Product overview
The VES VF5669 XP95A ionization smoke sensor measures changes in an ionization chamber and sends the processed condition to compatible control equipment. The two-wire loop carries power and data, and a compatible base provides the field connection and optional remote-indicator terminals. Selection must account for airflow, the expected fire signature and the handling requirements of the documented radioactive sensing element. Confirm current panel compatibility and local acceptance for the specific installation.

Applications
Compatible smoke-detection designs where ionization sensing is selected for the expected fire conditions. Include suitable maintenance, handling and end-of-life arrangements for the exact device.
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.
