The fire detector provides a reliable early warning of a Fire condition responding to fixed threshold smoke concentration detected in the protected premises. The smoke sensitivity (low, middle or high) is in compliance with the European Standard EN54-7 and it is programmed by the fire control panel VIT01. The fire detector operates with an improved algorithm for self-compensation of the optic chamber contamination, signaling the necessity for dusting the chamber. The construction of the optic chamber and the new technology used in the manufacturing of the screen provides high level protection against entering dust particles and insects and working under strong airflow.
The principal, of the optical chamber operation, is based on the dispersion of infrared rays from the smoke particles, trapped in the optical chamber. Communication between the VIT30 and the other VIT components is based on high frequency radio emissions.
