The Valcom V-A2416B is a 16-inch round analog clock with a black finish, designed for surface mounting in facilities that use a centralized synchronized clock system. The microprocessor-based movement accepts multiple communication protocols — from basic sync-wire to the advanced Valcom 2-wire digital protocol — selected in the field without replacing the clock. The 2-wire digital protocol streams data continuously over the same two conductors that carry power, constantly checking and correcting every clock simultaneously to guarantee that no clock in the system drifts from the others. The Telecom Spot Expert Review Schools, hospitals, and government buildings with dozens or hundreds of analog clocks have long struggled with drift — clocks that read slightly different times in different rooms. The V-A2416B addresses that through continuous data streaming rather than occasional sync pulses. The 2-wire protocol checks each clock constantly, not just at scheduled intervals, so a power blip that causes one clock to reset is corrected within seconds rather than remaining wrong until the next midnight reset. The field-selectable protocol is a practical installation benefit: if the facility later upgrades its clock head-end from sync-wire to the Valcom 2-wire system, the clocks themselves do not need to be replaced — only the head-end hardware changes.
