PR312MF Outdoor Access Controller with Keypad Description: The PR312MF/PR312MF-BK outdoor access controller is a single-door controller used within the RACS 4 access control system, designed for the most popular access control solutions. It can be used in both standalone and networked installations for up to 4,000 users. All PRxx2 series controllers are equipped with an RS485 communication interface, which can be used for both programming and network communication. An access control system based on PRxx2 controllers can be managed locally via COM/USB serial ports or remotely via a WAN/LAN computer network. The controller has a built-in MIFARE 13.56 MHz card reader. The device is equipped with three programmable NO/NC inputs, two programmable transistor outputs, and one relay output. The PR312MF model has a built-in keypad. Connecting the device to a CPR control panel adds additional features to the controller. Can be installed directly on a 60mm electrical junction box. Controller Programming: The controllers have the factory-set ID address 00 and are pre-programmed with a MASTER card, which is supplied with new devices. This card can be used for initial testing of the device immediately after installation. The device is programmed from a computer using PR Master software. Connecting the controller to a computer requires the use of an appropriate communication interface: UT-2USB, UT-4DR, or RUD-1, or the CPR32-NET-BRD control panel. Alternatively, PRxx2 series controllers can be manually programmed using keyboard commands described in the manual. Later, so-called Programming Cards can be used to program the device. Programming Cards are standard proximity cards assigned specific programming functions during configuration. Installation: The controller can be installed both indoors and outdoors and does not require additional protection against precipitation or moisture. All electrical connections should be made with the power supply disconnected. All devices connected to the RS485 communication bus of the access control system should have a common negative power supply (GND). To ensure this, the negatives of all power supplies used in the system should be connected. Access Controller Tasks: The primary task of access controllers is to make decisions related to the controlled door. The door's operational logic and decisions are based on configuration data stored in the controllers' internal memory. Decisions include access rights, time schedules, system arming modes, alarm status signaling, and more.
