Conventional Smoke Detector

ZI-S 820

The most widely used fire alarm product in buildings is the smoke detector. The first sign of a fire is the smoke from it, and its timely detection can prevent the loss of life and property.
Zitex ZI-S 820 Smoke Detector, by processing photoelectric signals, detects the presence of white and black smoke in the environment at high speed and warns. The body of this detector is designed and manufactured using specialized heat-resistant ABS. Two-way 360-degree function indicator (flashing green in normal mode and solid red in fire mode) allows the detector to be viewed from all angles. Enough space provided behind the detector, as well as the use of double elevator terminals, ensures standard wiring.

Conventional Smoke Detector

ZI-S 820

The technical features of this detector model include specialized lockable chamber and dust protection filter, reverse polarity protection, reflector box and environmental noise control processors to eliminate false alarms (F.A.P technology) and specialized real smoke detection processors. He pointed out briefly.

Chrome plating has been applied to all metal parts to protect them from rust. The circuit of this detector is of metallic fiberglass type and the technology of assembling electronic components on it is SMT. To have optimal performance in the worst climatic conditions, a layer resistant to moisture and corrosive materials is predicted on the circuit.

Multi-stage design, production and quality control is performed by the latest laboratory machines and equipment. In addition, the golden warranty and after-sales service of fast and available hardware and software have made the end consumer not have to worry about supporting their fire alarm systems. To control the authenticity of the product, an exclusive tracking code is provided on the product label. Product design and manufacturing standard is the national standard of Iran No. 3708 and 3709 and the international standard EN 54-7.
