This wireless, motion detector is powered off of a single 9-volt battery. It sends a signal to the base unit when motion is detected. This is ideal for a staircase or open room. When motion is detected, it trips the alarm.
Typical detection range is 15 to 20 feet.
You may use an UNLIMITED number of motion detectors in your security system. Order 2 or 20--they all interface into the same alarm base unit.
This motion detector is 100% wireless. There are no wires to run. Installation is quick and easy and will take less than 5 minutes.
You may use an unlimited number of any combination of add-ons. However, the base unit (SSC-ALM1) is REQUIRED for any of the add-ons to function.
