Relay Compatible Sensor Heads- Microphonic
The Sensor Switch Line of G.E. RR-7 Relay Ceiling Mount Sensors was specifically designed to provide an economical approach to controlling areas in which a wall switch replacement sensor is not applicable. The Ceiling Mount Sensors may be available in single technology (PIR) or dual technology (PDT). Each sensor provides a coverage of 360 degrees. The Ceiling Mount Sensor may also be recessed (for aesthetics) in the ceiling. (Use #CM-RPX accessory recess plate.)
SENSOR OPERATIONS:
The Ceiling Mount Sensors control lighting through G.E. RR-7 Relays. The sensors turn on the lights when an occupant enters the room. The PDT products use PIR (Passive Infrared) and Microphonics in combination with a Fresnel Lens. The PIR portion of the sensor detects an occupant entering the room and turns on the lights. Once on, the Microphonic portion is engaged to detect occupant "noise". As an occupant moves within the field-of-view, the sensor detects a change in motion and temperature. Every time an occupant moves or noise is made, the time delay circuit is reset. Each sensor provides for an adjustable time delay from 30 seconds to 20 minutes. After a period of time the sensor will automatically time out, turning the lights off. A 10 second grace period is provided to voice reactiviate the system if needed.
SENSOR FEATURES:
The time delay is adjustable from 30 seconds to 20 minutes. It can be adjusted manually with a small precision screwdriver (enclosed). The Ceiling Mount Sensor features a single pole, double throw isolated relay that can be interfaced with HVAC, EMS monitoring systems, and DDC systems. It has normally open and normally closed outputs and is rated for 1 Amp at 40 VDC. The Ceiling Mount Sensor can also be equipped with Dual Technology Micophonics, thus giving a double coverage to an area with obstructions.
MULTI-SENSOR APPLICATIONS
When multiple sensors are required to control one zone, the GE RR7 Sensor accepts signals from other remote low voltage sensors. A 24 VDC "High" signal from the remote sensor indicates an "On" condition. Standard Sensor Switch low voltage sensors (i.e., CM-9, WV-1 6, CM-PDT, WV-PDT, or HW-13) may be used as remotes. Or, signals from other control devices may be used to override the system to On.
INSTALLATION CONSIDERATIONS:
The Ceiling Mount Sensor was designed to be mounted in an indoor, air-conditioned, commercial environment. Recommended mounting height is 8 to 12 feet for maximum performance. The PDT line of sensors, unlike any other occupancy sensor, self-adjusts to itÕs environment. The Automatic Gain Control (AGC) feature allows the sensor to tune out constant background noise. However, changing noise signals like talking, shuffling of papers, and general human activities are readily detected. Avoid locating the sensor near HVAC air diffusers because the noise generated from the air flow will decrease the sensitivity of the microphonic sensor. Care should also be taken that the PIR collector beams do not view outside the controlled area.
