Product overview
The VES VF2042, VF2043 and VF2044 are legacy conventional photoelectric smoke detector references. The manufacturer compatibility sheet for the VF2050 and VF2051 bases identifies these detector models as discontinued. This page preserves model-specific technical information for existing installations and replacement discussions; it does not establish current production, availability or suitability of a substitute. Confirm the installed panel, base, detector revision and replacement path with UDCT.

Applications
Identification and technical review of existing installations using these discontinued models. Any replacement requires confirmation of the compatible listed panel and base arrangement.
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.
