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. 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.

Duct mounting is accomplished through a template and 4 sheet metal screws provided. 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. Sl 2000 n 4 wire ionization duct smoke detector sl 2000 p 4 wire photoelectric duct smoke detector. Intake sampling tubes ordered separately are supplied in three standard lengths.

Its primary purpose is to provide early warning of an impending fire and to prevent smoke from circulating throughout the building. If the duct detector receives its power from the fire alarm panel the fire alarm panel can reset the duct detector. The duct smoke detector latches into alarm state when an alarm occurs. For 4 wire detec tors the rts151key a features a multi colored led that alternates between steady green and red.

Remote reset test switches can be accommodated by the sl 2000. The green pilot led will be illuminated and when press. Tor head and depress the cover removal switch sw1 and the unit will be energized. The d4120 and d4p120 leds indicate the status of power maintenance trouble and local alarm conditions.

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