DS-K27M01

Key Features

• Designed with 3 types of distributed access controller: single-door distributed access controller, two-door distributed access controller, and four-door distributed access controller.
• Adopts the modular design for the convenient maintenance.
• Equipped with 2 RS-485 interfaces for the uplink communication (RS-485 communication) with the master access controller. 2 RS-485 interfaces forms 1 RS-485 loop.
• Equipped with 1 TCP/IP 10M/100M self-adaptive network interface for the uplink communication (TCP/IP communication) with the master access controller.
• Supports being connected to the card reader via RS-485 interface or Wiegand interface.
• Supports RS-485 loop, formed by 2 RS-485 interfaces, for the RS-485 communication with the card reader, and supports loop power fault detection and redundant function.
• Supports W26 and W34 for the Wiegand communication with the third-party card readers.
• Supports online working mode and offline working mode. In the online mode, it supports the permissions of the master access controller for the access control. In the offline mode, it supports the offline permissions of the master access controller for the access control. The offline permissions are downloaded to the distributed access controller via the memory.
• Supports storing 20,000 legal cards and 60,000 pieces of offline event records.
• Supports offline card parameters configuration and offline templates configuration. Permissions of 255 week plans, 8 periods per day, 1024 holiday schedules, and 255 holiday groups can be configured.
• Supports the zone short circuited alarm and the zone disconnected alarm.
• Designed with two batteries, providing separated power supply for the electric lock and the control panel.
• Supports the fire-fighting linkage.
• Supports backup batteries, watchdog, and tamper-proof functions.
• Equipped with a built-in RTC, and supports NTP synchronization and remote synchronization.
• Supports the standby storage battery, and supports the low battery alarm.
• Supports the USB port to upgrade the controller, import/export the configuration parameters or card permission parameters, and export the card swiping records.
• Supports the online upgrade. If upgrading failed, the controller still can work by the original program, and the controller will auto re-upgrade when it is restarted.
• Designed with independent power switch, communication indicator, running indicator, and abnormal indicator.
• Designed with 19-inch 3U chassis, which can be put into the cabinet or applies to the wall mounting.
• Supports IP 54
