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.
