Smoke detectors operate on the principle of light scattering caused by smoke particles in the air.
The detector has the function of automatic gain control; a microcontroller calculates the reading compensation to maintain a constant sensitivity over time, correcting for any increase in level caused by dust settling inside the analysis cell.
Smoke detectors should be installed in places where there are no air currents that could divert the flow of particles produced by combustion and in places where normal activities carried out do not produce fires of gaseous materials.
The 1043/501 digital optical smoke detector with microprocessor and short-circuit isolator offers the highest reliability and accuracy for smoke detection based on the Tyndall effect. A specific algorithm supervises smoke density by filtering out false alarms, performs calculation and storage of the reference value of "drift compensation," which is updated exclusively by command from the central unit.
This product automatically stores, in its nonvolatile memory, the thirty measurements preceding and 30 measurements following an alarm condition. These measurements can be displayed, in graphical or textual form, on the central unit's display. This feature is very important for retrospectively analyzing the condition of the detector before and after the alarm condition has been detected. The two-color LED, in operating conditions, indicates the detector status while, in service mode, it can be used to display the detector address via a function activated by the control panel.
