Mount Bracket/Amplifi er to Location
1. Position the bracket/amplifi er in the desired orientation.
2. Secure bracket/amplifi er to location.
REMOTE MOUNT AMPLIFIER/DETECTOR WIRING
Remote Mount Amplifi er
The remote mount amplifi er has three chambers and fi ve
wire ports. The Junction Box and Connections Chambers
and wiring ports provide amplifi er openings for wire, conduit,
tool and hand access to amplifi er terminal blocks. Detector
to amplifi er wires connect in the Junction Box Chamber.
Amplifi er AC power and customer signal wires attach in the
Connections Chamber.
The Display/Programming Chamber provides access to
fuses and circuit boards. They are discussed later.
(Refer to the Remote Mount Wiring Diagram on page 11.)
Detector Junction Box
The Detector Junction Box has one chamber and two wire
ports. The junction box, chamber and wiring ports provide
openings for wire, conduit, tool and hand access to terminal
blocks. Detector to remote mount amplifi er electrode and
coil wires connect to the detector through the chamber wire
ports.
· Suitably trained personnel shall perform all
installation or repair procedures.
· Disconnect power to the unit before attempting any
installation or maintenance.
· Do not bundle or route signal wires with power
wires.
· Use proper conduit, connections and supplied
cables in all wiring procedures.
· Observe all local applicable electrical codes when
wiring any equipment.
Electrode and Coil Wiring From Detector Junction Box to
Remote Mount Amplifi er Junction Box
A remote mount unit requires electrode and coil cables,
from the detector junction box to the amplifi er junction box,
be enclosed in properly rated conduit. Use conduit fi ttings
(not supplied) that are rated for Class I, Div 1 hazardous
locations.
Failure to use proper conduit fi ttings rated for Class I,
Div 1 hazardous locations, invalidates the FM rating and
any warranties, expressed or implied, for this equipment.
1. Lay out the cable and conduit between the Detector
Junction Box and the Amplifi er Junction Box. Use Belden
#9155 cable or equivalent for electrodes. Use Belden
#8770 cable or equivalent for coils.
2. Run cables through the conduit, between Detector
Junction Box and Amplifi er Junction Box.
3. Place four Nema 4X, 1/2 inch NPT fi ttings on conduit.
4. Remove the four junction box wire port screws, two on
each junction box.
Electrode Wiring in Detector Junction Box
To connect electrode wires in the Detector Junction Box:
1. Unscrew the Detector chamber cover. If necessary, use a
strap wrench.
2. Remove the protective plastic cover to access the
terminal block screws.
