Are there any dealer spec sheets that show sensor compatibility with the different legacy radio versions of the IQ 2+ panel?
Yes, we have a list here:
If starting from scratch I would recommend the 319.5 version. This provides access to two encrypted sensor lines which can be used simultaneously: PowerG and S-Line.
Also is there any suggested reading to help me best evaluate idea quantity and placement for glass breaks and motion sensors?
Placement for these devices will be based on the model’s specifications. Follow the range and mounting guidelines set by the manufacturer to ensure best performance. Check out the manuals for the models you are looking at or if you have any questions we can help recommend some.
Mounting many motion detectors too high or low can cause excessive false alarms or limit range significantly.
There are definitely some general tips to best avoid false alarms with these devices. We have some general troubleshooting help threads like this one for motion detectors.
Glassbreak detectors are not directional usually but still require line of sight, which some people don’t expect when installing, as intervening walls or some other material can dampen the sound it is listening for.
