The Dry Contact sensor is a simple connection to burglar alarms, fire alarms or any application that requires monitoring. Dry contact sensors are user definable and can be used to detect many different inputs such as UPS status, security systems, and air conditioning status.

This sensor plugs into any of our intelligent sensorProbes or securityProbe controllers.

These general purpose switches can be either input or output. When used as an output it can source up to 20 mAmps. You can select the output voltage by setting the Output Level to a Low or a High. When set to Low the pin will output 0 volts. When set as a High the pin will output 5 volts.

When used as an input a switch will retain any error condition until it is read via SNMP. Therefore if a switch encounters a critical condition at any time it must report that condition before it can return to a normal state.

Input pins can be used to detect whether or not an input switch is open or closed. In combination with external sensors, input pins can detect whether a door or window is open or closed, if there is a water incursion and many other conditions.
