Reader should be mounted on a vertical piece of supporting structure, usually wall, away from
sources of heat and moisture.
The rear panel should be mounted with use of delivered screws in orientation shown on
installation drawings so that tamper lever touched the surface and firmly pressed the tamper
switch.
The reader enclosure consists of a front and rear panel. Before installation it is necessary to
separate them by means of included key or flat screwdriver according to fig. 6.
It is recommended to install PRT82MF reader on a flush type box 60mm diameter.
PRT12MF-DES reader is delivered with additional extended base panel which is intended to be
used when reader is installed on metal surface and/or if there is a need for extra space for
connection wires.
Any electrical connections should be done without any voltages.
When using separate power supply sources for the reader and the controller it is necessary to
short both GND terminals. Do not short 12V terminals.
The front panel of PRT82MF/PRT84MF reader should be periodically cleaned with a slightly
moistened cloth and soft detergent. It is forbidden to use abrasives and heavy duty detergents
such as alcohols, solvents, gasoline etc. Damage caused by improper maintenance is not
covered by warranty.
