To extend the range of coverage/control of the alarm system in our home and create an impenetrable and invisible anti-intrusion curtain, with extreme simplicity. This additional universal wireless infrared volumetric sensor for the alarm control unit comes complete with an installation kit. Wall installation must be carried out at a transit point, where any intrusive movement in the area covered by the infrared rays causes the control unit to send the alarm signal. The sensor is powered by an internal 9 Volt battery.
