DESCRIPTION AND OPERATION
The FSL-505 and FSL-505C occupancy sensors turn lighting on and off based on occupancy. The
sensors use ultrasonic sensing technology. Once the space is vacant and the time delay elapses
(adjustable from 5 to 30 minutes), lights will turn off.
The FSL-505 and FSL-505C operate at 24VDC. They are designed for
installation in a light fixture within 2 feet of an associated power supply. The
power supply for the sensors is a FS-PP power pack mounted inside a light
fixture. Each Wattstopper FS-PP power pack can supply power for one
FSL-505 or FSL-505C sensor.
The sensors are equipped with a 2' long cable fitted with a shielded male RJ45 plug. The FS-PP has a
corresponding female RJ45 receptacle. This cable carries power to the sensor and the 24VDC maintained
output to the power pack to signal that lights should be on. Optional cables and connectors are available for
alternate configurations.
Important, there is an initial warm-up period:
It may take up to a minute before the lights turn on due to a sensor warm-up period
required during initial power-up. This occurs during installation or after a lengthy
power failure only.

The FSL-505C is designed for use in hanging light fixtures where the cones face downward over the coverage area. This gives the
FSL-505C a large rectangular shaped coverage pattern (see the Coverage Pattern section).
The FSL-505 (no cones) is designed for use in wall-mounted lighting fixtures where the transducers face away from the wall at an angle
of approximately 20
o
from vertical. It is particularly well suited for use in stairwell applications, as well as in other wall mount applications.

INSTALLATION
1. Install the FS-PP as directed in the installation instructions provided with the power pack.
Review wiring diagrams below and on page 5, to determine appropriate load wiring to the FS-PP and Occupancy Mode Switch
setting for the FSL-505.
2. Determine an appropriate mounting location inside the light fixture.
3. See template for dimensions to determine cut-out and mounting hole locations in the fixture.
4. Install the sensor to the inside of the fixture using screws.
5. Plug the FSL-505 into the FS-PP.
6. Restore power from the circuit breaker.
WARNING: TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE WIRING.

COVERAGE PATTERN
The coverage pattern is determined by sensor model, mounting height and the angle of the sensor, relative to the coverage area floor.
The coverage shown represents full-step walking motion in a carpeted area, with no barriers or obstacles at a mounting height of 8 to 10
feet. Mounting above or below this range significantly affects coverage patterns.
Obstacles such as furniture or partitions, wall, ceiling and floor treatments can cause the coverage area to be less or more than the
sensing distances shown in the coverage pattern. This must be considered when planning the number of sensors and their placement.
Place sensors at least 4 feet away from air supply ducts.
For complete coverage in open areas, install multiple sensors to provide a 20% overlap with each adjacent sensor’s coverage area.

SENSOR ADJUSTMENT
Before making adjustments, install furniture, turn lighting circuits on, and set HVAC systems to the overridden/on position. VAV systems
should be set to their highest airflow. Set the Time Delay to the desired setting. See “Time Delay Switches” on the next page.
Factory Default Settings
S2-1 ON, S2-2 OFF, R18 WIPER @ 3.8 V, S3 OFF
To Test Occupancy Sensors
1. Set the Sensitivity adjustment to about mid-range.
2. Activate the Test Mode using the test mode button.
3. Move out of the controlled area - the lights will turn off in about 5 seconds from the last flash of the LED.* If the LED continues
to flash, the sensor is detecting some kind of movement. Change the sensitivity adjustment to a lower setting (a few degrees
counterclockwise) and repeat this step until the LED does not flash and the lights turn off.
4. * If Reverse-Occupancy is enabled (the lighting load is wired to a normally closed contact and the sensor’s Occupancy Mode
Switch is ON), operation of the load is also reversed during Test Mode. For example, at this stage of testing, the lights will turn ON
in about 5 seconds from the last flash of the LED. See the Occupancy Mode Switch section for more information.
4
5. Walk into the controlled area. If the lights don’t turn on, increase the sensitivity (a few degrees clockwise) and try again. Repeat
this procedure until the LED does not flash and the lights turn off. If the lights turn off while the room is occupied, it may be
necessary to increase the sensitivity.
6. Allow the test period to expire or push the test button again. The sensor will now be in its operating mode.

Adjustment Features
LED
The LED flashes every time the sensor detects motion. The LED is also used to indicate other sensor status such as test mode, lamp
burn-in, and override. When the LED flashes at a constant rate of one second on then one second off, the sensor is in the burn-in mode.
When the sensor is in Test Mode, the LED flashes to indicate occupancy detections. When the sensor is in Override Mode, the LED
glows steady.
TIME DELAY SWITCHES
The sensor will hold the lights ON as long as occupancy is detected. The time delay countdown starts when no
motion is detected. After no motion is detected for the length of the time delay, the sensor will turn the lights OFF.

TEST MODE BUTTON
This button is used to select the Operating Mode for the FSL-505.
• A momentary press invokes the Test Mode.
• Press and hold for 5 seconds to invoke the lamp Burn-In mode.
• Press and hold for 10 seconds to Override the sensor output.
The LED lights indicate how long the button is to be held. Initially the LED is cleared when the button is pressed. After 5 seconds it will
turn on, and after 10 seconds clear again.
Test Mode
The purpose of the test mode is to be able to quickly determine the coverage area of the sensor without waiting for a lengthy time delay.
Test Mode is a temporary state that provides a 5 minute test period. During the test period, the Time Delay is only 5 seconds. After 5
minutes, the sensor returns to the time delay set on the Time Delay switches. To exit from the Test Mode, push the button again or wait
for it to time out.
Override
To override sensor functions so that the load stays on, push and hold the button for 10 seconds. Depending on the setting of the
Occupancy Mode switch, the output could be overridden ON or OFF. The LED is ON in a steady state when the sensor is in the
Override Mode. When in override, the lights can be manually controlled with a light switch, if one is installed. To turn off the Override
Mode, momentarily push the button again.
Burn-in
Some lamp and ballast manufacturers recommend running lamps at full output for their first 72 hours of operation. The burn-in function
initiates a 72-hour burn-in period. To start the burn-in process, push and hold the button for 5 seconds. The lamps will stay on for 72
hours continuously, regardless of occupancy status. After 72 hours, the sensor returns to normal function. To indicate the sensor is in
burn-in mode, the LED flashes rapidly and continuously for the full 72 hours. To turn off the burn-in mode, momentarily push the button
again.
5
OCCUPANCY MODE SWITCH
When the sensor is used with a power pack incorporating a normally closed relay, the Occupancy Mode Switch can be set for Fail-ON
functionality, or reverse-occupancy operation. To use the normally closed relay on the FS-PP, wire the lighting load to the NC and COM
terminals as shown in Figure 11.
Fail-ON Functionality
To enable Fail-ON functionality, set the Occupancy Mode Switch to OFF and wire the load as shown in Figure 11. In this configuration
the sensor works normally, meaning that it turns ON the lights when there is occupancy, and turns OFF the lights when the Time Delay
expires. Should the sensor be disconnected or fail, the lights turn ON.
Reverse-Occupancy Functionality
If the switch is set to ON in the N/C wiring configuration, the operation will be reversed. The lights turn ON when there is no occupancy,
and turn OFF when there is occupancy. However, if the sensor is removed or fails, the lights will turn ON due to the kickback circuitry in
the FS-PP.
