Sensors with Passive Dual Technology (PDT) first "See" motion using Passive Infrared (PIR) and then engage Microphonics™ to "Hear" sounds that indicate continued occupancy. This patented technology uses Automatic Gain Control (AGC) to dynamically self adapt a sensor to its environment by filtering out constant background noise and detecting only noises typical of human activity. An internal timer, factory set at 10 minutes, keeps the lights "On" during brief periods of no activity. This timer is selectable push-button programmable from 30 seconds to 20 minutes, and is reset every time occupancy is re-detected. System power is provided by a Class II 24 VAC transformer.
The G.E. RR-7 relay interfaces to the sensor via a 3-wire parallel connection to the local (SPDT “Momentary” type) switch. No wires from the sensor to the transformer are required; an advantage considering most transformers are typically located in a centralized panel and not easily accessible. Upon occupancy, the sensor pulses the wire to the "On" switch terminal causing the RR-7 relay to turn on the lights. Once the sensor time delay expires, it pulses the wire to the "Off" switch terminal causing the RR-7 relay to turn off the lights. The local switch can also pulse on and off the relay. For example, a room is occupied with the lights on and the occupant leaves and pulses the switch off. The sensor later times out and sends a redundant "Off" pulse. Then, when an occupant enters the sensor pulses lights on. However, if the occupant re-enters prior to the sensor timing out, the lights would remain off until the manual switch was pulsed on.
