COS-L SERIES

CONNECTING THE LOW VOLTAGE

+24VDC (RED) RED wire from TRP
Common (BLACK) BLACK wire from TRP
Control Out (BLUE) BLUE wire from TRP

1. Turn power off at the electrical panel.

2. Connect the sensor +24VDC wire to power pack red wire. Connect the sensor common to power pack
black wire. Connect the sensor control wire to the power pack blue wire.

3. Remove sensor cover and mount the sensor to ceiling tile or electrical box using 2 mounting screws

provided.

4. Turn power on at the electrical panel.

5. Program only if custom setting is desired. Refer to push button chart and follow the instructions.

6. Place cover on sensor.

COVERAGE PATTERN: COS-L

The COS-L provides a circular pattern of 1200 square feet. The diagram shows walking motion
detection with the lighter bands. Small motion detection is shown with darker bands. Barriers
within the space that block line-of-sight to sensor detection will decrease coverage area.

COVERAGE PATTERN: COS-LU

The COS-LU provides a circular pattern of 900 square feet. The diagram shows walking motion
detection. Small motion detection is closer to the sensor.

DESCRIPTION

The COS-L Series is a low voltage powered occupancy sensor. It turns lighting
systems on and off based on occupancy. The sensor is configured to turn
lighting on, and hold it on as long as the sensor detects people moving in the
room. After no movement is detected for a user specified set time (5 to 30
minutes), the lights are switched off. The COS-L Series is designed for lower
mouting heights found in office bulidings.

An optional energy savings feature is included. The "walk-through" mode
shortens turn-off timing to 3 minutes when no activity is detected after 30
seconds.

The COS-L Series operates on 24V DC supplied by a Tork TRP-24I or TRP-24B
Power Pack.

COVERAGE – 1200 sq. ft. PIR

PLACEMENT GUIDELINES

The COS-L Series is designed for ceiling mounting at a height of about 8-10 feet. Mounting
the sensor at greater heights decreases the sensitivity to motion. Lower mounting height will
also decrease the range.

The sensor should be installed with a visually unobstructed view of the workspace normally
occupied. If the occupant cannot see the sensor from their normal work position, the sensor
will not be able to detect their presence. File cabinets, doors, partitions, and walls are typical
types of obstructions.

Place the sensor no closer than 5 feet to an HVAC air duct. COS-L2T: Remove all hanging
decorations from ceiling that HVAC air ducts might cause movement. If decoration movement
trips sensor, set to PIR only for initial trigger (function 10).*

For enclosed offices, avoid sensor placement close to a doorway. Placing the sensor offset
from the center and away from the door is recommended. COS-L2T: If hallway movement
trips sensor set to PIR only for initial trigger (function 10).*

COVERAGE PATTERN: COS-L2T

The COS-L2T provides a circular pattern of 1200 square feet. The diagram shows walking motion
detection with the lighter bands. Small motion detection is shown with darker bands. Barriers
within the space that block line-of-sight to sensor detection will decrease coverage area.

CAUTION

We recommend that installation be made by a liscensed electrician.

Before wiring and servicing, power to this unit and the

equipment it controls must be turned off at the main panel. Connect in

accordance with national and local electrical codes.

COS-L SERIES WIRING INSTRUCTIONS

Tork recommends using the TRP-24I transformer relay pack to supply power
for six (6) COS-L Series sensors. Additional TRP-24I may be used if more
sensors are required.

Open office designs encourage placement of the sensors to allow small area coverage into
each cubicle.

*Model COS-L2T only.

FOUR & OUT THE DOOR SETTINGS CHANGE

To change a program feature:

PREP: Review the function to see the function number, current setting, and new setting that is

to be entered.

1. START program mode:

a. Press the button 5 times consecutively. (The LED flashes with each press)
NOTE: After the 5th button press the LED will stay on. The sensor is now in Program Mode.

2. CHOOSE the function:

a. Press the button "X" number of times to enter a function to change. (The LED
flashes with each press)
NOTE: When the button presses stop the sensor will then flash back the current setting for
that function. (The sensor will do this 10 times and then go back to run mode if nothing is
processed with prior settings)

3. CHANGE Function:

a. Press the button the number of times for the new setting. (The LED flashes
with each press)
NOTE: When the button presses stop, the sensor will then flash back the new setting for
that function. (The sensor will do this 10 times and then go back to run mode if nothing is
pressed and the new setting will not be saved)

4. SAVE Setting

a. Press and hold the button until the LED stays on, then release the button.
b. Press the button 5 times to lock in the setting. (The LED flashes with each press)
After the 5th press the sensor will go back to run mode with the new setting active.
