FIELD: fire signaling equipment engineering, in particular, engineering of thermal fire alarms, possible use for detecting fire by increase in temperature of environment in place where alarm is mounted. ^ SUBSTANCE: fire alarm uses three thermo-sensitive elements, made on thermo-resistors, which have varying constant of time needed for change for resistance during change of temperature (thermal inertia). ^ EFFECT: stabilization of inertia process, achieved due to adaptation of activation temperature during slow change of environment temperature in absence of fire. ^ 4 dwg |
