Wheelock Series MB Motor Bells provide a better engineering motor bell for fire and life safety alarm systems. 24 VDC, 6" SHELL, RED.
These Wheelock motor bells use a high‑quality, micro‑motor operating mechanism. This provides long-term reliability, low starting voltage, and extremely low current consumption. These features enable the use of more bells per circuit and greater alarm signal distribution than conventional bells. The low starting voltage provides a stronger signal on marginal circuits.
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.
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 semi-flush mounting simpler and less expensive
- Screw terminals permit fast in-out field wiring of #12 to 18 AWG wire
- Polarized for DC supervision of NAC circuits
- Operates on filtered or unfiltered DC
