Description
The Valcom V-D2440B is a 4.0-inch digital clock designed for synchronized timekeeping in schools, offices, government agencies, healthcare facilities, manufacturing plants, and transportation hubs. The four-digit hour/minute display uses 4-inch numerals visible from across a hallway or large room, and the Valcom 2-wire digital communication protocol keeps every clock in the system synchronized simultaneously. Multi-function software allows the communication protocol to be selected in the field, giving installers flexibility to match the existing time distribution infrastructure without replacing head-end equipment.
The Telecom Spot Expert Review
The V-D2440B fits into the Valcom synchronized clock ecosystem, working with the V-VCU clock driver, V-DCPI digital clock protocol interface, V-GPS receiver, and V-WMC wireless module. The microprocessor-based movement and field-selectable protocol are what set this clock apart from commodity digital clocks: the facility can choose anything from a basic sync-wire protocol to the advanced Valcom 2-wire digital stream, which mixes power and synchronization data on the same two conductors for simplified wiring. The 4-inch digit size targets spaces with longer viewing distances where smaller displays would be unreadable from across the room.
