JA-157P dual zone outdoor wireless motion detector – curtain
It is a dual zone outdoor detector by Optex with a 5°angular width detection zone which makes it very suitable for guarding narrow spaces such as balconies, French doors, terraces, etc.
It is supplemented with a transmitter compatible with the JABLOTRON 100 system. The device is equipped with dual-beam optics with a high immunity against false alarms and the detection of small animals. The detector has an anti-masking function – i.e. protection against shielding its view.
The detector is also equipped with three tamper contacts. One on the detecting part and the next two on the transmitter part with both of them immediately reporting tampering of the detector or removal from the installation place.
