The Apollo Sounder Control Unit with Isolator (55000-852APO) is a specialized interface designed to manage a circuit of conventional notification devices within an addressable fire alarm loop. It allows for the centralized control of external sounders and beacons, providing a bridge between addressable intelligence and conventional alarm hardware.Notification Management: Enables the fire alarm control panel to trigger and monitor a complete circuit of conventional sounders as a single address, allowing for synchronized evacuation signaling across specific zones.Integrated Isolation: Features a built-in short-circuit isolator that protects the addressable loop. If a fault occurs on the sounder circuit or the loop itself, the unit isolates the problem area to maintain system-wide integrity.Supervised Circuitry: Continuously monitors the wiring of the conventional sounder circuit for open or short-circuit faults, reporting any issues back to the panel to ensure compliance with life-safety monitoring standards.External Power Support: Designed to be powered by an external 24V DC supply, ensuring that the sounder circuit has sufficient current to drive multiple high-output notification devices without overloading the loop.This control unit is the professional choice for upgrading legacy systems or for installations where high-current notification is required. It provides contractors with a robust, reliable method for integrating standard sounders into a modern XP95 or Discovery loop while ensuring full fault-monitoring capabilities.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.
