Combo PIR and Glass Break

[Steve]

Has anyone used the DSC BV500GB ceiling mount PIR and glass break detector? Is there any reason to not use a ceiling mount over a corner mount in a residential environment? Is there a reason to not have a combined unit if you need both functions, or is it much better to have separate units? This seems like the most cost effective (both from purchasing and wiring in retrofit) way to go. Also, do you see any issue with this on a vaulted/cathedral/sloped ceiling?

I checked the link. This unit has a 40' diameter PIR coverage. Is it really going to respond to glass breakage in your entire room from that distance? Just a concern.

Those work pretty well. The only issue is if you need a pet immune sensor. The BV500 is not pet immune.

No, there is a sepate table for glass detection 10-25' depending on glass and sensitivity setting.
