Rittal brings proven protection for data centres
Rittal has updated and optimised the DET-AC product family. The fire alarm and extinguisher system using the 3M NOVEC™ 1230 fire suppression solution is suitable for use inside server enclosures. It was the first system in its class to successfully pass comprehensive VdS testing.
The DET-AC III product family comprises the DET-AC III Master fire alarm and extinguisher system, the complementary DET-AC III Slave unit, and the EFD III early fire detection solution. All three are available in the form of 19’’ slide-in racks.
Rittal has made significant enhancements to the DET-AC III Master. In addition to VdS testing, the system now features a CAN bus interface for direct integration with the Rittal CMC (Computer Multi Control) III monitoring solution. This provides administrators with much more detailed information on the status of installations and on incoming alerts. This means administrators can read error messages on a PC instead of on individual devices, and can immediately take appropriate action. The new USB interface greatly simplifies service and maintenance of the DET-AC III. For example, service technicians can even view information on operational status and events, modify configurations, reset service intervals, or install new firmware from a laptop – so they do not need to open the enclosures.
The DET-AC (Detection Active) III Master active extinguishing system was designed for use in server enclosures, and only takes up one U in a 19’’ system. The solution features a two-stage smoke extraction system. Two highly sensitive optical sensors detect even the smallest smoke particles at very early stages – and can sound an alarm from 0.25 per cent obscuration per meter. If the first sensor detects smoke aerosols, a pre-alarm is issued. If the second sensor also detects smoke, the main alarm is triggered, and the extinguisher is activated.
The systems use the Novec™1230 fire suppression solution from 3M. It is environmentally friendly, does not conduct electricity, and does not damage IT equipment. Using the stored medium, DET-AC III Master can extinguish volumes up to 2.8 m³. In conjunction with up to four DET-AC III slave units, it can monitor and suppress fires in up to five server enclosures.
The global rebound in construction activity is set to continue over the coming years, supported by a wave of publicly funded infrastructure projects. This investment is coming at a time when global supply chain disruptions are hampering the delivery of construction materials, and tight labour markets are limiting the supply of labour.
Epiroc, a leading productivity and sustainability partner for the mining and infrastructure industries, will relocate the production and development of drill rigs for surface construction from Japan to its facility in Nanjing, China. The production facility in Yokohama, Japan, has been sold and will be closed.
