Overview
The Airflow Tolerant Circuitry™ sensor is designed to provide consistent
performance in all areas where strong air motion might cause false activation.
Airflow Tolerant Circuitry filters out the portion of the frequency spectrum related
to air movement to minimize false activations while it responds to object motion.
Ultrasonic sensors are ideal in spaces where you need increased sensitivity to
minor motion (like a hand waving) in larger spaces (>500 sq. ft.).
Operation
The sensor produces a low intensity, inaudible sound. It detects changes in the
acoustic waves caused by motion, such as reaching for a telephone, turning the
pages of a book, walking into a room, turning in a swivel chair, etc. The sensor
does not respond to audible sound. When the sensor detects motion, the relay
connected to the sensor is closed and the lights are turned ON. If no motion
occurs within a pre-set period of time, the lights are turned OFF. To ensure
continuous light when people are present, the timing can be set from 15 seconds
(for installer testing) to 30 minutes.
Application
conference rooms
classrooms
locker rooms
stock rooms
Other spaces which
have increased airflow
due to higher occupant
levels.

Mounting
SENSOR: Pass wires through the threaded mounting post and interlock to the backplate. The Sensor mounts to normal ceiling tile through a single
3/4” hole. When mounted, the Sensor’s slotted grills must point along the path where motion is to be detected. An Adapter Plate (ACMP) is available
to allow mounting to a standard fixture ring and junction box. The threaded mounting post may be cut down if it is too long to fit into the junction box.
CAUTION: Finger-tighten the nut to avoid stripping the mounting post.
SWITCHPACK: Designed to be mounted externally to any junction box. When mounted, the line connections are inside the box and the Class 2
wiring exits via the rear of the Switchpack housing. In areas where Class 2 wiring is not permitted, the Switchpack can be mounted internally to any
standard electrical box.
