GSM Alarm: connecting hardwired sensors to alarm panel

By default, the GSM alarm is using NC. That's circuit open will alarm.

Most wired sensors (door contacts, PIR motion detectors, gas leakage detector, smoke detector, etc) have two wires. Connecting one wire to i1, i2, or i3 of the alarm panel, and another one wire to the GROUND of alarm panel. That's all.

Alarm panel got 3 inputs, so you can define 3 zones. Of course, you can connect all your sensors in series or in parallel, just depends on which cabling will better fit your situation.
