The NOHMI's fire alarm bell provides a higher level of sound with a high efficiency and a lower level of RFI noise.
FMBJ001 fire alarm bell is not compatible with the NOHMI analog addressable fire alarm system.
FMBJ001-D/FBMJ001-DW bells are compatible with both NOHMI analog addressable and conventional fire alarm systems.
It is recommended that fire alarm bells are installed so that the sound level at any place is higher than 65 dB or higher than 6 dB plus the ambient
sound level.
When installing the FMB001/FMBJ001-D in the fire hydrant box, use the fixing plate with the outer frame as it is to increase the sound volume.
When installing the FMBJ001/FMBJ001-D on the wall, please detach the outer frame.
