Temperature and Alarm Sensor (FS-TA1)


The Founten Temperature and Alarm Sensor is an add-on accessory to the Founten FS-STAT-32AC or FS-STAT-32ACH. It is connected to the Founten thermostat using 3 wires to provide power and communication. Once connected it provides an input for either an external temperature probe (for temperature monitoring and control) or to add a dry contact input to generate an alarm notification through the Founten Site Manager. The applications where this device can be used are: to detect the temperature inside of an enclosed refrigerator or freezer, to be placed on a wall in a conditioned space with the thermostat installed in a non-visible location, to monitor supply air or outside air temperature, or to interface with a water detector or similar device to generate a notification alert.
