Rack Extinguisher System

Rack extinguisher system DET-AC Plus, 1 U with integral early fire detection This compact rack extinguisher system DET-AC Plus (Detection Active Plus) is designed for use in the Rittal IT rack, fitted in the 482.6 mm (19˝) level. The system is equipped with a 2-stage smoke analysis extractor system. A bayed rack may optionally be included in the monitoring and extinguisher system. The system is also suitable for use in racks with bayed air/water heat exchangers (Liquid Cooling Package, LCP). The ecofriendly, non-toxic Novec1) 1230 is used as the extinguisher medium, which means that this extinguisher system is suitable for universal use. Undamaged, active hardware (servers, active network technology) is not impaired by the extinguisher medium. Thanks to the extremely sensitive detection of smoke, even in racks with a high level of climate control (airflow speed), this ensures that there is plenty of time to forward an alarm message either acoustically, optically via the LC display on the enclosure front, or by connecting the integral floating contacts to the building management system or fire alarm centre and to the Rittal monitoring system CMC-TC. When opening an enclosure door, activation of the extinguisher system is blocked by the two access sensors (door monitoring). In order to ensure that proper functioning of the system is maintained even in the event of a power failure, an emergency back-up power supply with a stored energy time of 4 hours is integrated into the system. The system can also be supplied purely as an early fire detection system without the extinguisher medium tank.
