The IR-4000 is the wireless PIR (passive infrared) sensor from Alarm Australia. With a wireless range of up to 1600m (1.6km)* and full compatibility with any of our 4000 series portable receiver and base receiver, the IR-4000 will allow you to monitor many locations that were difficult before..

The passive infrared detector is able to monitor an area up to 100° wide. With the integral mask, the detection area can be narrowed down to 20°C or anywhere in between. With the swivel mount, the IR-4000 sensor can be adjusted right to left up to 80°C and up and down up to 50°C. With three different sensitivity settings, the IR-4000 can detect a person up to 3m, 7m or 12metres away. The sensor can also be set to flash an LED or stay dark when a signal is sent. The IR-4000 is powered by one 9 volt battery and will have a battery life of about 12 months under normal conditions. There is also a double chime low battery alert to notify you when it is time to replace the battery. The IR-4000 is designed for indoor or light duty outdoor applications under an eave, awning or other protected location like a small unattended office.
