Silent Knight SK-PULL-DA is a dual-action addressable manual pull station for Silent Knight addressable fire alarm systems. It requires two motions to activate, which helps reduce accidental activations while keeping manual alarm initiation fast. Each station is individually addressable, so the control panel identifies the exact location of an alarm.
The installer can open the station without causing an alarm condition. A dual-color LED visible through the handle blinks green in normal operation and stays steady red in alarm. The handle latches in the down position and the word "Activated" appears, clearly showing the station has been pulled. A key-operated test and reset lock uses a key that matches compatible Silent Knight FACP locks. Rotary address switches speed installation, and Braille text on the handle supports accessibility.
