Standard Range 360° Sensor - Ceiling Mount, Low Voltage, Dual Technology (PDT), RR7 Relay Compatible


The CM-PDT-RR7 Series Passive Dual Technology sensor is designed to interface directly with the G.E. RR-7 Relay and is ideal for open area office lighting control. This small, yet powerful sensor provides line of sight PIR detection of small motion in a circular pattern and combines overlapping Microphonicsâ„¢ coverage for detection of occupants working in their cubical space. By installing multiple CM-PDT-RR7s on 30 foot centers, large zones are created (typically one per circuit of lighting). The lighting is then controlled in blocks similar to manual switching, only no one will ever have to remember to turn off the lights! Restrooms with stalls, large storage areas with shelving, and libraries with study carrels are also easily and cost effectively controlled by the CM-PDT-RR7 sensor.

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.
