Product overview
The VES VF5664 VES95A dual priority switch monitor provides two contact-monitoring inputs on one module. It reports the documented input states and supports Class A or Class B field-wiring arrangements. The module is polarity sensitive, and current consumption depends on the input and LED condition. Select the compatible panel, input configuration, end-of-line components and metal mounting box as part of the complete installation.

Applications
Compatible addressable designs needing two independent contact-monitoring channels with priority response. Confirm the programmed input functions and wiring supervision for the connected devices.
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.
