Crestron ZUMLINK-US-QUATTRO-DLS-RLY Ultrasonic Sensor with Relay

It is a STEINEL ultrasonic presence detector with daylight sensing, HVAC control and Zūm Link communication for Zūm wired lighting control. It mounts in the ceiling, detects presence with omnidirectional ultrasonic sensing across 360°, measures daylight with a closed loop sensor, and has an output relay for a relay-input capable device.

It allows the detector to control a relay-input capable device, and Crestron's title for this model lists HVAC control. It offers normally open, normally closed and common connections, and Crestron rates the control output at 1A at 30VAC/VDC. The ZUMLINK-US-QUATTRO-DLS is the same ultrasonic detector without the relay.

It covers 360° using omnidirectional ultrasonic sensing at 40 kHz, up to a maximum zone of 40 x 50 ft (2,000 sq ft), or 12 x 15 m (180 sq m), for major motion as described by NEMA WD7. The daylight sensor has a light level setting of 10 to 1000 lux.

It draws its power from the Zūm Link bus, up to 28 mA. For daisy-chaining it has two orange RJ-45 ports, which take CBL-CAT5E-ZUMLINK-P CAT5e cable (sold separately) to load controllers, keypads and other Zūm wired devices in the room, with up to 750mA of pass-through current.

Crestron lists three ceiling options: directly in the ceiling, in a 4 in. square or round junction box, or on a 3 in. mud ring, with no box or ring included. The plastic detector measures 121 mm by 121 mm, is 68 mm deep, carries an IP20 rating and operates from 0° to 40°C.
