CAUTION

Danger of sharp metallic edges. Can cause injury.

Take care when servicing unit to avoid accidental

contact with sharp edges.

Application

LC and LG Units -- Smoke detector will send a 24Vac

signal to the unit controller when smoke is sensed. The

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.

Installation

CAUTION

Before attempting to perform any service or mainte

nance, turn the electrical power to unit OFF at dis

connect switch.

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 1 for location of power board, supply air sensor and

return air sensor. See figure 2 to assemble the supply air

bracket.

Sampling tube installation

1 - Select the appropriate sampling tube.

Supply air sensor -- 36”

Return air sensor -- 18”

2 - Slide metal sampling tube onto the back side of the

sensor. When sensor is installed in return air

applications, slide plastic exhaust tube onto back

side of sensor. See figure 3.

NOTE - Plastic exhaust tube is NOT used in supply air

applications and should be discarded.

3 - Orient sampling tube so that holes point toward the

air stream.

KC, KG and KH Units

1 - Supply air smoke detector installations -- Route

harness wires across the top of the unit. Secure wires

to existing bundle and route from the control area to

the blower compartment as shown in figure 1. Take

care to secure wires away from other components.

2 - Locate and disconnect wires labeled 1 and 4 in

control area. See figure 4.

3 - Locate power harness which has three

quick-connect terminals on one end of harness.

Connect wires labeled 1 and 4 to terminals

disconnected in previous step. Connect wire labeled

GND from power harness to ground tab in unit.

Position J255 plug near P250 and P252 plugs. See

Figure 4.

4 - Secure power board to hinged panel using two

#8-32X1” screws. Route power board harness

behind hinged panel as shown in figure 5 using

provided insertion-type wire ties.

5 - Use two #8 - 32 X 1/2” screws to secure smoke

detector hinged panel to hinged panel mounting

bracket. See details A and B on figure 5.

6 - Use two #8 - 32 X 1/2” screws to secure panel holder

to left side of compressor wrapper.

7 - Use two #8 - 32 X 1/2” screws to secure hinged panel

assembly to control box.

8 - Secure P255, J250 and J252 harness ends to the

insertion-type wire tie located in the control box.

9 - Make jack/plug connections as shown in figure 6

when installing return air smoke detector only, figure

7 when installing supply air smoke detector only, and

figure 8 when installing both supply and return air

smoke detectors.

LC and LG Units

1 - Install power board and hinged panel in control box

as outlined in steps 4 through 7 in KC, KG and KH

wiring section. See figure 5.

Note - If a DDC control is factory-installed, the hinged

panel will already be in place. Discard panel provided in kit.

2 - Secure P255, J250 and J252 harness ends to the

insertion-type wire tie located in the control box. See

figure 9.

3 - Make jack/plug connections as shown in figure 10

when installing return air smoke detector only, figure

11 when installing supply air smoke detector only, and

figure 12 when installing both supply and return air

smoke detectors.

NOTE - Harness P252/P253 is factory-installed and

is located near the supply sensor and power board

hinged panel. Plugs are located in the unit near the

the sensor(s) and power board.

Test Magnet(s)

A test magnet is provided in a bag assembly with each

sensor. Remove the magnet from the bag assembly and

place it on a metal surface near the sensor. The magnet is

used during test procedures.

Maintenance and Test Procedure

Instructions

The sensor manufacturer's instructions, which are

provided with each sensor, outline information on

maintenance and test procedures. Place these

instructions in the literature pouch for future reference.
