to sense the presence of smoke in the duct. Model DNR Air Duct Smoke Detector utilizes photoelectric technology for the detection of smoke. This detection method, when combined with an efficient housing design, samples air passing through the duct and allows detection of a developing hazardous condition. When sufficient smoke is sensed, an alarmFile Size: 1MB

1) Smoke Detectors Most smoke detectors which operate alarms contain an artificially produced radioisotope: americium-241. Americium-241 is made in nuclear reactors, and is a decay product of plutonium-241. Smoke detectors/alarms are important safety devices, because of their obvious potential to save lives and property.

NFPA 90A, 2012, A.6.4 supports this by stating: “Protection provided by the installation of smoke detectors and other related requirements is intended to prevent the distribution of smoke through the supply air duct system and, preferably, to exhaust a significant quantity of smoke to the outside. Neither

A smoke detector alarm is a fire protection device that automatically detects smoke and also gives us warning. In the proposed system, a smoke detector upon senses smoke activates its alarm, sends a low voltage signal to all other smoke detectors in the vicinity. This low voltage signal activates the individual relays in the other smoke
