CONVENTIONAL MULTICRITERIA OPTICAL + A1R RATE OF RISE DETECTOR CODE CE.S2000
The multi-criteria conventional detectors (optical + A1R rate of rise) are certified by Certifying Body authorized (BRE Global Limited & LPCB + VdS), pursuant to the standards EN 54-5:2000 + A1: 2002, EN 54-7:2000 + A1: 2002 + A2: 2006, CEA 4021:2003.
The production is carried out by applying a quality control system, which includes a series of rules regarding the construction of all the devices.
The multicriteria A1R rate of rise + optical detector combines conventional optical detection, based on light scattering in a patented optical chamber, and the detection by a thermal sensing element. It performs a continuous sampling of the particles of air and of the temperature variation in the area to be protected to provide in the shortest possible time, through a particular algorithm, the fire detection system, ensuring a high immunity to false alarms.
A thermistor positioned centrally supervises the ambient temperature rises slowly.
In particular, the thermal component of the detector is of class A1R which provides for an intervention at a temperature of 58 ° C, temperature at the attainment of which the detector generates an alarm signal in the presence of very small increases in temperature.
Each sensor is equipped with a red LED positioned centrally in order to ensure a 360 ° visibility.
The fully symmetrical structure of the cap and of the optical chamber ensure a good flow of air from all directions and provide an inherent immunity to ambient light.
The design "Double Dust Trap" provides protection from contamination by dust and by the external light, thanks to a special labyrinth for the entry of the smoke, delaying the need for maintenance without reducing the efficiency of the detector.
The external screen provides high protection against insects.
It also features a tamper device from the base - mechanical tamper.
To verify the correct operation of the sensor, all models can be tested after installation, simply by using a suitable magnet.
Cyclically, the sensors perform a complete test of all functionality.
The housing "Decorline" allows the use of detectors in environments with special aesthetic requirements.
