6.4 Digital Inputs
Communicator 2.0 supports an eight dry contact digital input card (found in the External Box) that can be
programmed as normally open / normally closed input. These inputs can be connected to a wide variety
of sensors such as generator operation, magnetic door or window, thermostat, etc.
Wire the devices to the external box.
1. Click the Settings icon, select Alarm System, and click the Digital Input tab.
2. Fill in the following fields:
o
Text message: Enter the text to be sent to the contact(s).
o
Notification delay: Minimum time required to pass before a message is sent.
o
NC/NO: Checking this box means that the contact is Normally Closed.
NC means “Normally Closed”. If there is a change from the usual state (device
opens), an alarm occurs.

closes), an alarm occurs.

Allow to Reset:
When this function is not checked, Communicator 2.0 sends a message to every
contact (in the order given in the priority list) when an alarm is generated.
When checked, Communicator 2.0 sends a message to the first person in the
priority list. If that person acknowledges the message, no further messages are
sent. If the person, does not acknowledge the message, Communicator 2.0
repeats the process and sends a message to the second person on the list.
o
Active: When checked, the alarm function for that digital input is enabled.
