OPU-3 P is a robust, surface-mounted enclosure, made of white ABS plastic. Owing to its aesthetic appearance, the enclosure can be installed in conspicuous locations in usable space interiors. The enclosure base can be recessed into the wall so that the enclosure proper can occupy less space. Its neutral design and ample size make it possible to install inside the enclosure many types of SATEL control panels, their extension modules, communication modules, controllers and a large number of other devices. Installation and maintenance of the system components is further facilitated by using special mounting panels. OPU-3 P is provided with double tamper protection against opening the enclosure and tearing it off the wall.

The enclosure has sufficient space for installation of 40VA or 60VA network transformers, and can also accommodate a 7 Ah or 17 Ah, 12 V backup battery. As it neither blocks nor weakens the radio signal, wireless devices including their antennas can be installed inside the enclosure.
