Install the base on the conduit. Wrench-tighten for a leak free seal.
7. Wire in accordance with “Wiring” below.
8. Place the connected wires inside the base and reassemble the
beacon (Figure 1).
9. Apply power and verify that the beacon operates properly.
Wiring
Wire this unit in accordance with all applicable local codes and
standards and the local authority having jurisdiction.
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, and the white lead to
neutral. Connect the beacon’s green lead to the grounding point
located in the signal base.
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 (−).
To wire the beacon for 24 VAC/VDC:
1. Connect the field wiring to the beacon wiring using wire nuts (not
supplied).
2. Connections depend on the voltage supply. Choose the
connections that match your power supply:
24 VAC: Connect the black lead to hot and the red lead to neutral.
24 VDC: Connect the red lead to positive (+), and the black lead to
negative (
−). Connect the green lead to the grounding point
located in the beacon base.
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
