Bells

Wheelock® MB Motor Bell

Wheelock® MB motor bells provide a better engineered motor bell for fire and life safety alarm systems.

Wheelock® MB motor bells provide a better engineered motor bell for fire and life safety alarm systems. These bells include higher decibels, low-current draw, built-in trimplate for semi-flush mounting, low frequency aluminum shells, and low RFI noise. The motor is a durable, high-torque permanent magnet motor selected for its high performance and long life. These DC vibrating bells feature a 10 inch shell size with an input voltage of 24V DC.

Features & Benefits:
  • High sound output with low-current draw
  • Low frequency aluminum shells for better audibility through walls, doors, and other structures
  • Integral RFI suppression to minimize included noise on the notification appliance circuits (NACs)
  • Mounting options for surface, semi-flush, outdoor, and concealed conduit installation
  • Built-in trimplate makes semi-flush mounting simpler and less expensive
  • Screw terminals permit fast in-out field wiring of 18 to AWG wire
  • Polarized for DC supervision of NAC circuits
  • Operates on filtered or unfiltered DC
