Duct Detector Test Switch Wiring

Duct mounting is accomplished through a template and 4 sheet metal screws provided.

Duct detector test switch wiring.

Its primary purpose is to provide early warning of an impending fire and to prevent smoke from circulating throughout the building. Tor head and depress the cover removal switch sw1 and the unit will be energized. Air velocity test kit with this kit and a suitable manometer testing can be carried out with the duct detector fully installed and wired. However when the duct detector gets its power from the rtu unless there s a remote test switch or an accessible reset button on the detector itself the only way to reset is to cut the power to the rtu.

Yes if the duct detector cannot be reset at the facp or annunciator then a separate test reset station will need to be installed for resetting the duct detector per nfpa 72 section 23 8 5 4 6 4. If the duct detector receives its power from the fire alarm panel the fire alarm panel can reset the duct detector. Sl 2000 n 4 wire ionization duct smoke detector sl 2000 p 4 wire photoelectric duct smoke detector. The superducttwo wire duct smoke detector is ideally suited to applications where early indication of combustion is required within the confined space of ventilation ductwork.

Green indicates power and that the detector board is in place. For 4 wire detec tors the rts151key a features a multi colored led that alternates between steady green and red. Intake sampling tubes ordered separately are supplied in three standard lengths. An exhaust tube of one standard length 7 5 is provided with the detector housing.

The duct smoke detector latches into alarm state when an alarm occurs. Test magnet used to activate test routine from either a sd trm4 remote test reset station or the detector. Remote reset test switches can be accommodated by the sl 2000. For testing the alarm can be enabled by a test button on the power board cover magnet activated test switch or by the optional remote test station.

The system sensor rts151key a is an automatic fire detector accessory de signed to test remotely located duct and beam detectors.
