Product overview
The VES VF4022 and VF4032 combine a wall-mounted evacuation speaker with visual strobe notification. Field-selectable speaker voltage and power taps allow the audio load to be coordinated with a compatible voice system, while the selected model determines adjustable or fixed candela output. Speaker loading and strobe current are separate calculations. Select the appliance, synchronization interface and mounting arrangement together with the project sound-coverage, intelligibility and visual-notification design.

Applications
Indoor audio and visual fire alarm notification using compatible voice-evacuation and strobe circuits. Confirm power tap, candela, synchronization and installation height for the approved coverage design.
Selection and project integration
Share the fire alarm drawings, equipment schedule, compatible panel platform and cause-and-effect requirements with UDCT. Selection should confirm device protocols, supported interfaces, circuit supervision, power and standby calculations, and the exact enclosure or module arrangement.
Use the current manufacturer documentation to check compatibility, wiring limits, software requirements and approval scope. Commissioning should verify the configured alarm, fault, indication and control functions as part of the complete system. Remote reporting also requires a compatible receiving service and confirmation of local network availability.
