Conventional Heat Detector

ZI-H 717

In environments where there is humidity, dust and pollutants other than smoke from the fire, the ideal option is to use heat detectors. Depending on the environment, two types of classes S and R can be defined for the detector operation; Type S: Performance relative to constant temperature threshold only and Type R: Combined performance relative to constant temperature threshold and sudden changes in ambient temperature. The definition of the above classes is done according to EN 54-5 standard.

Double-layer metallized fiberglass circuit with moisture, vapor and corrosion resistant layer
Production of electronic boards using modern equipment based on SMT technology
False Alarm Probability Technology (F.A.P)
Detection of ambient temperature increase in two modes of constant (class A1S) and incremental (class A2R) in accordance with EN 54-5

Conventional Heat Detector ZI-H 717

Features that can be mentioned about the ZI-H 717 heat detectors are: Heat resistant ABS body; Dual-mode function indicator with 360-degree visibility (green flash: normal mode and solid red: alarm mode); Predict enough space behind the detector to enter the zone wires and remote indicator; Double elevator terminals; Reverse polarity protection; Double-layer metallized fiberglass circuit with moisture, vapor and corrosion resistant coating; SMT technology for assembling electronic components; And chrome plating of all metal parts to protect against rust.


Immunity to the effects of electromagnetic noise has been achieved using ZITEX specialized F.A.P technology. This technology has been obtained with software (specialized programming of microprocessors) and hardware and has greatly increased the performance reliability of the detector. It is also possible to connect to the remote in this detector model. Thermal classes R and S are included in the production of detectors, so different types of detectors can be used for different environments.

Golden guarantee and fast and available hardware and software after-sales service are common features of all ZITEX products. In the process of design, production, testing and quality control of this product, the latest and most modern equipment and machines have been used. Similar to other thermal detectors, Iranian National Standard No. 3710 (which is the product standard license based on this standard) and the international standard EN 54-5 have been considered in the design and manufacture of this product. The product authenticity tracking code is inserted in a 16-digit serial number on the back of the product and allows the customer to control the authenticity of the product.
