51XBRF Series Flashing LED Signal
Installation Sheet
Description
The 51XBRF Series Flashing LED Signals are AC and DC
operated combination flashing LEDs with horns. They feature
optically designed polycarbonate lenses. These signals are
suitable for installation in a permanent outdoor or indoor
application. Their base allows direct surface mounting,
mounting on 1/2 in. NPT conduit, or mounting on a 4 in.
(102 mm) octagon box. A hardware kit is included with the
signals for direct surface mounting applications.
Replacement horns, flasher modules, and lenses are available
for the signals. Refer to the table at the end of these
instructions for details.
PLC compatibility
The electrical input load requirements for PLC compatible
signaling devices are listed in Table 1. Signaling devices may
be directly connected to output cards that meet the input load
requirements.

Installation
Install this unit in accordance with the latest edition of the
NFPA 70 National Electrical Code and local codes. Prior to
mounting the signal base, the signal must be removed from the
base. The base can be mounted using one of the following
methods:
• Direct surface mount
• Mounted on 1/2 in. NPT conduit
• Mounted on a 4 in. octagon box
WARNINGS
• To prevent electrical shock, ensure that power is
disconnected before installing the signals.
• To prevent leakage and potential electrical shock, use
care when disassembling the signal to prevent tearing of
the permanently affixed gaskets provided for
weatherproofing.
To remove the signal from the base:
1. Remove the screw in the clamp ring, and then remove the
ring. See Figure 1.
2. Carefully lift the lens/lamp assembly off the base.
3. Install the signal base using one of the following mounting
procedures.
