Greetings from Colombia
I had Homecontrols design my alarm system and bought all the devices from them.
They spec'ed a 4-wire connection to the glass break sensor, which we duly installed.
Come to find out, the sensor has a pwr/gnd, N-NC, Tamper and Reset pairs. Obviously this should have been wired with more than 4 wires...
Now, I'm looking for a way around this:
One pair goes to pwr/gnd
The tamper contacts lead to a micro-switch (NC, when cover installed). I was thinking of connecting one contact to GND and pulling the other to PWR with a resistor and using one of the remaining wires to connect to an ELK input. If it gets tampered with, and the contact opens, the ELK senses the input going up to PWR.
Will this work?
Likewise, on the actual glass break sensor, I would connect C to GND. As before, NC gets pulled to PWR. When triggered, NC pulls high and the remaining wires triggers the ELK...
Will this work?
Any additional hints (how to program the ELK input, what resistor to use, use SAUX to reset? etc) are, as always, highly appreciated!
Thanks...
