With advancements in traditional equipment performance and new product technologies, facility management capabilities seem endless.
Today's time switches offer far more flexibility, user-friendliness, and features than in the past. The number of applications is limited only by your imagination and ingenuity. Time switches do more than turn lights on and off at preset times; they're excellent for controlling windows, window blinds, doors, heaters, pumps, and other equipment. With today's multi-switch output circuits, one switch can control two or more devices, eliminating the need to buy two separate units.
Among the new features in lighting timers is a warning flicker that alerts occupants the lights will soon be turned off, thus increasing both safety and comfort. Today, some switches feature selectable manual control with automatic daylight savings time changeover. This feature is far more affordable than in the recent past, due to technological advances. Advances have even made this feature available in a seven-day time switch, where it was formerly available only in a 365-day switch. The new seven-day switch will automatically advance the hour in the spring and set it back in the fall, without requiring the user to program for a year at a time.
The combination time and photo-eye switch makes for intelligent control of awnings, shades, and lights. For example, the switch will open the shades for more light and, if that source is insufficient, will brighten the indoor lights. This is especially useful with the delay timing functions and dusk/dawn sensing features being designed into many units. Light sensitivities cover an extremely wide range.
Spot fire detectors are more sensitive than ever - as low as 0.003% obscuration, a level formerly achievable only with active aspiration. A key element in this success is the use of lasers. Laser use, in turn, has been made practical through significant advances in electronics that eliminate what would have been a plethora of false alarms. An extremely low level of obscuration allows systems to detect fires in the precombustion stage, giving more time for difficult evacuations. The best detectors discriminate dust from smoke. Obviously, this reduces false alarms, but less obviously, it also provides the ability to monitor dust levels. This is very helpful in cases of toxic building syndrome or in the presence of dust-sensitive processes.
Fire control systems continue to incorporate more features, pre-alarm and alarm levels, integration with other systems, and user-friendliness. Systems have made quantum leaps in artificial intelligence. For example, some "self-learn" the pre-alarm parameters and automatically set thresholds just above peak noise levels.
Fire control networks now monitor multiple buildings on multiple sites and provide a common graphical user interface (GUI) that makes a hodgepodge of separate systems appear as one to a central operator. Most systems run on a standard 32-bit true multitasking GUI-oriented operating system known for its stability, robustness, security, and popularity in higher-end applications. The level of reporting and control (including elevators, CCTV, PA, PLCs, energy systems, parking, lighting, video, etc.) surpasses previous capabilities. One fascinating aspect is the ability to extract zoom areas, device identification, icons, controls, and locations directly from CAD drawings in as much detail and precision as the CAD drawings themselves allow. Such is the stuff a fire chiefs dreams are made of.
