InnovairFlex addressable and conventional duct detectors
As close control air conditioning systems for computer and IT rooms and air conditioning systems for personal spaces become increasingly common throughout Europe, the risk of fire or smoke spreading through the duct systems they use to transfer the warm and cold air increases.
System Sensor Europe has developed new detectors to provide specific fire protection for the square and circular air conditioning ducts that form part of such systems. The new range of InnovairFlex™ range Duct detectors consist of conventional and addressable versions. The addressable version uses the Series 200 Advanced optical detector and the conventional the Series 300 optical detector. Both ranges offer class-leading false alarm rejection through a combination of advanced hardware and software engineering. The unique air management design of the sensor cover allows the units to monitor ducts with air velocities ranging from 100 to 4000 ft/min without an increased false alarm risk. Both versions can be fitted with a module to control ancillary equipment; the module is mounted in the
unit, saving the cost of an additional conduit box and extra wiring. Uniquely, the housing is made up of two interconnected sections that are hinged together, allowing them to be installed in rectangular or square configurations to suit the space available. To simplify installation, the air sampling tubes can be installed, replaced or removed from either the front or the rear of the unit with a large termination area giving plenty of room for cables. InnovairFlex has a very wide operating temperature and humidity range, allowing the units to be installed in aggressive environments such as machine rooms, roof voids and other spaces where the temperature and humidity excursions are likely to be extreme.

Tyco Electronics announces MRJ21 Ultra Slim Gigabit Ethernet Cabling System
The AMP NETCONNECT business unit of Tyco Electronics announces the general availability of its reduced diameter MRJ21 Ultra Slim Gigabit Ethernet cabling system. The trimmed-down MRJ21 Ultra Slim cable assembly is 9.14 mm in diameter, weighs 40% less than comparable four- pair cabling systems, occupies 45% less rack space, requires 25% less power per port, and promises to help to reduce data- centre operating costs.
The MRJ21 Ultra Slim cable assembly is a major development in the structured cabling marketplace, especially for data- centre customers who are seeking to optimise space in the rack, on the floor, and throughout cable pathways. “Our MRJ21 Ultra Slim cabling system is the thinnest copper Gigabit Ethernet solution available from Tyco Electronics”, comments David Richens, Senior System Application Engineer at Tyco Electronics: “We are excited to bring this innovative cabling technology to our customers and to the marketplace. It is the perfect solution for today’s server-crowded data centres where space is a premium.” He adds: “Tighter IT budgets coupled with escalating power costs are driving technology selection. In this context, the design of our MRJ21 ultra slim cable improves airflow, dissipates heat more efficiently and reduces overall

power consumption.” Installation of the
MRJ21 Ultra Slim cabling system is six to ten times faster than four-pair cabling, with significant reductions in the cable management and routing problems of bundled cabling systems. Engineered to support more ports per rack, the lean MRJ21 Ultra Slim cabling system supports six ports of Gigabit Ethernet interface, which dramatically increases the number of ports
customers can include in a single rack. Whereas traditional four-pair cable bundles add weight and create clutter, the MRJ21 Ultra Slim cabling system reduces cable mass, bend radius and weight without sacrificing performance.
