Rittal updates DET-AC III product range for fire detection and extinguishing
DET-AC III range
Rittal has updated the DET-AC III product range, comprising 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 products are available in the form of 19in slide-in racks.
Significant enhancements have been made to the DET-AC III master. 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 more detailed information on the status of installations and incoming alerts.
A USB interface is said to simplify service and maintenance of the DET-AC III. It allows service technicians to view information on operational status and events, modify configurations, reset service intervals or install new firmware from a laptop, without opening the enclosure.
Taking up 1U in a 19in rack featuring a two-stage smoke extraction system, two highly sensitive optical sensors detect small smoke particles at 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.
Using the 3M Novec 1230 fire suppression solution, the system was the first in its class to successfully pass comprehensive VdS testing. It is environmentally friendly, does not conduct electricity and does not damage IT equipment.
Rittal has expanded its modular TS IT rack to offer more than 100 configurations, providing customers with more options and greater flexibility for their IT enclosures. The range of enclosures comprises a selection of dimensions that can be combined with a choice of interior components.
For switchgear with ratings above 1,600A, air circuit breakers (ACBs) and copper connections have to be tested for short circuit and the effects of heat rise. Rittal’s latest RPE software (version 6.2) can supply the actual current-carry capacity (Inc) of all leading ACB manufacturers, plus the CAD drawings of the ACB connections required to fit within the Ri4Power modular switchgear systems.
The development of a power station plant room not only provided logistical and technical issues but also harsh environmental considerations for Nova Controls during its installation of a water treatment PLC for a Yorkshire biomass site. The performance of Rittal’s Ri4power modular switchgear busbar system helped to deliver the solution that the site demanded.
Rittal is offering a large range of cooling products that are suitable for addressing the problem of overheating panels. The company’s TopTherm fan-and-filter units, for example, provide an energy efficient means of cooling enclosures but require a clean and cool environment to operate effectively.
An efficient IT infrastructure is now at the core of every modern business, but underneath the tiers of applications and operating systems a robust and reliable platform is essential. Rittal claims that its TS IT system provides optimum stability and maximum space utilisation thanks to its welded frame construction.
