Frequently Asked Questions - GLS-OIR-C-NS Crestron
How do I adjust the time delay on the GLS-OIR-C-NS?
The time delay is adjusted via a potentiometer on the sensor. Turn clockwise to increase delay (up to 30 minutes) and counterclockwise to decrease (minimum 30 seconds). Refer to the manual for exact location.
What is the detection range of the GLS-OIR-C-NS?
The detection range is up to 30 feet (9.1 m) in a 360-degree pattern at a mounting height of 8–12 feet. Coverage area is typically 1500 sq ft.
Can I use the GLS-OIR-C-NS outdoors?
No, this sensor is rated for indoor use only. It should be mounted in a controlled environment with temperature between 32°F and 104°F.
How do I wire the GLS-OIR-C-NS?
The sensor uses a 4-pin terminal block: connect 24 VDC power (V+ and V-), and the relay output (COM, NO, NC). Ensure power is off during installation.
What does the photocell do?
The built-in photocell measures ambient light level. You can set it so the sensor only activates when light is below a threshold, saving energy in well-lit spaces.
Why is my GLS-OIR-C-NS not detecting motion?
Check that the sensor is powered (24 VDC), the time delay is not set too short, and there are no obstructions in the detection zone. Also verify the photocell setting if enabled.
Can I mount the GLS-OIR-C-NS on a wall?
Yes, it can be wall-mounted using the provided bracket. Ensure the sensor is at the recommended height (8–12 ft) and has clear view of the area.
What is the maximum load for the relay?
The relay is rated for 1 A at 30 VDC (resistive). Do not exceed this rating to avoid damage.
How do I clean the GLS-OIR-C-NS?
Wipe the lens and housing with a soft, dry cloth. Do not use any liquids or cleaning solvents as they may damage the sensor.
