CONNECTING SENSORS
The Web600 is compatible with a wide variety of sensors including normally open/normally closed con-
tacts, 2.8K and 10K temperature sensors, and 4–20mA current sources. Contact Sensaphone or your
Sensaphone reseller for assistance in selecting sensors for your monitoring requirements. A list of sen-

GENERAL WIRING CONSIDERATIONS
Most dry contact sensors can be connected to the Web600 using inexpensive 2-conductor twisted-pair
cable as small as #24 AWG. For temperature and 4–20mA sensors, use the wire chart below as a refer-
ence for selecting the appropriate wire gauge. Note that if the sensor is located far from the unit or if you
are running cable in an electrically noisy environment, you should seriously consider using twisted pair
shielded cable. This will shield the signal from electrical interference, thereby preventing false readings
and/or damage to the unit. For your convenience, Sensaphone has 22 gauge shielded cable available in
50’ lengths (part number FGD-0010). To minimize electrical noise coupling between sensor wires and
other wiring, follow the guidelines listed below:
