Wheelock MB Series Motor Bells
Description
Wheelock’s Series MB Motor Bells provide a better engineered motor bell for fire and life safety alarm systems. The Wheelock Series MB Bells include higher dBA, low current draw, built-in trimplate for semi-flush mounting, low frequency aluminum shells, and low RFI noise. The motor for Series MB Bells is a durable, high torque permanent magnet motor selected for its high performance and long life. Series RSSP Sync/Non-Sync retrofit plates are used in conjunction with the Series MB Motor Bell when combination appliances are required. The Series 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 Series 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) and UL Standard 1971 (Signaling Devices for the Hearing Impaired). The Series RSSP retrofit plates may be synchronized when installed with the Wheelock Series SM, DSM, Sync Modules or a Power Supply with Wheelock’s patented sync protocol. Wheelock’s synchronized strobes offer an easy way to comply with ADA requirements concerning photo-sensitive epilepsy.
Features
• High sound output with low current draw. • Low frequency aluminum shells for better audibility through walls, doors and other structures. • 6” and 10” shell sizes in 12 or 24 VDC models. • Integral RFI suppression to minimize included noise on the NAC circuit. • Mounting options for surface, semi-flush, outdoor, and concealed conduit installation. • Built-in trimplate makes semiflush mounting simpler and less expensive • Polarized for DC supervision of NAC circuits. • Operates on filtered or unfiltered DC.
