General Information
The catalog series 94DDV2(*)-G1 Adaptabeacon signal is a diode polarized, UL listed strobe light in a NEMA 4X Enclosure.
It is designed for applications requiring electrical supervision of
field wiring (Figure 1) and for use in the following hazardous
locations:
Class Division Group Operating Temp. Code
I 2 A,B,C,D T3 (392F, 200C)
II 2 F,G T6 (185F, 85C)
III T6 (185F, 85C)
The signal is suitable for indoor or outdoor (weatherproof) installation.
Replacement parts for the signal are available. Refer to the "Replacement Parts" section for details.
Electrical Specifications
Rated Voltage ....................................................... 24V DC
Current ................................................................ 1.2 Amps
Installation
Install in accordance with the latest edition of the National Electrical Code and local regulations.
1. (Figure 2) 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 signal base. Loosen the three
screws in the keyhole slots located in the base of the lens.
Turn the lens clockwise and lift it off of the strobe tube support
plate. Remove the three screws holding the strobe tube
support plate to the signal base; grasp the socket on the strobe
tube support plate. Do not touch the glass tube. Carefully
lift the support plate off of the signal base.
2. Mount the 94DDV2(*)-G1 to 3/4" (19 mm) NPT conduit (not
supplied).
WARNING
To prevent leakage and a potential electrical shoc k
hazard, when installing outdoor s, the signal m ust
be mounted with the lens facing directl y up.
a. Route the field wiring from the power source through
the conduit and through the conduit entrance hole in the
signal base (Figure 2).
b. Install the signal base on the conduit (Figure 2).
3. For non-supervised circuits, connect field wiring to signal
wiring using wire nuts (not supplied). Connect the signal's
two red positive (+) wire leads to the positive power source
wire and connect the signal's two white (-) wire leads to the
negative power source wire.
WARNING
To reduce the risks of igniting hazar dous
atmospheres and of electrical shock, ensure that
power is disconnected bef ore installing the signal.
CAUTIONS
To prevent damage to the strobe tube, lift the lens
straight up and off of the signal.
To prevent damage to the strobe tube, handle the
tube only by the base.
4. For supervised circuits, connect field wiring to signal wiring
using wire nuts (not supplied). Connect the signal's two red
positive (+) wire leads and two white (-) wire leads to the
supervised circuit in accordance with Figure 1.
5. Place the connected wires inside the signal base and
reassemble the signal.
6. Turn on the power and verify that the signal operates properly.

Maintenance
Replacement Parts
WARNING
To reduce the risks of igniting hazar dous
atmospheres and of electrical shock, ensure that
power is disconnected before installing the signal.
Do not connect power until installation is complete
and unit is tightly assembled and secured.
Cleaning
CAUTION
To prevent damage to the lens, do not use abrasive
materials or cleaners.
The signal's lens and dome should be periodically cleaned to
maintain optimum light visibility. These items may be cleaned
with a soft cloth or sponge using water or a mild detergent solution. Make sure the lens and dome are completely dry before
reassembly.
Strobe Tube Replacement
CAUTIONS
To prevent damage to the strobe tube, lift the lens
straight up and off of the signal.

To prevent damage to the strobe tube, handle the
tube only by the base.
Refer to the "Replacement Parts" section for the required strobe
tube.
1. (Figure 2) Disconnect the power and wait five minutes for
stored energy to dissipate. Lift the dome off of the signal
base. Loosen the three screws in the keyhole slots in the
base of the lens. Turn the lens clockwise and lift it straight
up and off the strobe tube support plate. Remove the three
screws holding the strobe tube support plate to the signal
base. Carefully lift the support plate off of the signal base.
2. Remove the tube from the socket by grasping the base of the
strobe tube and pulling firmly or by carefully prying between
the strobe tube base and the socket.
3. Install the new strobe tube by aligning the key on the strobe
tube base with the slot in the socket and then pressing the
strobe tube base into the socket.
4. Reassemble the signal.
5. Apply power and verify that the strobe operates.
