DESCRIPTION

The COS360 360 °passive infrared (PIR) occupancy sensors turn lighting systems on and off based on occupancy and ambient light levels. The light level feature keeps lights from turning on if the ambient light level is sufficient.

The sensors can be configured to turn lighting on, and hold it on as long as the sensor detects occupancy. After no movement is detected for a specified Time the lights are switched off.

COVERAGE PATTERN

The COS360 COS360 provides a 360° coverage pattern, up to 1200 square feet. The coverage shown represents walking motion at a mounting height of 8 feet (See Figure 1 ).For building spaces with lower levels of activity or with obstacles and barriers, coverage size may decrease.

COVERAGE PATTERN

PLACEMENT GUIDELINES

Depending upon obstacles such as furniture or partitions, the area of coverage may be less or more than the sensing distances shown in the coverage pattem. This must be considered when planning the number of sensors and their placement. It is also recommended to place the sensor 4 to 6 feet away from air supply ducts as rapid air currents or the differences in temperatures may cause false activations.

Mount the sensor to the ceiling. The COS360 is designed for a ceiling height of about 8-10 feet. Mounting above or below this range will significantly affect the coverage patterns. Be aware that as you decrease the mounting height, you decrease the range and increase the sensitivity to smaller motions. Conversely, when you increase the height, you increase the range and decrease the sensitivity to smaller motions. At heights of more than 12-14 feet, you may start to significantly reduce sensitivity. As a general rule, each occupant should be able to clearly view the sensor.

Often the best location to install a COS360 in a dosed office is off-center (see Figure 2). Avoid placing a sensor directly in line with an open door through which it has a clear view out, as the sensor may detect people walking by.

Open Office Area Coverage:
To get complete coverage in an open office area, install multiple sensors so that there is an overlap with each adjacent sensor’s coverage area. See the Figure 3.

WIRING DIRECTIONS

WARNING: Turn off the power at the circuit breaker before installing Refer to the wire diagram of the sensor (see figure 4), and connect the wires of ceiling sensors as followed by using the wire nuts provided.

Connect the Hot wire of main power to the Black wire from the sensor.
Connect the Load wire to the Red wire from the sensor.
Connect the Neutral wire of Load and main power to the White wire from the sensor.
Connect the two Grey wires( 22AWG) to the terminals of the momentary switch. You can add a MANUAL SWITCH such as the YQDS-115M Momentary Switch to the sensor by connecting the Grey wires. (Step 4 is not neccessary if you don’t want to use the funtion of MANUAL ON/OFF )

LIGHT LEVEL ADJUSTMENT

Turn the potentiometer on the sensor to “-” if adequate ambient light exists. The output of sensor will be inhibited, and the load cannot be on; only when the ambient light is below a certain level will the sensor will automatically turn on. Therefore potentiometers must be adjusted in accordance with the location and the existing ambient light level. Turn the potentiometer on the sensor to “+”, regardless of the ambient light level. The load will be on as long as there are signals from occupancy.

Avoid mounting the sensor close to lighting fixtures.
Adjust during daylight hours when ambient light in the area is at desired level. Open the Front Cover and adjust the Light level.

MOUNTING

Using an Octagonal Junction Box

Pull the high voltage wires into the J-Box through the conduit knockout.
Connect the high voltage wires to the appropriate terminals on the sensor.
Loosen the appliance mounting screws attached to the J-Box.
Align the sensor in the J-Box so that the mounting screws on the box match the key holes on the sensors rear housing.
Push the sensor up into the J-Box and twist it so that the mounting screws are seated in the keyhole slots.
Tighten the two screws to secure the sensor to the J-Box.
Snap the front cover onto the sensor(see Figure 6)

MOUNTING

SENSOR ADJUSTMENT

Note: There is a 40· second warm-up period when power is first applied.

The sensors are factory preset to allow for quick installation in most applications.
Verificati_on of proper wiring or coverage, or customizing the sensor’s settings can be done using the following procedures. To make adjustments, open the Front Cover with a small screwdriver.

Sensor Test:

Refer to Figure 8 above

Ensure the PIR Activity is enabled: red LED flashes, and PIR Sensitivity is set to MAX (DIP switch 1 OFF).
Ensure the Time Delay is set for Test Mode
Ensure that the Light Level is at the maximum position.(see” LIGHT LEVEL ADJUSTMENT’)
Remain still. The red LED should not flash. The lights should turn off after 15 seconds. (If not, see “TROUBLESHOOTING.”)
Move about the coverage area. The lights should come on.
When testing and adjustment is complete, reset DIP Switches.Time Delay and Light Level to the desired settings, and replace the cover on the sensor.

DIP SWITCH SETTING

The COS360 has 2 DIP switches under the cover. They are used to set sensitivity and vacancy mode feature settings.

Sensitivity setting: DIP Switch 1

50% – sensor’s coverage is smaller, just about half of the widest range.
100% – the maximum range of sensor’s coverage is 1200 square feet( see “COVERAGE PATTERN”)

Vacancy Mode: DIP Switch 2

Manual On function is achieved by using a momentary switch, such as the YQDS115-M momentary switch. The switch connected to the two grey wires(22AWG). Each press the switch, the load will be reverted. The operation of the sensor connected to manual switch depends on the DIP switch 2 setting.

Enabled State: Turn the lights on manually .When motion is no longer detected in a selected time ,lights will change to OFF.When the selected lime expires, the sensor will change to ON automatically if motion is detected again in 30 seconds.

Disabled State: In this mode ,when motion is detected in the area ,lights turn on automatically; When motion is no longer detected, light remain ON for a selected time, when the selected time expires ,lights turn off automatically.

A manual switch provides the following additional functionality:

a. The load can be turned ON by manual switch activation and it stays on as long as occupancy is· detected. The sensor lime delay operates as programmed. When the load turns OFF due to lack of occupancy detection, the load can be turned ON again by occupancy detection or switch activation.
b.Turn the lights OFF manually when it is ON.

When the load is turned OFF manually, as long as the sensor continues to detect occupancy the load stays OFF. Selected time after the last occupancy detection, the lights stay off and the sensor reverts to the automatic-on mode.
When the load is turned OFF manually, pressing the switch again turns the load ON and the sensor reverts to the automatic-on mode.
Once the sensor returns to automatic-on mode, either the switch or occupancy detection can turn the load ON

TROUBLESHOOTING

WARNING: Turn off the power at the circuit breaker before installing/adjusting.

Lights do not tum on with occupancy, and the following condition exists:
PIR Activity LEO does not flash:

NOTE: When power is initially applied to the sensor, there is a warm-up period of up to 40 seconds before the LED is active.

Check that the circuit breaker has been turned back on.
Make sure that the PIR Sensitivity is set for Max (DIP switch 1 OFF).
Make sure the wire is connected right.

PIR Activity LED flashes:

If the sensor’s Light Level has been turned to”-“, the lights connected to the Light Level Output might be held Off because of the level of ambient light in the controlled area. To test whether the Light Level adjustment is the problem, cover the PIR lens and PIR Activity LED (see diagram) with your hand to see if the lights turn on. If the lights turn on, the Light Level setting was keeping the lights Off (see, “Sensor Adjustment” for readjustment).
Make sure the wire is connected right.

Lights do not tum off automatically:

The sensor may be experiencing activations from outside the controlled area or from some type of interference (see “Unwanted Sensor Activations” below).
Make sure the wire is connected right.

Unwanted Sensor Activations (LED flashes):
