Duct detector test switch wiring.

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. Air velocity test kit with this kit and a suitable manometer testing can be carried out with the duct detector fully installed and wired. Intake sampling tubes ordered separately are supplied in three standard lengths. 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.

Green indicates power and that the detector board is in place. An exhaust tube of one standard length 7 5 is provided with the detector housing. Its primary purpose is to provide early warning of an impending fire and to prevent smoke from circulating throughout the building. 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.

For 4 wire detec tors the rts151key a features a multi colored led that alternates between steady green and red. The system sensor rts151key a is an automatic fire detector accessory de signed to test remotely located duct and beam detectors. The duct smoke detector latches into alarm state when an alarm occurs.

Duct mounting is accomplished through a template and 4 sheet metal screws provided. If the duct detector receives its power from the fire alarm panel the fire alarm panel can reset the duct detector. The d4120 and d4p120 leds indicate the status of power maintenance trouble and local alarm conditions. 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.

Test magnet used to activate test routine from either a sd trm4 remote test reset station or the detector.
