The Wheelock MB motor bells provide a specifically designed motor bell for fire and life safety alarm systems. The Wheelock MB bells include higher dBA, low current draw, built-in trim plate for semi-flush mounting, low frequency aluminum shells, and low RFI noise. The motor for MB bells is a durable, high-torque permanent magnet motor selected for its high performance and long life.

These DC vibrating 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 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 Wheelock SBL-2 backbox. All RSSP strobe appliances meet or exceed the requirements of NFPA 72 (National Fire Alarm Code), ANSI 117.1 (American National Standard for Accessible and Usable Buildings and Facilities), ADA (Americans with Disabilities Act), UL Standard 1971 (Signaling Devices for the Hearing Impaired).

The RSSP retrofit plates may be synchronized when installed with the Wheelock Series DSM, Sync Modules or Wheelock Power Supplies with Wheelock patented sync protocol. Wheelock synchronized strobes offer an easy way to comply with ADA requirements concerning photo-sensitive epilepsy.
