Sentinel Installation and Setup Guide
2.8K/10K TEMPERATURE SENSORS
The Sentinel is compatible with 2.8K/10K temperature sensors that match the curve data listed in the

to 57ºC) and the 10K thermistor is -87° to 168°F (-66° to 76°C). Temperature sensors can be connected 
directly to the zone terminals without regard for polarity. Choose an alarm input and connect the wires 
to the corresponding screw terminals for that zone. 2.8K and 10K temperature sensors are available 
from Sensaphone. See Appendix C for part numbers. The figure below shows how to connect a tempera-
ture sensor:

4–20MA CURRENT LOOP TRANSDUCERS
The inputs on the Sentinel are compatible with transducers that produce an analog output current of 4 
to 20mA. Such transducers are available to measure tank and well levels, extreme temperatures, air pres-
sure, water pressure, flow, voltage, current, rotational speed, etc. Contact our technical support depart-
ment for assistance regarding your monitoring requirements (877-373-2700 or
