Our flood and temperature sensor is a fully supervised, tamper-protected, one-way 345 MHz sensor that monitors ambient temperature and detects a wet/dry flood condition. The sensor reports wet/dry conditions and temperature to the panel. Once the sensor probe detects the presence of water for three minutes, the integral transmitter will send a wet alarm transmission to the security/control panel. The probe will also send a restore (dry) report when the presence of liquid is no longer detected by the flood probe for three minutes. For flood reporting, the sensor requires the installation of the supplied external flood probe. The sensor is capable of detecting clean or dirty fresh water, salt water or tap water.
