Bosch FMC-420RW-GSGBU Addressable Analog Glass-Compartment Manual Fire Button, Blue, Surface-Mounted
Product Code: FMC-420RW-GSGBU
An addressable analog manual fire button operating with LSN technology; pressing the black-marked area or breaking the glass compartment initiates the alarm directly. Two isolators in the housing maintain circuit continuity in case of line break or short circuit. Powered by 15-33 VDC, the blue IP54 housing is installed surface-mounted indoors. Each button's unique address allows the panel to identify the exact point from which the alarm originated.
