The Zonal Bell Monitor Board (ZMB24V) allows independent activation of one or more supervised bell circuits, for either evacuation or alert tones.
Single-way and four-way bell driver boards are available. Other combinations may be constructed by connecting the externally accessible bussed control signals.
