Bosch FMC-120-DKM-H-B Conventional Outdoor Manual Fire Button, Blue

A manual alarm button with indirect actuation (Type B) connected to conventional detection lines. After alarm is given, the mechanical blocking of the locking mechanism remains in place, allowing maintenance personnel to identify which button was pressed. The IP54 protected blue enclosure operates between -25 and 70 °C, allowing it to be left in open areas. A second contact leading to panel control enables monitoring of button status from a separate terminal.
