This is a pet immune PIR sensor which means that small animals up to 25KG can be left in the room and not have to worry about getting any false alarms while the alarm is armed. This battery powered pet immune PIR sensor connects back to your WatchGuard 2020 base station using wireless technology so that you can be informed as soon as an intruder is detected.
This PIR sensor also includes a tamper switch to let you know if it is being moved. To help minimize false alarms this PIR sensor includes automatic temperature compensation and anti-draft technology. The sensor is powered by 2xAA batteries and the low battery alert will let you know when they need changing.
