DA-655 Mier Hard-Wired Drive-Up Window Chime with Volume for Mier's Drive-Alert Systems

The DA-655 is ideal when a more pleasant tone is desired, instead of the whistle within the control panel of the DA-500 or DA-600. The DA-655 will be hardwired to the control panel of the DA-500 or DA-600, and emits a pleasant chime when a vehicle is detected. There is also a volume control, and this unit can be turned up to a high level.
The DA-655 works in a 9VDC to 30VDC range.
