FLOOD AND TEMPERATURE DETECTOR

INSTALLATION INSTRUCTIONS

The 2GIG-FT1-345 is a fully supervised, tamper protected one-way 345 MHz 
sensor. It will monitor the ambient temperature and/or will detect a wet/dry 

fl

 ood 

condi  on. The sensor reports wet/dry condi  ons and temperature to the panel.

Flood Conditions

Once the sensor probe detects the presence of water for three (3) minutes, the 
integral transmi   er will send a wet alarm transmission to the panel. The probe will 
also send a restore (dry) report when the presence of liquid is no longer detected 
by the 

fl

 ood probe for three (3) minutes. For 

fl

 ood repor  ng the sensor requires 

the installa  on of the supplied external 

fl

 ood probe. The sensor is capable of 

detec  ng clean or dirty fresh water, salt water, or tap water.

Temperature Conditions

Heat:

1.  If the temperature is more than 95° F (35°C) for 

fi

 ve (5) minutes, the sensor 

will send a loop 2 transmission.

2.  If the temperature is less than 95°F (35°C) for 

fi

 ve (5) minutes, the sensor will 

send a loop 2 clear.

Cold:

1.  If the temperature is less than 41°F (5°C) for 

fi

 ve (5) minutes, the sensor will 

send a loop 3 transmission.

2.  In the temperature is more than 41°F (5°C) for 

fi

 ve (5) minutes, the sensor 

will send a loop 3 clear.
