Astra-3731

Wireless temperature detector

The detector is designed to measure the temperature at the installation site and transmit by radio to the Security Hub.
Temperature control is carried out using a built-in temperature sensor and / or a DS 18B20 temperature sensor (not included in the delivery set) connected to the detector terminal block. Maximum cable length - 3 m

The detector is designed to measure the temperature at the installation site and transmit by radio to the Security Hub.

Maximum cable length - 3 m

Features

  • terminal block for connecting an external temperature sensor DS 18B20 (not included in the delivery set). The maximum cable length is 3 m;
  • lithium-thionyl-chloride battery, size AA, voltage 3.6 V, included in the delivery set;
  • control of supply voltage. The detector measures and transmits via the radio channel the value of the residual capacitance of the battery simultaneously with the temperature measurement results;
  • average battery lifetime - 5 years.
