Signals
Description
The Catalog Series 51(*)-E1 and 51(*)-G1 Adaptabeacon signals
are dc operated, weatherproof, combination flashing lights with
horns. They feature optically designed polycarbonate lenses.
These signals are suitable for installation on a vehicle, or perma-
nent outdoor or indoor installation. Their base allows direct sur-
face mounting, mounting on 1/2" (13 mm) NPT conduit, or mount-
ing on a 4" (102 mm) octagon box. A hardware kit is included
with the signals for direct surface mounting applications.
Specifications
1. Remove the base from the signal using the following
procedure:
See Figure 1. Remove the screw in the clamp ring, remove
the ring, and lift the lens/lamp assembly off the base. Now,
install the base as described in Step 2.
2. The signal can be direct surface mounted, mounted on 1/2"
(13 mm) NPT conduit, or mounted on a 4" (102 mm) octagon
box. Install the signal base using one of the following
mounting procedures.
Direct Surface Mounting
a. Remove the two knockouts for mounting screws from
the signal base bottom. (See Figure 1 for the location of
knockouts.)
b. Refer to Figure 2 before continuing the mounting
procedure. Then place the gasket provided in the
hardware kit on the mounting surface, and mark the
center of the three holes in the gasket on the surface.
Remove the gasket and drill a 3/8" (9.5 mm) hole at
each of the marked positions.
c. Install the two rubber expansion plugs provided in the
hardware kit into the two outer holes in the mounting
surface as indicated in Figure 2.
d. Route the field wiring from the required power source
for the signal (refer to its label for the voltage rating)
through the center holes in the mounting surface, gasket
and base.
e. Align the holes in the gasket with the holes in the base.
Insert the two screws with lockwashers provided in the
hardware kit through the mounting holes inside the base
and align the screws with the rubber expansion plugs as
shown in Figure 2. Press the base firmly against the
mounting surface and tighten the screws. Now proceed
to step 3 for wiring connections.
NOTE: For direct surface mounting, the 51 series signals may
be installed in any position.
Mounting on 1/2" (13 mm) NPT Conduit
Replacement lamps, horns, flasher modules and lenses are avail-
able for the signals. Refer to the table at the end of these instruc-
tions for details.
PLC Compatibility
The electrical input load requirements for PLC compatible sig-
naling devices are listed in Table 1. Signaling devices may be
directly connected to output cards that meet these input load re-
quirements.
Installation
Install in accordance with the latest edition of the National Elec-
trical Code and local codes.
WARNINGS
To prevent electrical shock, ensure that power is
disconnected before installing the signal.
To prevent leakage and potential electrical shock,
use care when disassembling the signal to prevent
tearing of the permanently affixed gaskets provided
for weatherproofing.
