Fire Safety & Security Products OH720, OP720, HI720, HI722 Cerberus® PRO Automatic fire detectors For the automatic addressable detector bus C-NET z The optimum smoke detector for all applications z Signal processing with detection algorithms z Automatic address allocation during commissioning z Reliable detection of emerging fires z Suitable for air speeds up to 5 m/s for OH720 and OP720 z Communication via C-NET (individual addressing)

Fire Safety & Security Products Characteristics z Environmental – ecologically processing – recyclable materials – electronic and synthetic material simply separable z Characteristics – resistant to environment and interference factors such as dust, fibers, insects, humid- ity, extreme temperatures, electro-magnetic interference, corrosive vapors, vibration – insensitive to impact, tamper protection – protected electronics, high-quality components – integrated short-circuit isolator, which locate the defective part on the detector bus of the control unit and insulates between 2 detectors – built-in alarm indicator (AI), visible at 360° – up to 2 external alarm indicators of type DJ1191/DJ1192 connectable per detector – signal processing with detection algorithms – automatic address allocation during commissioning – the same detector base type can be used for each detector type, for surface and re- cess supply wiring z Optional accessories – Detector locking device LP720 as protection against theft Designation plate FDBZ291 – Detector base seal RS720 for higher protection category – Micro terminal DBZ1190-AA (0.28… 0.5 mm 2) – Connection terminal DBZ1190-AB (1.0… 2.5 mm 2) – Sounder base DBS720 OH720 Multi-sensor smoke detector Multi-sensor smoke detector consist of: – Detector – Dust cap to cover the detector for protection against dust during construction work Function – works according to the scattered light principle with one sensor, optical forward scattering – Opto-electronic sampling chamber holds off disturbing extraneous light but opti- mally detects smoke particles – an additional heat sensor increases the fire detector’s immunity to deceptive phe- nomena – selectable detection behavior by different parameter sets – immunity against transient false alarm causes Application – for the detection of flaming fires caused by the combustion of liquid and solid mat- ters, as well as smoldering fires – for reliable fire detection in environments with deceptive phenomena

Fire Safety & Security Products OP720 Smoke detector Smoke detector consist of: – Detector – Dust cap to cover the detector for protection against dust during construction work Function – works according to the scattered light principle with one sensor, optical forward scattering – Opto-electronic sampling chamber holds off disturbing extraneous light but opti- mally detects smoke particles – selectable detection behavior by different parameter sets Application – for the detection of smoke-generating flaming and smoldering fires HI720 Heat detector (static+RoR) Heat detector consist of: – Detector – Dust cap to cover the detector for protection against dust during construction work Function – equipped with one heat sensor – for high requirements – certain response behavior with slow and fast temperature increases, also by depth temperature – selectable detection behavior by different parameter sets Application – suitable in areas in which occur different environment temperatures – where high dust or dirt developments or large humidity which can the impact of conventional alarm units to impair HI722 Heat detector (static) Heat detector consist of: – Detector – Dust cap to cover the detector for protection against dust during construction work Function – equipped with one heat sensor – measures the ambient temperature, when the maximum temperature is exceeded the detector sends a danger signal to the fire control panel Application – suitable in areas, in which temporary high variations in temperature arise – where high dirt and heat fluctuation which can the impact of conventional alarm units to impair
