Frequently Asked Questions
Q: Why install a detector inside the duct?
A: Duct smoke detectors shut down HVAC fans when smoke enters the air system, preventing smoke from spreading between floors and zones of a building.
Q: How is it installed?
A: The detector mounts on the duct with a sampling tube across the airflow; drilling and sealing follow the installation manual to maintain duct integrity.
Q: Does it connect to the fire alarm panel?
A: Yes. Relay outputs drive fan shutdown and alarm signalling, and addressable versions report as supervised points on the Wanlin loop.
Q: What duct sizes are supported?
A: Sampling tubes from 150 to 600 mm cover most rectangular and round ducts; multiple tubes and detectors serve large air handlers.
Q: Can it be tested remotely?
A: Yes. A remote test feature and optional remote indicator allow testing without opening the unit, simplifying maintenance checks.
