Features
- Parameter driven multisensor detector
O2T multisensor fire detector IQ8Quad Ex (i) w/o isolator
Intelligent detector with two integrated optical smoke sensors with different scattered-light angles as well as additional heat detector sensor evaluation for the recognition of smoldering fires up to open fires with uniform characteristics. Comparison of the heat sensor signals for smoke classification and reduction of false alarms by interferences, e.g. from steam or dust. Due to its excellent detection characteristics, and enhanced false alarm management, the detector is also able to recognize TF1 and TF6 test fires, described in the standards. The O²T intelligent detector is also suitable for a higher operating temperature of up to +65 °C. Used when early and reliable fire detection is requested. 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. Consider that the change of parameter settings for environmental adaption is reserved to the Non-Ex automatic detectors.

Additional information
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!
For usage in zone 1 and zone 2 in case of operation
- with individual addressing the Ex barrier Part No. 804744,
- in conventional zones the Ex barrier Part No. 764744 must be used!
The Ex barrier separates intrinsically safe and non-intrinsically safe circuits before the explosion prone area to be monitored (explosion zone).
To determine the battery capacity of a FACP, the detector data "Quiescent current @ FACP battery" can be added.
