Hi,
We've decided to add some glass break sensors to our indigo based system (I also have a GE Concord Alarm system which I could use... prefer Indigo because of flexability). I really know little about glass break sensors but I like that they can be left on 24/7 regardless of whether we're home or not. Here is where I'm at:
1) I know that Insteon does not make a glass break sensor, but I realize that I could use an IOLinc, a TriggerLinc, or some EZIO module to interface with a 3rd party glass break sensor.
2) I've seen a line of glass break sensors made by Honeywell which many people use with wired professionally installed systems. Honeywell glass break sensors have very good reviews.
3) I'm having a hard time finding electrical information on the Honeywell sensors.
4) In my uneducated mind, I would want a glass break sensor to work much like the Insteon Leak sensor... in other words, once it goes off, it "latches" and then you locate the sensor, presumeably discover the reason for the glass break alarm activation, then you reset the device. I would like a signal from the glass break sensor of some DC voltage, or even if the sensor has a relay closure which pulls the line to some predetermined voltage.
5) The honeywell sensors have 4 or more pins and are powered by 9 to 14 volts. A couple of pins for power and a couple of pins for signal... they also talk about a resistor terminator for end of line termination. I don't know yet if the sensors send out a "blip" or if they latch or if they send out who knows what? That information is still fuzzy for me.
I have a way to wire up these glass break sensors for most locations in my home; I was planing on using CAT5 for both power and signals.
Questions:
Are my assumptions about how glass break sensors work any good and how I would interface to them correct? Any advice on connecting such sensors?
Any recommendations for particular glass break sensors? (I'm not looking for wireless solutions)
TIA,
