A 4-S junction box can be used with a 3" mud-ring when local building codes mandate that low voltage connections be contained in a

junction box. Otherwise a 3" mud-ring or the provided ceiling attachment ring can be used.

IMPORTANT: If the lens will be masked, the junction box or mud ring may need to be positioned so that the mask is oriented properly

when the sensor is installed (see Masking).

Cut a hole in the ceiling tile–if using a:

• Ceiling attachment ring (provided)–cut about 2-3/4" to 3" in diameter.

• 3" mud ring–cut the hole to accommodate.

To assemble the sensor:

1. If using the ceiling attachment ring, bend the securing straps up so the sensor housing

can be inserted, and attach it to the sensor with the provided screws.

2. Attach the mask, if using, into the lens recess and onto the securing pins of the cover.

3. Attach the cover to the rear housing–align tabs on inside of cover to notches on outside

perimeter of rear housing, place cover on sensor, and twist clockwise to lock.

4. Insert the assembled sensor into the ceiling hole, and if using the mask, turn the

sensor so that the unmasked part of the lens is toward and centered on the area to be covered.

5. Bend the ceiling attachment ring straps behind the hole to secure (or attach sensor to mud ring with screws).

Masking

An insert (mask) is supplied to allow elimination of coverage in unwanted areas.

The mask is cut as needed and mounted onto anchor pins in the sensor's cover.

IMPORTANT: Do not use the mask if full coverage is desired.

IMPORTANT: Before securing the sensor in the mounting location, the assembled sensor must be turned so the unmasked portion of

the lens faces the coverage area (the blue masked area is

visible through the lens).

IMPORTANT: For an already installed sensor–If the

sensor CANNOT be turned, then the mask must be cut so

that when installed, it will be oriented correctly (note the

location of the securing pins in the cover and note that

the cover turns as it locks into position).

NOTE: Cut mask into sections for desired coverage,

shown below.

NOTE: Connect 24VAC or +24VDC Supply to the RED and Return to

the BLACK wire from the sensor.

Isolated Relay: (Rated for 1A @24VDC or 24VAC).

Connect the wires necessary to the application that requires this output.

GREEN (Normally Closed) - Open when occupancy is detected.

ORANGE (Common) - Must be used for proper operation.

YELLOW (Normally Open) - Closed when occupancy is detected.

The sensor comes factory preset and ready for operation.

If testing of operation is desired:

• Remove the sensor's cover (twist).

• Refer to the DIP switch settings chart below for switch configurations.

• Make sure that office furniture and fixtures are in place.

1. Confirm the Service DIP switch is set to Normal (DIP Switch #4 to OFF).

2. Restore power and turn on the system interfacing with the Isolated Relay.

• There is a one minute warm-up when power is initially restored to the sensor before the sensor works properly.

3. Set Time Delay to minimum: DIP Switches #1 and 2 to ON (30 seconds).

4. Set Sensitivity to maximum: DIP Switch #3 to ON.

5. Replace the sensor's cover.

6. Move away from sensor and be still. The sensor should time-out after 30 seconds, and the isolated relay contacts should return to

their "normal" condition (Normally Open or Closed), see Wiring Directions diagram.

NOTE: If the sensor does not time-out or the isolated relay does not return to its normal condition, move farther away or out of

sight of the sensor, or see Unwanted Sensor Activations under Troubleshooting.

7. Reset the Time Delay to the desired delay (DIP Switches #1 and 2).
