The Silent Knight SD500-PSDA is a dual action addressable fire pull station. The SD500-PSDA Addressable Fire Pull Station is a normally open initiating point that is compatible with Honeywell Silent Knight and Farenhyt Series addressable fire alarm control panels (FACP).
In fact, the SD500-PSDA Addressable Fire Pull Station is designed for indoor use in non-explosive environments. Also, the SD500-PSDA Addressable Fire Pull Station is used to activate a non-coded alarm instantly. An on-board status LED is visible from the front of the pull station. Furthermore, the LED flashes to indicate proper communication with the FACP (approximately every 30 seconds). Besides, the pull station mounts to a standard single gang electrical switch box or a surface mount back box P/N PS-SMBB. In addition, the SD500-LK is used to convert the SD500-PS (single action pull station) to an SD500-PSDA (Dual-action pull station).
