This custom DC-802T-DN-BCD-ANDON Seconds Countdown Timer<\/strong> was built for the Overhead Door Company of Bowling Green<\/a> to serve as a highly visible and audible warning system for a loading dock door that is about to close. Designed to improve workplace safety and situational awareness, this unit provides workers with a clear countdown so they know exactly when the door cycle is ending, reducing surprises and helping prevent accidents in busy dock environments.<\/p>\n\n\n\n

The timer features a simple yet reliable two-digit countdown capable of timing from 1 to 99 seconds<\/strong>. Time is set using BCD rotary switches<\/strong> located at the bottom of the enclosure, allowing quick, tool-based adjustments without opening the housing. Each switch corresponds to a digit position\u2014seconds units and seconds tens\u2014making setup intuitive and precise. Once triggered, the display begins counting down immediately, giving dock personnel a clear visual cue as the door approaches closure.<\/p>\n\n\n\n

To support flexible integration with existing door and control systems, the unit includes a close contact wire junction box<\/strong> on the left side of the enclosure. This junction box provides pigtail wiring for start, stop, and reset functions<\/strong>, allowing the timer to be activated by door controls, relays, or automation systems. Inputs support both contact closure and PNP signals (5\u201330 VDC)<\/strong>, making this timer adaptable across a wide range of industrial applications.<\/p>\n\n\n\n

At the end of the countdown, the DC-802T-DN-BCD-ANDON delivers unmistakable alerts. When the display reaches zero, an adjustable IP-67 rated piezo buzzer<\/strong> sounds for three seconds while the LED display flashes. At the same time, the IP-67 ANDON light mounted on top of the enclosure flashes in unison<\/strong>, providing a clear visual warning that the door is closing or has reached the end of its cycle. The flashing indication remains active until a reset signal is received, ensuring the alert is not missed in noisy or high-traffic environments.<\/p>\n\n\n\n

Built for both indoor and outdoor use, this timer is housed in a sealed, all-aluminum IP-66 enclosure<\/strong> with a durable black powder-coated finish. The enclosure is fingerprint resistant, dust resistant, and waterproof, making it suitable for loading docks exposed to weather, debris, and temperature changes. An integrated bright\/dim switch<\/strong> allows the display to remain clearly visible in full sunlight while preventing glare in low-light conditions.<\/p>\n\n\n\n

The large 8-inch oval LED digits<\/strong> are readable from distances of up to 400 feet<\/strong>, ensuring visibility across wide dock areas. Mounting flexibility is provided through adjustable aluminum C-channel mounting rails<\/strong>, allowing installers to drill mounting holes based on the specific surface or structure at the site.<\/p>\n\n\n\n
