Description
Equipped with the I/O module (DCU), the controller supports configurable digital inputs, alarm dry-contacts and
site sensor ports for environment management and alarms reporting. The DCU user interface module provides
the ability to add multiple sensors for: ambient temperature, humidity, water, door status, smoke and battery
temperature. The dry contact alarms are configurable and can be customized upon the DC system's requirements.
All alarms can be easily configured and monitored remotely through the WebUI (Web User Interface).
