Abstract
A baffle for concentrating smoke and/or other products of combustion within a smoke detector guard to enhance the performance of detector/guard assembly so that the assembly will be able to pass UL listing testing procedures. The baffle consists of four or more equally spaced fins or blades fabricated from an appropriate material (such as sheet metal), inserted within the smoke detector guard, between the inner wall of the smoke detector guard and the outer surface of the smoke detector housed within the guard. The fins of the concentrator are formed such that there is a gap of no more than one-eighth inch between the edge of the fin and the profile of the outer wall of the smoke detector.
Claims1
Accordingly, what is claimed is that when smoke detector guards, such as the Chase Security Systems, Inc. smoke detector guards are equipped with the Smoke Detector Guard Concentrator and are subsequently tested by Underwriters Laboratories, Inc. (UL) or equivalent testing entity, as an assembly with particular types and models of smoke detectors, the assembly will pass the prescribed UL testing procedures for the smoke detector without a guard, with the particular smoke detector set either in its normal or high sensitivity setting, as may be required for test compliance and appropriate for its intended use, whereas the same smoke detector type and model would not pass the same UL tests when tested as an assembly with the same smoke detector guard that is not equipped with the Smoke Detector Guard Concentrator.
