PASSIVE INFRARED SENSING IN WAREHOUSES
INSTALLATION & MOUNTING INSTRUCTIONS
ADJUSTABLE CONTROL PARAMETERS
IMPORTANT START-UP INFORMATION
Warehouses can have ambient temperature variations that may
affect sensor detection and coverage areas. High temperatures at
the covered area (above 80°F) reduce the detection zone of the
sensor. Consider adding more sensors if the ambient temperatures
are expected to be high. Additionally, high floor level temperature
may require larger movement for detection. In some cases,sensors
mounted above 40’ may only detect large heat signatures such as
forklift trucks.
1. Determine the mounting location appropriate to the features of
the sensor and the coverage area.
2. Avoid placing the sensor where the edge of the fixture, shelving
or other obstructions may block the sensor’s line of sight. Mount
the sensor below the edge of the fixture and away from the
lamps so that the heat from the lamps does not affect the sensor.
3. If using the hold-off daylighting light level feature, avoid
mounting in location where adjacent fixtures contribute to the
photocell measurement.
4. If using snap-in mounting hardware, select washers to
accommodate fixture wall thicknesses according to the chart
below.
5. Assemble any necessary mounting accessories and attach them
to the sensor, making sure that the flying leads from the power
module are accessible.
6. Connect the line voltage and load wires to the sensor leads as
shown in the Wiring Diagram (see Figure 4) .
• Do not allow bare wire to show.
• Make sure all connections are secure.
7. Restore power from the circuit breaker.
SETTING TIME DELAY
Trimpot
1. Adjust the trimpot to the desired time delay (hard stop settings:
5, 10, 15, 20, 30 minutes; default 15 minutes).
WSREM Remote
1. Aim the remote at the IR receiver on the sensor
2. Select “Adjust Time Delay”
3. Choose from the range of 1 min - 30 mins with 1 minute
increments
4. Select “Send”; remote displays “Settings Received”
SENSOR CONTROLS
A 60-second start-up period occurs during initial installation and
after a power failure of 5 minutes or more. After applying power
to the sensor, wait at least 60 seconds for the sensor to begin
detecting occupancy and the load to turn ON. Regardless of light
level the load may turn ON during the start-up period, depending
on the state of the relay when power was off.
• If the sensor detects occupancy during the start-up, when the
load turns ON it stays ON as long as the sensor continues to
detect motion, plus the Time Delay.
• If no occupancy is detected during the 60-second start-up, the
load may come on anyway during the start-up. If no occupancy is
detected by the time the start-up is complete, the relay opens and
the load turns OFF.
