Cooling unit Digital voice system Fire alarm system line of bundled precision video coaxial cables includes Cat 5e cables that provide solutions for internet telephone, networking, IR control, audio/ video and automation. The 3-coax has a 23 AWG center conductor that provides higher performance than stranded. (Signal® by Coleman Cable) www.colemancable.com #6 H Cooling unit for data centers and small computer rooms places cooling next to the heat source. The unit is able to support power densities as high as 70 kW per rack when used with hot air containment systems. The model’s design eliminates the need for constant speed fans, which saves energy and maximizes power. (InfraStrXure InRow RP cooling unit by American Power Conversion) www.apc.com #7 A a built-in temperature/humidity sensor, 10 dry-contact points for door switches, clogged filter alarms and generator alarms and two serial ports. (Liebert vEM-14 by Emerson Network Power) www.liebert.com #8 0.1 µA resolution for AC/DC current. It also features 8:1 distance to target ratio with 0.95-fixed emissivity. (EX470 by Extech) www.extech.com #10 Digital voice system delivers emergency notification by offering digital audio evacuation, paging and firefighter telephone systems. The device allows facility managers to broadcast multiple messages through an entire facility using recorded message phrases. The device integrates with modern fire alarm control panels to provide network-wide audio distribution and paging. It also supports as many as five channels of digital telephone operation for firefighters. (XLS3000 by Honeywell) www.honeywell.com #9 F A F Fire alarm systems support any combination of 50 intelligent sensors or modules. It offers extensive programmability that cuts alarm response time between manual pull station and strobe activation to as little as 0.25 seconds. The systems feature peer-to-peer, intelligent and bi-directional communication between the control panel and devices, and between the devices themselves. (CyberCat 50 by Fike Corp.) www.fike.com #11 P Thermostatic tempering device limits water temperature to fittings for fixtures such as sinks, lavatories or bathtubs. The water must completely pass over the thermal motor before discharge thus ensuring that delivery temperature will be maintained even with water flow far below rated capacity. (Max Line ASSE 1070 Thermostatic Tempering Device by Symmons) www.symmons.com #12 Monitoring device combines Multimeter/IR thermometer network-enabled environmental monitoring with power management. It delivers a comprehensive view of conditions within a small data center to prevent overheating and power overload. The device is equipped with sensor inputs: with a built-in non-contact IR laser thermometer measures surface temperatures ranging from -4°F to 520°F. The device is rated CAT III-600 volts and provides highresolution measurements, including 0.1 mV resolution for AC/DC voltage and Monitoring device Multimeter/IR thermometer Thermostatic tempering device Consulting-Specifying Engineer • AUGUST, 2007 49 http://www.extech.com http://www.liebert.com http://www.colemancable.com http://www.fike.com http://www.apc.com http://www.honeywell.com http://www.symmons.com
