Title:
FIRE SENSOR AND MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP3878919
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enhance the performance of a fire sensor by increasing the heat storage capacity of a heat storage means.
SOLUTION: This fire sensor comprises a thin plate member 1 having a heat sensitive surface 1a on the outside, temperature detecting elements 53a and 53b arranged inside the thin plate member 1, and a flexible substrate 5 provided separately from the thin plate member 1. A heat storage part 52 is arranged on the flexible substrate 5, and the temperature of the heat storage part 52 is detected by the temperature detecting means 53a and 53b. Preferably, the heat storage part 52 is formed of brass. The temperature detection elements 53a and 53b have low-temperature detecting function and high-temperature detecting function to detect the temperature of the heat storage part 52 and the temperature of heat collecting pads 51b and 51c formed of a material different from the heat storage part 52.
