Infrared occupancy sensor

The Gentec RVS is a ceiling mount solar powered, passive infrared, wireless vacancy sensor. Optimized for spaces with ceiling heights of 8 to 10 feet, the RVS provides automatic OFF control, meeting today’s strictest energy codes. The Resonate Vacancy Sensor combines a sleek, non-intrusive design with advanced power management circuitry to minimize solar harvesting requirements.

The RVS will operate as a self-powered vacancy sensor in low light conditions. The RCS is identical to the RVS with the addition of a battery to provide power for support of auto-on occupancy sensor applications. The Resonate Vacancy/Occupacy Sensors incorporate Gentec’s latest diagnostic and configuration features to ensure reliable communications and solar harvesting capability. The
RVS/RCS supports range confirmation* technology whereby simple button press and hold sequences result in LED indication of signal strength. Solar energy harvesting level indication under existing light levels is also provided on demand through LED indication. An efficient power supply design takes advantage of every foot-candle so the sensor will operate as a vacancy sensor with just the energy from artificial lights.

Gentec has incorporated a diagnostic walk-test feature that verifies motion detection plus sensitivity adjustment to prevent false motion triggers.

The sensor transmits occupancy or vacancy states detected via the on-board motion detector. In vacancy sensor applications with a manual switch, the RVS sensor automatically triggers lights-off after the room is vacant and an egress timer expires. For occupancy sensor applications with the battery installed, the RCS transmits immediately upon a new
occupied event allowing for full lights-on and lights-off automation.

The RVS/RCS Sensors are a key component in Gentec’s Smart Space solutions, delivering energy savings to classrooms, open office spaces and corridors.

*Note: Range Confirmation requires an “F series” Gentec controller (“F” series is exclusive to 902 MHz at this time).
