Application
LG, LC, LH, and LD Units -- Smoke detector will send a
24Vac signal to the unit controller when smoke is sensed.
Unit controller default mode will de-energize unit.
KC, KG and KH Units -- Smoke detector will interrupt the
24Vac signal to the unit control circuit when smoke is
sensed. Unit will be de-energized.
Identify Harnesses
Three harnesses are provided in the single sensor kit and
two harnesses are provided in the dual sensor kit. Use
wire labels, length of harnesses and number and size of
connectors to determine appropriate harnesses used in
each application. Refer to figure 1 for 53W78 single
sensor kits and figure 2 for 54W79 dual sensor kits.
Installation
Turn the electrical power to unit OFF at disconnect switch.
WARNING
Improper installation, adjustment, alteration, ser
vice or maintenance can cause property damage,
personal injury or loss of life. Installation and ser
vice must be performed by a licensed professional
installer, service agency or the gas supplier.
WARNING
To prevent serious injury or death:
1.Lock-out/tag-out before performing maintenance.
2.If system power is required (e.g., smoke detector
maintenance), disable power to blower, remove fan
belt where applicable, and ensure all controllers and
thermostats are set to the “OFF” position before
performing maintenance.
3.Always keep hands, hair, clothing, jewelry, tools, etc.,
away from moving parts.
CAUTION
As with any mechanical equipment, contact with
sharp sheet metal edges can result in personal in
jury. Take care while handling this equipment and
wear gloves and protective clothing.

Installation - continued
Smoke detector sensor and power board installation
Use manufacturer's instructions provided with smoke
detector to install sensor(s) and power board. Refer to
figure 3 for location of power board, supply air sensor and
return air sensor on units with an economizer. For location
of return air sensor on units without an economizer, refer
to figure 4 for KC, KG and KH units, and figure 5 for LG,
LC, LH, and LD units.
Sampling tube installation
1 - Slide metal sampling tube onto the back side of the
sensor as shown in figure 6. When sensor is installed
in return air applications, slide plastic exhaust tube
onto back side of the sensor as shown in figure 6.
NOTE - Plastic exhaust tube is NOT used in
supply air applications and should be discarded.
2 - Orient sampling tube so that holes point toward the
air stream.

Wiring - KG/KC/KH Units
1 - Locate and disconnect pink wires labeled 95 and 96
in the control area above compressor. See figure 7.
2 - Connect wires labeled 95, 96 and TB1-C from the kit
harness to wires labeled 95, 96 and TB1-C in unit.
3 - Route harness wires to the top of the unit. Secure to
existing bundle of wires and route to control area
above compressor. See figure 8. Make sure wires are
secured away from other components.
4 - Make jack/plug connections as shown in figure 9
when installing return air smoke detector only, figure
10 when installing supply air smoke detector only,
and figure 11 when installing both supply and return
air smoke detectors. Refer to respective wiring
diagrams in figure 12, 13 and 14.
NOTE - In single-sensor applications, the wiring harness
is sized for return air applications. There will be excess
wiring in supply air applications. Gather excess wire and
secure away from other components.FIGURE 8
