DSC BV-502GB - Bravo® 5, 360 Degrees Ceiling-Mount PIR Motion & Glassbreak Detector w/ Tamper Reviews
Submitted on 04/22/2020 Alarm Grid
The DSC BV-502GB is a hardwired glass break detector and ceiling-mount PIR motion sensor with 360-degrees of coverage. In order to get full use out of this sensor, you must wire it to two (2) separate hardwired zones on your system. One zone is for glass break detection, and the other is for motion detection. The terminals are appropriately labeled so that you can easily tell which is which. This is an example of a wired combination sensor done right, and while having two completely different functions in one is a bit unorthodox, it still works very well when set up correctly. For that reason, we give the DSC BV-502GB a 5 Star rating.
There are many things we like about the DSC BV-502GB. For one, it combines two sensors into one, which can save you from having to make an additional purchase. The two functions are wired individually and set up with different zones. If you don't want to utilize one of the functions, then you can just leave the corresponding terminal unwired, and you won't need to program for that function at the panel. In other words, you can use the device as a standalone glass break, a standalone motion, or both a glass break and motion. The device is Form C, allowing for both NC and NO wiring. The PIR sensor features multi-level signal processing, and it is quad-element. This helps ensure that the sensor responds reliably to motion, while also not prone to false alarms.
There are a few downsides regarding the DSC BV-502GB. If you really intend on using it as both a ceiling-mount motion AND as a glass break detector, you will need to choose a location very carefully. It must be able to detect the sound of glass breaking and detect movement that occurs below. Make sure to test both functions accordingly. And you will still need two (2) zones on the panel for full functionality. Make sure you have enough zones available. Also consider obstacles that can prevent the device from working properly. It should have a direct line of sight to the windows and the area below. Overall, this is a good sensor, but you need to make some key considerations when using it. We give it 5 Stars, at fulfills its role very nicely when used properly.
Good: Two Sensors In One, Wire/Program Glass Break & Motion Individually, Form C, Multi-Level Signal Processing, Quad-Element PIR, Not Prone To False Alarms When Used Correctly
Bad: Location Must Be Selected Very Carefully If Both Motion & Glass Break Are Being Used, Requires Two (2) Zones For Full Functionality, Obstacles Can Interfere w/ Device
Bottom Line: 5 Stars
