The Series MB Motor Bells provide a better engineered motor bell for fire and life safety alarm systems. The motor for the Series MB Motor Bells is a durable, high torque permanent magnet motor selected for its high performance and long life.
Series MB Motor Bells
Distributed Architecture
All FC-250 modules operate independently. There is no central operating system, no central point of failure. Processing power is distributed throughout the campus, increasing system survivability, eliminating home-run wiring costs while decreasing downtime due to system maintenance.
Highly Survivable
Since NAC’s and SLC’s are grouped on the same module and events are processed locally, ALM modules will perform local operations even if network communication has been severed. Distributed modules also minimize campus-wide downtime by restricting maintenance to the local module.
These DC vibrating Series MB Motor Bells are offered in 6” and 10” shell sizes in both 12 and 24 VDC models. The RSSP Sync/Non-Sync retrofit plates are used in conjunction with the Series MB Motor Bell when combination appliances are required. The RSSP retrofit plates are available with either Multi-Candela or single candela strobes and easily mount to a 4” square or SBL-2 backbox.

The alarm appliances shall be Harding Series MB vibrating Motor Bells or approved equal. They shall be UL Standard 464 Listed for Fire Protective Service. Shells shall be aluminum in 6” or 10” diameter. Sound output at 10 feet shall be 92 dBA. The bells shall incorporate a permanent magnet motor and suppression circuitry to minimize RFI. They shall include a built-in trimplate for semi-flush mounting to a standard 4” square backbox, or surface mounting to Harding’s indoor BB backbox or outdoor WBB backbox.
For bell strobe applications, retrofit plates Harding Series RSSP with Multi-Candela or Single Candela strobes shall be used. All bell models shall be polarized for line supervision and shall have screw terminals for in-out field wiring of #12 to #18 AWG wire. Operating voltage shall be nominal 24 VDC or 12 VDC. Finish on all models shall be textured enamel
