3 Thedetector housing shall be UL listed per UL 268 Aspecifically for use in air handling systems. The detectorshall operate at air velocities of 500 feet per minute to4000 feet per minute. The Detector housing shall beequipped with an integral mounting base capable ofaccommodating either photoelectronic or ionizationdetector heads. It shall be capable of local testing viamagnetic switch or remote testing using the RTS451 KEYR emote Test Station. The duct Detector housing shallincorporate an airtight Smoke chamber in compliance withUL 268A, Standard for Smoke detectors for DuctApplications. The housing shall be capable of mounting toeither rectangular or round ducts without adapterbrackets. An integral filter system shall be included toreduce dust and residue effects on Detector and housing,thereby reducing maintenance and servicing. Samplingtubes shall be installed after the housing is mounted to theduct by passing through the duct housing.
