The PPS-150 is a fence-top mounted intrusion detector, consisting of a set of 8 transmitter/receiver pairs, each with a maximum range of 50 meters. If necessary, the amount of pairs can be pre-ordered accordingly.

							PPS-150	Detection zone pattern

Upon detection of an intrusion the PPS-150 outputs an alarm through a normally closed dry relay contact, by opening it. The pps-150 is unique in its ability to operate both as a complete system and as individual pairs. Multiple zones allow for higher precision in locating the intrusion and for the conservation of power as all detector pairs use the same 12volt DC external power supply.
