Alert Inputs
There are three inputs that can be used to connect to a variety of wired sensors, such as a
sump pump monitor or alarm door contacts.
To use this feature, wire the dry contacts of a sensor or switch to the terminals of one of the
inputs. The two terminals labeled IN1 are for alert input 1, IN2 for alert input 2, and IN3 for
alert input 3.
The Settings page on the Web Portal is used to assign the inputs to a zone, and configure

Do not connect an Alert input to any external voltage source. Dry
contacts only. Failure to do so may cause equipment damage.
