  • SYSTEMS AND METHODS FOR DELAYING OR ACTIVATING A BLOWOUT DEVICE OR A PURGE DEVICE IN A SAMPLING PIPE NETWORK OF AN ASPIRATED SMOKE DETECTION SYSTEM
    Publication number: 20190005805
    Abstract: Systems and methods for delaying or activating a blowout device in a sampling pipe network of an aspirated smoke detection system are provided. Some systems can include an aspirated smoke detector, a sampling pipe coupled to the aspirated smoke detector, a blowout device coupled to the sampling pipe, and a delay device coupled to the blowout device. Responsive to the aspirated smoke detector detecting a triggering event, the delay device can delay the blowout device from performing a blowout action in the sampling pipe or can instruct the blowout device to perform the blowout action in the sampling pipe.

  • Multi-channel aspirated smoke detector
    Patent number: 9373238
    Abstract: An aspirated smoke detector includes a manifold coupled to a smoke sensing chamber of the smoke detector. The manifold couples ambient smoke from a plurality of locations to the smoke sensing chamber. A location of the origin of the smoke can be determined by associating a member of a plurality of a different type of smoke sensor with each of the locations. When smoke is detected in the sensing chamber, the members of the plurality can be interrogated to determine the location of the origin of the smoke in the sensing chamber.
