The Simplex 6310-9122A is a 12-inch round impulse clock engineered for legacy Simplex master clock systems operating on the 3510 Hz signal format with 3-prong connector compatibility. Unlike standard 2-wire synchronized clocks, this model is specifically designed for older Simplex installations that output the 3510 Hz impulse signal.

The 12-inch dial ensures clear readability in institutional and commercial environments. This clock maintains precise synchronization with compatible master systems, making it essential for facilities with established Simplex infrastructure. Ideal for schools, hospitals, offices, and industrial settings requiring reliable timekeeping across networked clock systems.
