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

from vertical. It is particularly well suited for use in stairwell applications, as well as in other wall mount applications.

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.

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.

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.
