Cerberus Pyrotronics LED-24 Annunciator Driver Circuit Board 30675

The Cerberus Pyrotronics LED-24 Annunciator Driver Circuit Board (part number 30675) is a specialized module designed for use in fire alarm and security systems, particularly within the MXL or similar control panels from Cerberus Pyrotronics (now part of Siemens). This board drives up to 24 LED indicators for zone annunciation, providing visual status updates for alarms, troubles, and supervisory signals. It features relay outputs for controlling external devices, integrated ICs for signal processing, and fuses for circuit protection. Key benefits include reliable performance in critical safety applications, easy integration into existing fire panels, and modular design for quick replacement. Drawbacks may include obsolescence due to the age of the technology (likely from the 1990s), potential compatibility issues with modern systems, and the need for specialized knowledge for installation. Applications span commercial buildings, industrial facilities, and healthcare environments where fire detection and annunciation are essential. Compared to similar products like those from Simplex or Notifier, it offers cost-effective legacy support but may lack advanced digital features found in newer models. The board appears in good used condition based on images, with no visible damage, and includes original packaging.
