DoorTek 301-IM - Reader Interface Module

The 301-IM is part of DoorTek’s 300-IM Hardware Line. The system allows the designer to combine Reader Modules (301-IM), Input Modules (303-IM) and Outputs Modules (305-IM) as needed to meet the requirements of the application. The standard 301-IM can be configured in 2, 4, and 8 door combinations through multiple communication options.

An individual 301-IM can be configured to control a door as well as arming and disarming alarms, triggering HVAC or lighting controls.
