Alarm Zone Planner
A panel groups sensors into zones so it can tell you where a trigger came from — and so you can arm the perimeter at night while you sleep inside. Enter your sensors, the perimeter split and the number of floors, then pick how to group them, to size the zones and the panel. Planning figures; runs in your browser.
- Perimeter sensors (skin)12
- Interior sensors (inside)10
- Night / stay set (armed while you sleep)12 on the perimeter
Planning estimate only — zone counts depend on your panel’s addressing, wiring and how finely you want to see the map. Keep entry/exit doors on their own zone with an entry delay; a stay/night mode arms the perimeter while you are inside. Wireless panels expand zones via expanders; hardwired zones map 1:1 to cable runs — label every zone. Confirm against the product datasheet and a site walk-through with your installer.

How likely is your alarm to cry wolf? Toggle known false-alarm causes — pets, sensors near vents, single-tech detectors, no entry delay — for a red / amber / green risk score and the fix for each. Persistent false alarms can get your monitoring response suspended.
