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.
