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.

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