The 2GIG
®
FT100-345 Wireless Flood/Temp Sensor is a
fully supervised and tamper protected 345 MHz sensor that
will monitor the ambient temperature of a space for high or
low temperature thresholds and report if changes outside
of the defined settings are detected. It also has the ability
to detect and report the presence of standing water in the
immediate sensor location. The sensor transmits in non-
encrypted mode by default, and can be set to encrypted
mode via an on-board switch.
