Thatch temperature monitor

摘要

A temperature monitoring system 1 for a thatched roof 2 comprises a plurality of temperature sensors 3 located within the thatch 2<1>. The sensors 3 are inserted through the lower surface of the thatched roof until the end 4 has reached the centre of the thatch. The sensor ends 4 are located about six inches from the chimney wall 8, as heat transferred from the chimney has been found to be the cause of a number of thatched roof fires. The temperature monitoring system also comprises a monitoring unit 5 comprising an alarm indication means in the form of light-emitting diodes (LED) 6 and an audible alarm 6<1> and also a sensor malfunction indication means in the form of LEDs 7. The monitoring unit 5 has an electrical connection with the temperature sensitive resistors, which are located inside the sensor 3, via two wires 9. The monitoring unit 5 is located within the house. <IMAGE>
