2GIG Sensor Types & Groups (GC2/GC3) — What Each Zone Does
Every sensor in a 2GIG system is assigned a sensor number (zone ID) and a sensor type (group). The number uniquely identifies the device in logs and at the panel, while the type tells the panel when and how to react—instantly, with entry/exit delays, 24-hours a day, silently, or audibly.

How Sensor Numbers & Types Work
- Sensor number (zone): The unique slot you program a wireless or wired sensor into. Used for display, event logs, and monitoring reports.
- Sensor type (group): Defines behavior—armed states (Stay/Away), delays, local sounder/bell output, reporting, and whether it’s always active.
- Entry/Exit delays: Entry delay starts on designated doors; you must disarm before it expires or an alarm occurs. Exit delay runs after arming.
- Always-active (24-hour): Triggers regardless of arming state (e.g., fire, CO, auxiliary, audible/silent panic).

2GIG Sensor Groups & Types
| Group | Sensor Type | Description & Typical Use |
|---|---|---|
| 0 | Unused | For empty zone slots. No panel action or reporting. |
| 1 | Exit/Entry 1 | Primary entry door. Triggers Entry Delay #1 when opened after arming. Acts instant if entry delay is disabled. Use for main doors. |
| 2 | Exit/Entry 2 | Same behavior as Group 1 but starts Entry Delay #2 (often longer), e.g., garage entries. |
| 3 | Perimeter | Doors/windows not used for entry after arming. Instant alarm in Stay or Away. |
| 4 | Interior Follower | Interior motion/doors. After Exit Delay, trips instant—unless an entry/exit sensor is opened first, in which case it follows the entry delay. Bypassed in Stay. |
| 5 | Day Zone | Like perimeter, but when disarmed a violation shows a trouble (and may report). Use for sensitive areas needing notification while disarmed. |
| 6 | 24-hour Silent Alarm | Always active. Sends a silent panic code to monitoring—no local sound/visuals for safety. |
| 7 | 24-hour Audible Alarm | Always active. Triggers local alarm and bell output. Typical: audible panic. |
| 8 | 24-hour Auxiliary Alarm | Always active. Triggers alarm and local sounder only (no bell output). No time-out; stops with a valid code. Common: flood/temperature. |
| 9 | 24-hour Fire † | Always active. Triggers fire sounder + bell. Typical: smoke detectors. Cannot be bypassed. |
| 10 | Interior with Delay | In Away, starts Entry Delay #1 when tripped. In Away-Instant, alarms instantly. Bypassed in Stay. |
| 14 | 24-hour Carbon Monoxide † | Always active. Triggers CO pulse sounder + bell. Typical: CO detectors. Cannot be bypassed. |
| 16 | 24-hour Fire with Verification † | Always active. Requires two trips within 2 minutes or a 30-second continuous trip to alarm. Any other fire zone tripping within 2 minutes also causes alarm. |
| 23 | No Response Type | Special supervisory/activity zone for monitoring. Does not affect arming state. Note: May display as group 13 on Alarm.com. |
| 24 | Silent Burglary | Perimeter-style burglary alarm that reports silently (no panel/bell sound). Instant in Stay or Away. |
| 32 | Remote Device | Designed for the 2GIG Repeater. Supervises tamper, AC loss, low battery, RF jam. |
† Fire/CO groups are not allowed on hardwired loops.
Programming Tips
- Name zones clearly (e.g., “Front Door,” “Kitchen Window Left”).
- Set the correct loop number for each sensor model; trip to learn where possible.
- Use Entry/Exit 2 on paths where users need more time (garage). Keep perimeter instant.
- Keep interior follower for motions so they’re bypassed in Stay but follow entry doors in Away.
- Test each zone from its installed location after programming.

When to Call a Pro
If you’re unsure about life-safety zones (fire/CO), silent vs. audible panic behavior, or reporting formats, talk to a professional.
