Passive Infrared (PIR) motion detectors use a 3 or 4-wire connection for power, ground, tamper, and relay output to connect to alarm panels for detecting human movement in security zones.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | VCC | Supply voltage 9V-16V | PWR |
| 2 | GND | Ground | GND |
| 3 | NC | Normally closed relay output | I/O |
| 4 | COM | Relay common | I/O |
| 5 | TAMPER | Tamper circuit | I/O |
