Monitoring inputs

2022-07-29Last updated

You can use the four inputs on the Synergis™ Cloud Link appliance to monitor external events in the access control system.

The monitoring inputs can be configured by software as supervised or unsupervised, each requiring a specific resistor configuration.
Note: Synergis Cloud Link inputs must not be used as REX (Request To Exit) in UL294-compliant installations.
