The DSC BV-501GB is the version of the ceiling-mounted Bravo 5 sensor that includes both a PIR motion detector and a glass break sensor. The device is Form A (normally closed wiring) for the motion and Form C (normally open or normally closed wiring) for the glass break. Buy the BV-501GB here.

The DSC BV-501GB Bravo 5 Ceiling-Mount PIR Motion & Glass Break Detector can accurately detect motion and the sound of breaking glass. This is one of the few sensors that can achieve this type of multipurpose function. With its 360 coverage, it will detect any problems that occur below.

The motion detector on the BV-501GB uses passive infrared (PIR) technology to sense motion. This is done by looking for changes in infrared energy caused by movement. The quad element PIR sensor uses multi-level signal processing (MLSP). This allows the sensor to recognize the difference in motion between human intruders and other possible sources of motion. And with its temperature compensation feature, the sensor will still function properly when the temperature is close to that of the body. Both high sensitivity and low sensitivity settings are available.

The BV-501GB glass break sensor consists of a micro-controller that features digital signal processing technology. The sensor uses special Dynamic Signal Processing to successfully detect the sound of plate, laminated, wired or tempered glass being broken. Additionally, the sensor will ignore any "bell" or "ringing" sounds that have a similar sound frequency to breaking glass. This feature is particularly useful, as it prevents false alarms from occurring. The device's "white noise" rejection mechanism prevents the device from being activated by background noise.

There are a few things to consider when choosing a mounting location for the BV-501GB. It should be mounted on the ceiling and have a direct line of sight to any glass that is being monitored. For the motion sensor to work properly, the sensor should not be facing towards any reflective surfaces, heavy air flow, moisture, sunlight or obstructions. The sensor should also not be placed directly by any noise-making devices, as they may inadvertently cause false alarms if they are making noise right into the device's microphone. Remember to follow these guidelines when mounting the sensor.

Please note that this version of the Bravo 5 uses Form A wiring (normally closed only) for the motion and Form C wiring (normally open or normally closed) for the glass break. The device also includes a tamper switch. DSC makes another version of this exact same sensor that does not include the tamper switch (BV-500GB). Another sensor is the BV-502GB, which also features a tamper switch, but is Form C for both the motion sensor and the glass break. DSC also produces these same three sensors with only the PIR motion and without the glass break function (BV-500, BV-501 and BV-502).
