g. Mount the base as instructed below.
2. Mount the base using one of the following methods:
NOTE: For indoor applications, the base may be panel
mounted or conduit mounted. For NEMA3R, 4X, and outdoor
applications, it is recommended that the unit be conduit
mounted vertically facing up using either the Cat. No. 102TBS
or Cat. No. 102PMBS base.
a. Cat. No. 102TBS Install base on 3/4" (19 mm)
conduit (not supplied). Pull field wiring through
conduit entrance hole.
b. Cat. No. 102PMBS Install base on 3/4" (19 mm)
conduit (not supplied). Pull field wiring through
conduit entrance hole.
c. Cat. No. 102DMBS Using the supplied mounting
gasket as a template, punch the four mounting holes.
Punch the wiring clearance hole in the mounting
surface to be sufficiently larger than that in the gasket
to ensure the wiring insulation is protected from
abrasion by the gasket (without interfering with the
mounting screw holes), or provide other appropriate
wire insulation abrasion protection as needed. Mount
the base to the surface using the (2) screws
(supplied).
3. Connect field wiring.
a. Cat. No. 102TBS Connect field wiring to the terminal
block as shown in Figure 1.
b. Cat. No. 102PMBS or Cat. No. 102DMBS Using
wire nuts, connect 18" (457 mm) wire leads to field
wiring. The six wire leads are marked as follows:
Neutral, 1 Bottom, 2, 3, 4 & 5. 1 Bottom denotes the
lead for the bottom-most signal in the stack.
c. If using the optional Cat. No. 102SIGST single tone
module or Cat No. 102SIGMT multi-tone module,
connect additional field wiring to the terminal block
mounted on the signal assembly as shown in Figure
2.
NOTE: The tone module may be wired to sound
independently or in conjunction with a light signal.
(1) To sound tone module independently, connect to
separate hot lead.
(2) To sound tone module with a particular light,
connect horn hot terminal to selected light
terminal on Cat. 102TBS terminal block.
4. Assemble the stackable beacon lighting system (Figure 3).
a. Pull the captive key in the lens module into the "out"
position.
b. Place the first lens module on top of the base.
c. Push in the captive key to secure the lens module.
WARNING: To prevent leakage, ensure the magnifier ring on
the lens cover and the magnifier ring on the lens module are
aligned (Figure 3).
d. Insert the appropriate light source into board grooves
at bottom of lens module, ensuring that the four
prongs on the PC board are aligned with the plug
located in the back of the lens assembly.
NOTE: When using LED light sources, ensure that the color
of the LED light source and the lens assembly match.
e. Place the lens assembly cover on the front of the lens
module and secure using two captive screws.
f. Repeat steps a through e for any remaining modules
(up to 5).
g. Once the last module has been assembled, place the
cap on top and secure the cap with the captive screw.
WARNING: To prevent electrical shock, disconnect power to
all modules. Wait 5 minutes for stored energy in strobe
modules to dissipate before working on unit.
5. Apply power to the unit and verify proper operation.
Maintenance
Light Source Replacement
1. Loosen captive screws and remove cover of affected lens
module.
2. Remove the light source assembly from the lens module.
3. Install new light source assembly ensuring that the four
prongs on the PC board are aligned with the plug located
in the back of the lens module.
WARNING: To prevent leakage, ensure the magnifier ring on
the lens cover and the magnifier ring on the lens module are
aligned (Figure 3).
4. Replace lens cover and secure using two captive screws.
Cleaning
The lens surfaces should be periodically dusted and cleaned
with a dry soft clean cloth to maintain optimum light visibility. If
necessary, the outside of the lens may be cleaned with water
and a mild detergent on a well rung-out, soft, clean cloth.
