Optical Smoke Detector

Esser is one of the leading manufacturers of Fire Alarm System, providing a complete Solution for smoke, heat and gas detection with field device options for sounders, flashers and speech.

Optical smoke detector to guarantee safe and early detection of fire. Intelligent fire detector with decentralized intelligence.

Scattered-light smoke detector for reliable early recognition of fires. Responds well to slow-burning, smouldering fires. Intelligent fire detector with decentralized intelligence, automatic function self-test, emergency mode, storage of alarm and operating data, alarm display. Soft addressing and separate operational display is only possible when operating an esserbus / esserbus-PLus IQ8Quad detector without loop isolator, especially for usage in explosion zones. Operation with individual addressing at Ex barrier Part No. 804744 and as standard detector at Ex barrier Part No. 764744.

Intrinsically safe fire detection equipment is defined as “equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmosphere mixture in its most easily ignited concentration”. This basically means that intrinsically safe equipment and wiring operates using electrical and thermal energy below the level that would be required to spark an explosion in a hazardous area such as an oil refinery, Oil Rigs/Platforms, FPSO’s.

Fully addressable devices for installation in hazardous areas with direct connection of the Ex barrier (Part No. 804744) on the loop, without spending a loop address for the connection via a transponder as in case of the conventional connection.

Additional detectors for the explosion zones can be found in the chapters manual call points and special detectors. Detailed information about installation and operation can be found in the documentation (Part No. 798920) on our website.

All of the following IQ8Quad intrinsically safe fire detectors must be operated with the Part No. 805590 base, except for FM approved IQ8Quad intrinsically safe fire detectors, they must be operated with the Part No. 805590.IN. In the case of operation in standard zones, no individual addressing is possible!
