Crestron GLS-OIR-C-NS Passive Infrared Ceiling Occupancy Sensor

Crestron part number GLS-OIR-C-NS

The Crestron GLS-OIR-C-NS is a low-profile ceiling occupancy sensor that uses passive infrared (PIR) detection to cover areas of up to 2,000 sq ft. It connects directly to and is controlled by standalone lighting systems, and the GLS-SIM module, sold separately, provides an interface to a Crestron control system.

About the Crestron GLS-OIR-C-NS

A specialised, highly sensitive lens divides the field of view into zones. When a person moves into or out of a zone, the sensor detects the motion and switches the lights on, and they stay on while motion continues. PIR gives excellent detection with strong immunity to false triggering across a 360° pattern, and the sensor connects to a Versiport or digital input port.

When only momentary occupancy is detected, Walk-Through mode turns the lights off after 90 seconds. On a drywall or drop-tile ceiling the sensor has a discreet, nearly hidden appearance. Hardware is included for a standard 4-inch octagon box, and a cutout template is provided for mounting in a hole in the ceiling.

For a Crestron system, the GLS-SIM Sensor Integration Module provides the interface to the control system; it gives compatible sensors a Cresnet connection and supplies 24 VDC to power one or more sensors. The GLS-REMOTE-ODT/OIR IR remote, also sold separately, is designed for this sensor and handles full setup and a variety of sensor parameters from beneath it.

Questions about the Crestron GLS-OIR-C-NS

What is the Crestron GLS-OIR-C-NS?

It is a low-profile, ceiling-mounted passive infrared occupancy sensor for standalone lighting systems. It covers up to 2,000 sq ft with a 360° pattern, gives excellent motion detection with strong immunity to false triggering, and connects to a Versiport or digital input port.

Can the GLS-OIR-C-NS work with a Crestron control system?

Yes. The GLS-SIM Sensor Integration Module, sold separately, provides the interface between this sensor and a Crestron control system. The GLS-SIM connects sensors to a Cresnet network and allows fully programmable operation as part of a Crestron system.

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

Both are PIR ceiling sensors for areas up to 2,000 sq ft. The GLS-OIR-C-NS is made for standalone lighting systems and connects to a Versiport or digital input, with a GLS-SIM for Crestron integration. The GLS-OIR-C-CN connects directly over Cresnet and adds built-in ambient light recognition and an external photosensor input.

How is the sensor mounted?

It fits a drywall or drop-tile ceiling, where it has a discreet, nearly hidden appearance. Hardware is included for mounting in a standard 4-inch octagon box, and a cutout template is provided for mounting it in a hole in the ceiling instead.

Which remote works with the GLS-OIR-C-NS?

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-OIR-C-NS?

Crestron asks its dealers to give the price of the GLS-OIR-C-NS 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-OIR-C-NS?

Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the GLS-OIR-C-NS 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-OIR-C-NS come with a warranty?

Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the GLS-OIR-C-NS 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-OIR-C-NS 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-OIR-C-NS 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.
