Units with the dry-contact hardware option enabled are equipped with four dry-contact inputs that enable you to monitor and report the status of external devices.
The reporting of the current state of each dry-contact input is found in System ▶ Alarm ▶Dry-Contact.

| Pin | Signal |
|---|---|
| 1 | GND1 (ground) |
| 2 | DC1 (dry-contact 1 input) |
| 3 | GND3 (ground) |
| 4 | DC2 (dry-contact 2 input) |
| 5 | GND2 (ground) |
| 6 | DC3 (dry-contact 3 input) |
| 7 | GND4 (ground) |
