Installation Instructions for 48XBRM Series

XBR (XTRA-BRITETM) LED DUAL-MODE Visual

Indicator

Description

The Catalog Series 48XBRM Visual Indicator is a UL and cUL
Listed signaling appliance rated for NEMA 4X applications.
The signals are suitable for indoor or outdoor (weatherproof)
installation and are available in AC and DC models as listed
above.

The 48XBRM Series XBR (XTRA-BRITETM) LED Dual-Mode
signals are well suited in high ambient noise level areas,
especially where ear protection must be worn. These LED
beacons are also ideal for high-vibration applications and
areas where long lamp life is advantageous. 48XBRM LED
beacons ship from the factory in steady-on mode and can
be readily transformed by changing the dipswitch setting to
65 FPM ashing mode.

The 48XBRM series signals can be mounted on 1/2" (13mm)
NPT conduit (indoor or outdoor) or direct surface mounted
(indoor only). For outdoor (weatherproof) installation, the
signals must be mounted with their lens dome facing directly
up. When installing indoors, these signals can be mounted
in any position.

PLC Compatibility

Signaling devices may be directly connected to PLC output
cards that meet the electrical input load specications listed
in Table 1. When signaling device ash rates are to be con­trolled via PLC, dip switch settings should be left in "steady­on" mode as originally shipped from the factory.

Installation

WARNING

To prevent electrical shock, ensure that power
is disconnected before installing the signals.

Install in accordance with the latest edition of the National
Electrical Code and local regulations. Install the signals

using one of the following applicable mounting procedures.

Conduit Mounting (Indoor or Outdoor) - Figure 1

WARNING

To prevent leakage and a potential shock
hazard, when mounting outdoors the signal
must be installed with the lens or dome facing
directly up.

1. Insert a small at blade screwdriver between the locking
mechanism and the lens. Gently push down and then
pry up, unseating the lens. Pull the lens up and off of
the signal mounting base, being careful not to damage
the internal circuit.

2. Setting the Flash Pattern: The 48XBRM Series Visual
Indicator is a dual-mode device supplied with a default
setting of steady-on. If ashing (65 fpm) mode is desired,
set dipswitch as shown in Figure 4. Refer to Figure 3 for
dipswitch location.

3. After setting the ash pattern, carefully place the lens
back on the unit and snap in place.

4. Route the signal's wire leads through 1/2" NPT conduit
(not supplied) and thread the conduit into the signal
mounting base.

5. Connect the eld wiring to the signal wire leads as
described in the Wiring Section.

NOTE: The installer should use suitable hardware

appropriate for the installation.

1. Insert a small at blade screwdriver between the locking
mechanism and the lens. Gently push down and then
pry up, unseating the lens. Pull the lens up and off of
the signal mounting base, being careful not to damage
the internal circuit.

2. Setting the Flash Pattern: The 48XBRM Series Visual
Indicator is supplied with a default setting of steady-on.
If ashing (65 fpm) is desired, set dipswitch as shown in
Figure 4.

3. Remove the two knockouts for mounting screws from
the signal base. Place the 3-3/4" (95mm) mounting
gasket provided in the direct surface mounting kit on
the mounting surface and mark the center of the three
holes in the gasket on the mounting surface. Remove
the gasket and drill a 3/8" (10mm) hole at each of the
marked positions.

4. Install the two rubber expansion plugs provided in the
hardware kit into the two outer holes in the mounting
surface.

governing codes, standards and
regulations.

5. Route the wire leads from the signal base through the
center hole in both the mounting gasket and surface. The
wiring should be run through an approved raceway or
conduit connected between the bottom of the signal base
and an approved junction box (not supplied). Bring wire
leads into the junction box. Refer to the signal's label for
voltage rating.

6. Align the outer holes in the mounting gasket with the
holes in the surface. Insert two screws with lockwashers
through the two outer holes in the signal base and align
the screws with the rubber expansion plugs as shown
in Figure 2. Press the signal base rmly against the
mounting surface and tighten the screws.

7. Carefully place the lens back on the unit and snap in
place.

8. Connect the eld wiring to the signal wire leads as
described in the Wiring Section.

Wiring

1. For AC models, use wire nuts (not supplied) and connect
the signal's black and white wire leads to the power
source wires. Polarity is not important.

2. For DC models, connect the signal's red wire to the
positive power source wire and connect the signal's black
wire to the negative power source using appropriate
connectors (not supplied). Polarity must be observed.
