We apologize this item has been discontinued.

The most advanced sensor available. Combines multi-technology with all-digital architecture. Eliminates false triggering. The result is a trouble-free, "install and forget" solution for lighting control.

	Simple, Fast Installation
	Self Adjusting (Adaptive)
	All-digital, Complete Reliability
	Ceiling Mount

General Operation

Occupancy sensors have two tasks: keeping the lights on while the room is occupied and, conversely keeping the lights off when unoccupied. Ultrasonic (doppler shift) motion detection gives maximum sensitivity yet can be vulnerable to false triggering from air conditioning currents, corridor activity and movement of inanimate objects. Infrared motion detection gives immunity to false triggering, but lacks sensitivity at greater distances.

Composite Multi-Tech Sensing:

Using infrared sensing (high error immunity) with ultrasonic (high sensitivity) provides good performance. Conventional multi-tech sensors use a simple formula for operation: BOTH for ON, EITHER for KEEP ON. This method requires that both sensors receive fixed-strength signals for ON or a single fixed-level signal for KEEP ON. The ceiling mount sensor uses a more sophisticated method called a composite signal where the signal strengths are added together to form a composite sum. The advantage of this method is that a week IR signal plus a strong US signal will turn the lights on because the sum is enough. The installer need not worry that the signal level be balanced for reliable lights on.

The Ceiling Mount constantly analyzes and adapts to changing conditions:

Period	Action	Time
Installation	60 min.	Timer automatically resets from Test (8 sec.) to 8 minutes.
Learning	Four weeks	1. Response to Error Conditions: (false-ons, false-offs) 2. Air current adaptation 3. Timer optimization Adjustments Made: Ultrasonic sensitivity Infrared sensitivity Timer Air current threshold
Post Learning- Occupancy Periods (Circadian)	After four weeks	1. 24 hour occupancy periods learned (circadian) 2. Weekly occupancy periods learned Adjustments Made: a. Generally occupied periods: Threshold=High Sensitivity mode b. Generally unoccupied periods: Threshold=Miser mode

Product Specifications:

Features:

	Two Operating Modes: Once the sensor has adapted to current room conditions, a threshold is set to determine which mode the sensor will reside in for that period. Once in Circadian Learning, the change between Miser and High Sensitivity modes is automatic.
	Self-adjusting Settings: Callbacks for adjustment are eliminated. Ultrasonic and infrared sensitivity, timer, and air current compensation are continuously analyzed.
	Non-Volatile Memory: Learned and adjusted settings saved in protected memory. Power outages will not cause status loss.
	Small Size: The spherical-section shape makes the installation almost invisible.
	Accurate, Consistent Switching: Occupant complaints are eliminated; lights are on when room is occupied, off when empty. Annoying false-offs are minimized and lights on at night is eliminated.
	Visual Status Reporting: By waving 5 times at the sensor, the status is visually reported through a coded light sequence.
	Fast, Simple Installation: A single mounting post and three color-coded wires make installation easy.

Automatic Timer & Automatic Sensitivity

The automatic timer and automatic sensitivity features of the ceiling mount work independently to prevent "false-offs" and "false-ons." When the unit detects motion immediately after it turns the lights out, a "false-off" is detected, timer and sensitivity are increased. If the sensor turns the lights on, but detects no immediate follow-up motion, "false-on" is detected, timer and sensitivity are decreased.

To speed installation and insure reliable operation, each sensor has an LED status lamp which flashes in red or green. Short Red flash = infrared motion detected. Short green flash = ultrasonic motion detected. A user may wave at the sensor five times rapidly (within five seconds) and the sensor will immediately flash its status and timer setting.

The following information is transmitted by the Green LED:
Timer setting: 0 - 90.
Ultrasonic sensitivity: 0 - 64.
Infrared sensitivity: 0 -64.
