DUO Technology

It allows two-way communication, that is, the wireless sensor is capable of sending and receiving data from the alarm panel. The DUO Technology offers more security to the alarm system, in addition to increasing the battery life of the detectors.

Greater detection

With its special lens, the detector possesses a wide detection area, analysing an angle of up to 115°.

Animal Immunity

PETs don’t need to be left outside so that the security system can be armed. With the animal immunity feature, the intelligent detector does not detect small animals, that is, there is no detection, no alarm activations.
