The JA-87P is designed to indicate disturbances outside the building caused by human bodies. 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. It is supplemented with a transmitter compatible with JA-8x OASiS systems. Both the detector and the transmitter are powered by a lithium battery. The common power supply is beneficial as the low battery signal is transmitted to a control panel as standard. The detector is equipped with three TAMPER contacts (at the front on the detection part and the front and rear on the transmission part), which immediately report opening of the detector cover or its tearing from the place of installation. The detector can also have the anti-masking function activated. From the Oasis control panel’s point of view, it is a classic detector with all the properties this system uses. The detector reports its current status via control transmissions to the system.
