Yes, Tellink UCC includes Digital Inputs to be connected to the outputs of other external devices within the Cabinet. If an open door sensor is connected to one of the Digital Inputs then the system will register this situation, with a time stamp, and will be able to send an alarm message if this has been programmed.

The previous procedure can be applied to any external device equipped with low -voltage status indication outputs, which is connected to the Digital Inputs of the UCC, such as Differential Relays, photocells or any other type of sensor. Some of the Digital inputs of the UCC additionally allow pulse counting capabilities when connected to external devices equipped with S0 pulse outputs.
