Conventional Duct Sampling Unit

The Conventional Duct Sampling Unit is designed to monitor levels of smoke in air ducts operating at airspeeds of 0.5 to 20 meters per second. It can be fitted to any wall of a ventilation duct and has two tubes that extend into the duct through punched holes. 

• Weather-resistant enclosure.
• Sampling pipes are available in 4 lengths.
• Clear cover means the alarm LED is visible at all times.
• Sampling and exhaust pipes are fitted to the backbox without the need for tools.
• Cover is monitored to ensure working integrity and if removed, a fault appears.
• Easily accessible wire clamping terminals ensure secure and fast termination.
• Self-sealing test port allows the dispensing of test smoke via a needle into the duct smoke detector allowing you to test without removing the cover. 
• Volt-free normally opened or closed non-latching relay contact, the relay energises when a detector is in alarm (Available only with Ampac Orbis option).
