About the Crestron GLA-DT-CM-COM1-24
Crestron offers STEINEL PROFESSIONAL sensors as part of its professional lighting and control range. The DT CM COM1-24 combines PIR with 40 kHz ultrasonic detection, and its light level feature turns the lights off when there is enough daylight. IQ Mode adjusts the ON time delay automatically by learning how each room is used.
It is a low-voltage sensor, powered at 18-24 VDC/VAC, for use with a power pack or a building automation system. Manual ON (MAN) and automatic (AUTO) modes are available, with a momentary or maintained switch input and a choice of ON only or ON and OFF manual switching. The COM-Link feature lets multiple sensors link together over the communication link.
Crestron lists typical applications as classrooms, conference rooms, computer rooms, storage rooms, open offices with cubicles, general open areas, washrooms, stairwells, and executive and private offices. Service and user wireless remotes are available. When replacing a detector, order the same part number so the supply voltage and features match.

Questions about the Crestron GLA-DT-CM-COM1-24
What is the Crestron GLA-DT-CM-COM1-24?
It is the STEINEL DT CM COM1-24, a dual technology presence detector offered by Crestron. It uses passive infrared and 40 kHz ultrasonic sensing to detect people in a space, and lighting is controlled according to both presence and the ambient light level.
How is the GLA-DT-CM-COM1-24 powered?
It is a low-voltage sensor that runs on 18-24 VDC/VAC. Crestron lists it for use with a power pack or a building automation system, so check which of these your lighting system uses when planning a new detector or replacing an old one.
What does dual technology mean on this detector?
The detector combines passive infrared (PIR) with 40 kHz ultrasonic sensing, which together give line of sight and volumetric presence detection. Logic options for the initial ON and maintained occupancy states give designers a choice in how lighting and building automation are controlled.
Does the detector respond to daylight?
Yes. Its light level feature turns the lights off when sufficient daylight is present, and lighting loads are controlled in relation to both presence detection and ambient light levels. IQ Mode also adjusts the ON time delay by learning individual room occupancy.
Can several GLA-DT-CM-COM1-24 sensors work together?
Yes. The COM-Link feature lets multiple sensors link together over the communication link for peer to peer operation. Service and user wireless remotes are also available, and the switch input can be momentary or maintained.
How much is the Crestron GLA-DT-CM-COM1-24?
Crestron asks its dealers to give the price of the GLA-DT-CM-COM1-24 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 GLA-DT-CM-COM1-24?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the GLA-DT-CM-COM1-24 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 GLA-DT-CM-COM1-24 come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the GLA-DT-CM-COM1-24 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 GLA-DT-CM-COM1-24 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 GLA-DT-CM-COM1-24 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.
