NOTE: Enclose wiring within an approved
raceway interconnecting the appliance
and junction box in accordance with
governing codes, standards and
regulations.
Direct Surface Mounting (Indoor Only) - Figure 2
NOTE: The installer should use suitable hardware
appropriate for the installation.
1. Insert a small flat 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 flashing (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.
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 firmly against the
mounting surface and tighten the screws.
7. Carefully place the lens back on the unit and snap in
place.
8. Connect the field 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.
