Product overview
The VES VF8140 and VF8141 provide monitored 24 V DC power with battery charging for compatible fire alarm equipment. Cabinet depth determines battery accommodation, while the stated total output, continuous load and charging ratings describe different limits. Select the cabinet, battery capacity and connected equipment together, and verify the complete current budget rather than adding the independent headline ratings.

Applications
Compatible fire alarm power and notification-circuit expansion requiring supervised supplies, calculated load and standby capacity, and the documented circuit arrangements.
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.
