摘要： A photoelectric smoke detector includes an optics cover that provides a smoke chamber that has a smoke chamber opening, a blocking component is mounted to the optics cover. An inner cover provides a first opening and a second opening. The first opening receives a portion of the blocking component and the second opening is aligned with the smoke chamber opening. A spoiler is received against the inner cover. The spoiler includes at least one of: a U-shaped fin arrangement and a Y-shaped fin arrangement.

摘要： A detection device includes a cover member adapted to support a detector assembly having a plurality of pins. A base member of the detection device is coupled to the cover member and, is adapted to accommodate a plurality of electrical terminals adapted to be engaged with the pins. The detection device includes a rotatable ring disposed on the base member and adapted to lock the cover member with respect to the base member. The detection device includes a plurality of shorting elements disposed on the rotatable ring and adapted to form a shorting contact with the electrical terminals. The rotatable ring is rotated with respect to the base member and the cover member to at least one of lock the cover member with respect to the base member and break the shorting contact, and unlock the cover member with respect to the base member and form the shorting contact.

摘要： A trim element for covering a base portion of a smoke detector is disclosed. The trim element includes a hollow housing comprising an inner wall adapted to removably attach the hollow housing to the base portion of the smoke detector. The hollow housing defines an outlet in fluid communication with an aerosolizing chamber. The aerosolizing chamber includes an aerosol generator, an airflow generating element for directing airflow in combination with the generated aerosol towards the outlet, and a processor electrically coupled to the aerosol generator and the airflow generating element. The processor receives an input signal indicative of an inspection mode of the smoke detector and transmits an activation signal to the aerosol generator and the airflow generating element in response to receiving the input signal.

摘要： A detection chamber assembly of a smoke detector is provided. The detection chamber assembly includes upper and lower covers, louvers and a corrugated bug screen. The louvers are arranged with the upper and lower covers to define a chamber bound between the upper and lower covers and the louvers. The louvers include a first pair of louvers defining a first space therebetween to permit fluidic ingress to the chamber and a second pair of louvers defining a second space therebetween to permit fluidic ingress to the chamber. The second space is wider than the first space. The corrugated bug screen includes a body disposed about the louvers and a mesh corrugation feature coupled to the body at the second space to permit fluidic ingress to the chamber at the second space and to inhibit bug ingress to the chamber at the second space.

摘要： A life safety detector comprising a housing defining a dark photo detection chamber for receiving ambient material, at least one light source configured to emit light into the detection chamber, at least one light sensing device operable to receive light reflected from the ambient materials in the detection chamber; and a processing device coupled to the at least one light sensing device. In a first mode of operation, the light received by the at least one light sensing device within the dark photo detection chamber is indicative of smoke, and in a second mode of operation, the light received by the at least one light sensing device within the dark photo detection chamber is indicative of an indoor air quality.
