DoorTek 303-IM - Input Interface Module
The 303-IM is Part of DoorTek’s 300-IM Hardware Line.. It provides high density, configurable inputs for monitoring sensors including door contacts, motion detectors, glass break sensors, temperatures alarms, fire alarm panel outputs and other systems that need to be supervised and have their real-time status displayed.
This controller is part of a modular system that allows the designer to combine readers (301-IM), inputs (303-IM) and outputs (305-IM) as needed to meet the requirements of the application.
