The EC20RRU-3 rate-of-rise detector is well suited to areas such as kitchens and shower The EC Series of low-profile plug-in smoke and heat detectors rooms, where the ambient temperature is relatively constant, measure-up to the quality and performance standards that but where steam and smoke are present. The EC20FTU-3 have made Edwards fire detection products the industry’s fixed-temperature detector is ideal for laundries and industries best price-performance buy available today. Meticulously where fluctuations in ambient temperature is expected. engineered to deliver high-performance features, superb reliability, and unbeatable quality, the EC Series is a low-cost Edwards recommends that all detectors be installed according solution for conventional detection applications. to the latest recognized edition of national and local fire alarm codes. The EC30U-3 photoelectric detector distinguishes itself as a performance leader in its class with its highly stable design that The installation and maintenance advantages of EC Series resists air movements caused by heating and air conditioning, detectors add value to these products throughout their service and changing environmental conditions. This makes it a reliable life. Their twist-and-lock design makes short work of installation performer ideally suited to modern building interiors. and maintenance operations. A plastic breakout on the detector housing optionally prevents removal from the base except with The EC10U-3 ionization detector distinguishes itself as a a special tool. performance leader in its class with automatic compensation that dramatically reduces the risk of nuisance alarms caused by A bright, easy-to-see LED on the detector glows steady when it changes in temperature, humidity and atmospheric pressure. is in alarm, thus eliminating much of the guesswork responding While many comparable detectors routinely fall into alarm or to front-panel indications. If a detector is removed for any trouble states when these conditions fluctuate, the EC10U-3 reason while the panel is in its normal state, a zone trouble automatically compensates without compromising detection condition will result. This ensures the integrity of the alarm performance. The net result is a degree of reliability unparalleled system at all times. among conventional detectors on the market today. continues...
