Crestron GLS-ODT-C-CN Dual-Technology Occupancy Sensor with Cresnet

Crestron part number GLS-ODT-C-CN

The Crestron GLS-ODT-C-CN is a low-profile ceiling occupancy sensor that combines ultrasonic and passive infrared detection to cover large areas of up to 2,000 sq ft. Its Cresnet connection links it directly to a Crestron control system for integrated control of lighting, climate and other devices in the room.

About the Crestron GLS-ODT-C-CN

Ultrasonic sensing picks up small movements across a large area, while passive infrared gives strong immunity to false triggers, so together they deliver consistent, dependable occupancy detection. The sensor has a 360° coverage pattern, a discreet low-profile look and fully digital circuitry. A built-in photosensor provides ambient light recognition, and there is also an input for an external photosensor.

When the sensor detects only momentary occupancy, Walk-Through mode turns the lights off after 90 seconds. In a room programmed for vacancy only, a 15 second grace period follows the lights going off, and a wave of the hand brings them back on. With ambient light recognition enabled, the sensor can stop the lights switching on when ambient light is above a set threshold.

Cresnet gives the Crestron control system a direct connection to the sensor for integrated control of lighting, climate control and other devices in the room. Crestron's GLS-REMOTE-ODT/OIR IR remote, sold separately, is designed for this sensor and handles full setup and a variety of sensor parameters from beneath it, without a ladder.

Questions about the Crestron GLS-ODT-C-CN

What is the Crestron GLS-ODT-C-CN?

It is a low-profile, ceiling-mounted occupancy sensor for large areas of up to 2,000 sq ft. It combines ultrasonic and passive infrared detection and connects to a Crestron control system over Cresnet, so occupancy can drive lighting, climate control and other devices in the room.

Why does the GLS-ODT-C-CN use two sensing technologies?

Ultrasonic detection is very sensitive to small movements over a large area, while passive infrared sensing gives strong immunity to false triggers. Using both together gives consistent, dependable occupancy sensing across the sensor's 360° coverage pattern.

What is the difference between the GLS-ODT-C-CN and GLS-ODT-C-NS?

Both are dual-technology ceiling sensors covering up to 2,000 sq ft. The GLS-ODT-C-CN communicates with a Crestron control system over Cresnet and adds built-in ambient light recognition and an external photosensor input. The GLS-ODT-C-NS is made for standalone lighting systems, connecting to a Versiport or digital input, with a GLS-SIM (sold separately) as its Crestron interface.

Can the sensor stop lights coming on in daylight?

Yes. The built-in photosensor detects the ambient light in the room. When this feature is enabled, the sensor can override its occupancy signal so the lights do not switch on if the ambient light is above a set threshold, which keeps them off when there is enough daylight.

Which remote works with the GLS-ODT-C-CN?

Crestron's GLS-REMOTE-ODT/OIR is an IR remote designed for this sensor, and it is sold separately. It carries out full setup functions and adjusts a variety of sensor parameters from beneath the sensor, which removes the need for a ladder. It runs on two AAA batteries, which are included.

How much is the Crestron GLS-ODT-C-CN?

Crestron asks its dealers to give the price of the GLS-ODT-C-CN directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.

Can 1Install supply, install and programme the GLS-ODT-C-CN?

Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the GLS-ODT-C-CN on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.

Does the GLS-ODT-C-CN come with a warranty?

Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the GLS-ODT-C-CN develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.

Is the GLS-ODT-C-CN in stock?

We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.

Can I buy the GLS-ODT-C-CN without installation?

Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
