The optical smoke fire detector provides reliable early warning of a Fire condition responding to fixed threshold smoke concentration detected in the protected premises.
The smoke sensitivity is factory preset in accordance with European Standard EN54-7.
The fire detector is controlled by a microprocessor. FSS operates with an improved algorithm for self-compensation of the optic chamber contamination, signaling the necessity for dusting the chamber. It is done quickly due to the easy dismantling and assembling of the body cover.
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 insect and working under strong air flow.
