Abstract: A baffle system for concentrating smoke and/or other products of combustion within a smoke detector guard. The baffle consists of four or more equally spaced fins, plates 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 cover or housing located 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. The baffle fins, plates or blades form narrowing chambers between the interior walls and bottom of the smoke detector guard and the exterior of the smoke detector cover or housing that direct and concentrate the atmosphere entering through openings in the smoke detector guard to openings in the smoke detector cover or housing, decreasing the response time of the assembly to products of combustion in the atmosphere.

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.
