Description
The rate-of-rise heat detector, HS-WS 19L, is designed to sense the rapid or abnormal rise in temperature of air. If ambient temperature rises rapidly, the air in chamber expands and prosses the diaphram to close the contact point to give advanced warning. when a slower temperature change occours, the expanded air escapes through a bleeding hole to keep the preassure balanced so that the fault alarm never occours.
