1 -The Steinel GLA-IR-QUATTRO-HD-COM1-24 is a ceiling-mounted occupancy sensor. The GLA-IR-QUATTRO-HD-COM1-24 can be used in standalone applications when paired with a GLPP, GLPAC, or GL-IPAC.
1 +The GLA-IR-QUATTRO-HD-COM1-24 is a ceiling-mounted occupancy sensor designed to provide coverage for areas up to 2,000 square feet. The sensor utilizes both passive infrared (PIR) and ultrasonic (US) motion sensors to allow reliable motion detection. The GLS-ODT-C-NS can be used in standalone applications when paired with a GLPP, GLPAC, or GL-IPAC.

3 3  === Note on GLA-IR-QUATTRO-HD-COM1-24 Power Draw ===
4 4  
5 -The listed power draw for GLA-IR-QUATTRO-HD-COM1-24 sensors is 32mA at 24VDC, however Chief Integrations' testing with shipped hardware shows the real-world power draw to be closer to 20mA. While GLPP modules are able to provide 150mA at 24VDC for sensors, applications with up to 4 have been shown to work.
5 +The listed power draw for GLA-IR-QUATTRO-HD-COM1-24 sensors is 32mA at 24VDC, however Chief Integrations' testing with shipped hardware shows the real-world power draw to be closer to 20mA. While GLPP modules are able to provide 150mA at 24VDC for sensors, this is sufficient for real-world applications involving 5 GLA-IR-QUATTRO-HD-COM1-24 occupancy sensors.

7 -Note: While calculations based on measured power draw would allow for up to 7 sensors on one GLPP, Chief Integrations cannot recommend exceeding manufacturer specifications.
7 +As such, Chief Integrations recommends adding a TR-100 or other external power supply if more than two sensors are required to be added to one GLPP.

9 9  === Detailed Analysis ===
10 10  
11 -The below measurements were taken with GLA-IR-QUATTRO-HD-COM1-24 attached to a GLPP-1DIMFLV2CN-PM with ~~1’ of wire using a Pokit portable oscilloscope in line to capture the current.  On startup, the sensor briefly draws 60mA before dropping to ~~20mA after 50ms.  20mA average consumption is fairly stable for the remainder of the sensor’s runtime.  Similar measurements were obtained with a Fluke 189 DMM so we know this Pokit capture is accurate.  Alternative measurements were taken with an HP 6632A DC power supply as the 24VDC power source and similar readings were produced and confirmed by the power supply’s internal meter.
11 +The below measurements were taken with GLA-IR-QUATTRO-HD-COM1-24 attached to a GLPP-1DIMFLV2CN-PM with ~~1’ of wire using a Pokit portable oscilloscope in line to capture the current.  The initial soft start (~~50ms) is followed by full operation which draws ~~20mA.  20mA average consumption is fairly stable for the remainder of the sensor’s runtime.  Similar measurements were obtained with a Fluke 189 DMM so we know this Pokit capture is accurate.  Alternative measurements were taken with an HP 6632A DC power supply as the 24VDC power source and similar readings were produced and confirmed by the power supply’s internal meter.

13 +Note, the Steinel IR Quattro HD sensors draw ~~60mA at startup but within 50ms drop down to 20mA steady state and remain there.  The Steinel sensors also have better coverage in our experience.
