Title:
HEAT SENSOR
Document Type and Number:
Japanese Patent JPH10188157
Kind Code:
A
Abstract:
To provide a heat sensor capable of detecting the room temperature of many sensing areas and outputting fire detection signals at a low cost.
This heat sensor used for a fire reporting device is provided with at least two temperature detection means SA for detecting the room temperature of the different sensing areas and a signal processing means SB for processing respective temperature signals inputted from the temperature detection means SA and outputting the fire detection signals and the signal processing means SB outputs the fire detection signals based on a temperature detected by one of the temperature detection means SA.
