The D350P and D350RP addressable photoelectric duct smoke detectors are used exclusively with the Fire•Lite MS-9200 and MS-9600 addressable fire alarm control panels. Since these duct detectors are addressable, they will help emergency personnel quickly locate a fire during its early stages, potentially saving precious rescue time while also reducing property damage. The D350RP offers the same features as the D350P while adding a Form-C relay. An HVAC system supplies conditioned air to virtually every area of a building. Smoke introduced into this air duct system is thus distributed to the entire building. Smoke detectors for use in air duct systems sense the presence of smoke in the duct.
The D350P and D350RP air duct smoke detectors are photoelectric detectors, combining this detection technology with an efficient housing design that samples air passing through the duct, allowing detection of a developing hazardous condition. When sufficient smoke is sensed, an alarm signal is initiated at the fire control panel monitoring the detector. With the D350RP, appropriate action can be taken to shut off fans and blowers and to change over air handling systems, etc. This can isolate toxic smoke and fire gases or prevent their distribution thoughout areas served by the duct system. Two LED’s on each detector light to provide a local, visible alarm indication. A remote alarm output is provided for use with auxiliary devices. The D350P and D350RP have remote test capability with the RTS451/RTS451KEY Remote Test Station, as well as remote communication using the RA400Z alarm LED.
Duct smoke detectors have the following limitations:
• NOT a substitute for open area smoke detectors.
• NOT a substitute for early warning detection.
• NOT a replacement for a building’s regular fire detection system.
