Detnov CAD-150-8 Eight Loop Expandable Addressable Fire Alarm Panel

An addressable panel operating on four loops that can be expanded to eight loops by adding two TBUD-150 loop cards. With 250 addresses per loop, a total of 2,000 devices are addressed; this structure allows expansion without replacing the panel in phased-growth facilities. 40 alarm and fault zones are indicated by LEDs, and 6,000 event logs are maintained.
