Access control kit for four doors. The kit consists of metal enclosure with power supply, networked access controller and IO expander. The controlled doors can be managed on both, read-in and read-out side, by RS485 (MCT series readers). In case the RACS CLK/DTA (PRT series readers) or Wiegand readers are used, doors can be controlled on read-in side only. Each controlled door has separate 0.2A supply output for readers and 1.0A supply output for lock and other door equipment. The back-up battery charging current can be set to 0.3A, 0.6A or 0.9A. Entire system is supplied from the power supply included in the kit.
