KT-300
Two-reader networkable door controller
The KT-300 runs two card readers, either on two separate doors or on one door for entry and exit. Controllers link together over an RS-485 bus so the system can grow with your building, and firmware updates go out from the EntraPass workstation instead of a visit to every panel.
- 2Readers per controller
- 8Monitored inputs, expandable to 16
- 12 hMax. battery backup
- UL 294Certified
Key features
- Controls two readers on two doors, or entry and exit on one door
- Links with other KT-100, KT-300 and KT-400 controllers on an RS-485 loop
- Firmware updates from any EntraPass workstation thanks to flash memory
- Detects communication speed up to 115,200 baud and sets its own address, with no DIP switches or jumpers
- Supervises lock circuits for shorts and opens, and reports low or missing battery
- Arms and disarms an external intrusion alarm with a card at the reader
- Expands with Combus modules for relays, inputs, outputs and an LCD time and date display
- Adds LAN/WAN connectivity with the KT-IP module
