DESCRIPTION AND OPERATION
The FS‑305 occupancy sensor turns lighting ON and OFF based on occupancy and ambient light levels. The light level feature can be
used to keep lights from turning ON if the ambient light level is sufficient. This slim, low‑profile sensor is designed for installation inside
the bottom of a light fixture body. The PIR lens connects to the FS‑305 through a 13/16” diameter hole in the bottom of the fixture.
The sensors use passive infrared (PIR) sensing technology that reacts to changes in infrared energy (moving body heat) within the
coverage area. Once the space is vacant and the time delay elapses (adjustable from 30 seconds to 30 minutes), lights will turn OFF.
Sensors must directly “see” motion of an occupant to detect them, so careful consideration must be given to sensor placement. Avoid
placing the sensor where shelving or other obstructions may block the sensor’s line of sight.
The FS‑305 operates between 12‑30VDC with Watt Stopper class 2 power packs. It is designed for installation in a light fixture.

INSTALLATION AND WIRING
CAUTION
TURN THE POWER OFF AT THE CIRCUIT BREAKER
BEFORE INSTALLING THE SENSOR.
1. Install the FS‑PP power pack as described in the instructions provided with the unit.
2. Determine an appropriate mounting location inside the light fixture for the FS‑305. Allow a minimum distance of 1.3” (33mm) from
the center of the sensor collar to the edge of the fixture.
3. Use a 13/16” (30mm) bit to drill a hole through the sheet metal in the bottom of the fixture.
4. From the inside of the fixture, insert the FS‑305 lens pipe through the hole in the bottom of the fixture. Install the sensor face
down, parallel to the mounting surface. Hand tighten the tightening ring securely against the outside of the fixture, followed by the
lens.
5. Connect control, load and supply wires as shown in Figure 2.
6. Restore power from the circuit breaker

Density and range of the coverage pattern is determined by the type of lens and mounting height. See the FS‑LxW Lens Module
Coverage Guide for a description of the available coverage patterns.
COVERAGE PATTERN
SENSOR ADJUSTMENT
The Light Level and Time Delay adjustment trimpots are located under the lens assembly.
The trimpots are accessed easily after the sensor is mounted in the fixture. Gently unscrew
the lens assembly. Do not remove the thumbscrew collar; it holds the sensor in place on the
fixture. Identify each trimpot.
Set the light level when the controlled light would normally be turned OFF due to the
presence of sufficient daylight or other electric light. [If this feature is not needed, leave the
light level at maximum (fully clockwise)].*
* At the maximum setting, the light level entering the photosensor must exceed 120fc,
which only happens in rare applications or when the lens is removed.
Test Occupancy Sensor
1. Set Light Level to maximum (fully clockwise, factory setting) and Time Delay to
minimum (fully counterclockwise). Put the lens assembly back onto the sensor.
2. Move out of the sensor’s view. Lights turn OFF after 30 seconds.
3. Move into the controlled area. The red LED in the sensor lens should illuminate and
the lights turn ON.
Test and Adjust Light Level Sensor and Time Delay
1. Remove the lens assembly and adjust the light level and the time delay to minimum. Put the lens assembly back onto the sensor.
Leave the controlled area and let the sensor time out so lights are OFF.
2. Enter the controlled area and lights should remain OFF.
3. Make sure your body does not cast a shadow on the sensor. Turn the light level trimpot
clockwise in small increments. After each adjustment, put the lens back on the sensor then
move about the controlled area. Wait 5‑10 seconds to see if the lights turn ON.
4. Continue this procedure until the lights turn ON. At this setting the lights will not turn ON with
occupancy if the light level is above the current level.
5. Set the time delay to the desired setting. The time delay can be set from 30 seconds (fully
counterclockwise) to 30 minutes (fully clockwise).
LIGHT LEVEL FEATURE
The Light Level feature holds lights OFF when the space is occupied and adequate ambient light exists. If the light level is low and the
sensor detects occupancy, lights turn ON. If the light level rises above the set level during occupancy, lights stay ON.
In all cases, the sensor does not turn the lights OFF until the time delay expires.
The factory setting is for maximum, meaning that even bright ambient light will not cause the sensor to hold the lights OFF if it detects
occupancy in the controlled area. *
WARNING
DO NOT OVERTURN TRIMPOT WHEN ADJUSTING THE SENSOR.
DO NOT TOUCH THE SQUARE INFRARED DETECTOR UNDER THE LENS ASSEMBLY.

TROUBLESHOOTING
Lights will not turn ON:
• LED does not flash
▸ Check all wire connections.
• LED does flash:
▸ Check all wire connections.
▸ Check light level setting. Cover the sensor lens to simulate darkness in the room. If the lights come ON, the light level needs
to be adjusted. If set for minimum, more than 10fc of ambient light will cause the lights to be held OFF. See Sensor Adjustment
section for instructions.
• If lights still do not turn ON, call 800.879.8585.
Lights will not turn OFF:
The time delay can be set from a minimum of 30 seconds (fully counter‑clockwise) to a maximum of 30 minutes (fully clockwise). Ensure
that the time delay is set to the desired delay and that there is no movement within the sensor’s view for that time period.
• To quickly test the unit for proper operation, turn the time delay to minimum and move out of the sensor’s view. Lights should turn
OFF after 30 seconds.
• If lights still do not turn OFF, call 800.879.8585 for technical support.
Operation during Power-Up
During the sensor warm‑up period, which can last up to a minute after initial power‑up (or after a lengthy power outage), the load will
remain ON until the selected time delay expires.
