A combination recessed light with a smoke sensor and a carbon monoxide detector to detect for both smoke and carbon monoxide gas in a room. The recessed light can be a wafer style recessed light with an LED light source with a cover plate forming a smoke collection chamber with a smoke detecting sensor located within. A smoke collecting area is located below the LED light source and is connected to the smoke collection chamber thru one or more holes. A box mounted to a wall of the room can have a carbon monoxide sensor, a battery, and speaker, and a test button to sound an alarm for both the smoke sensor and the carbon monoxide sensor. The test button is used to test both the smoke detector and the CO sensor. An array of recessed lights is mounted to a ceiling and a power convertor device converts 110-volt power to 20-volt power that is supplied to each of then LED light sources.

The present invention relates to a system for testing the availability of a detector for detecting smoke. More specifically, the present invention relates to a detector with a testing unit arranged to detect whether the detector has been covered, such that it is unable to perform its function as a smoke detector.

A method of detecting leakage from a central detector unit 2 of an aspirating fire detection system 1 is described. The method includes actuating a valve 8 to block an outlet 8 of the detector unit 2, operating an aspirator 6 of the detector unit 2 at maximum power, and measuring a differential air pressure across the aspirator 6. If the resulting measured air pressure is below a predetermined threshold, it can be inferred that there is a leak within the central detector unit 2 downstream of the aspirator 6.
