Bosch FMC-420RW-HSRRD Addressable Resettable Fire Alarm Button, Surface Mounted, Outdoor, Red
Product Code: FMC-420RW-HSRRD
Outdoor-type button with resettable trigger; occupies a single address on the LSNi ring and sends alarm directly. Its IP67 class housing operates between -25 and 70 °C, making it suitable for placement at harbors, open warehouses, and site entrances. Activation status is read from the LED indicator. Its ability to reset without glass replacement eliminates spare parts tracking at outdoor test points used several times per year.
