The Apollo Zone Monitor with Short Circuit Isolator (55000-845APO) is a sophisticated interface designed to integrate a zone of conventional detectors onto an addressable fire alarm loop. This unit is the essential solution for system retrofits, allowing contractors to bring the intelligence of an addressable panel to existing conventional circuits without the need for a full rewiring project.Conventional Integration: Acts as a bridge between protocols, powering and monitoring a zone of up to 20 conventional detectors and reporting their status as a single address to the main control panel.Fault Protection: Features a built-in short-circuit isolator that monitors the addressable loop. In the event of a cable fault, it instantly isolates the affected section to ensure the rest of the fire system remains operational.Status Monitoring: Equipped with an intelligent LED indicator that provides clear visual feedback for “Normal,” “Fault,” and “Alarm” conditions, significantly speeding up on-site troubleshooting.Flexible Power: Can be powered directly from the loop for smaller zones or via an external 24V DC supply for larger conventional installations, providing the installer with maximum configuration flexibility.This zone monitor is the professional choice for building refurbishments where existing conventional infrastructure must be maintained and upgraded. It provides electricians and fire safety engineers with a reliable, cost-effective method for modernizing fire protection while maintaining strict compliance with circuit integrity standards.Explore the full Apollo range for compatible products and accessories.Why buy from Direct Trade Supplies?Competitive trade pricing, fast UK delivery, and trusted products from leading brands.
