The Codesec K4 is engineered for simplicity and reliability in fire detection. Supporting up to 32 conventional detectors (smoke or heat) per zone, it allows for a maximum of 128 devices across its 4-zone architecture. The panel is equipped with a comprehensive front-panel LED display that provides immediate status updates on fire alarms, fault conditions, and power supply health. To ensure system integrity, the K4 features supervised siren outputs and zone inputs that detect open or short circuit faults via end-of-line (EOL) resistors. Key Features ? 4 Conventional Zones: Supports up to 32 conventional detectors (smoke or heat) and manual call points per zone. ? Independent Sounder Outputs: Equipped with two supervised siren outputs to ensure audible alerts are delivered throughout the premises. ? User-Friendly Interface: Clear LED indicators for Fire, Fault, Test, and Disabled states per zone, allowing for rapid diagnostics. ? Auxiliary Relay Outputs: Includes integrated fire and fault relays for interfacing with external systems like elevator recall, ventilation fans, or central monitoring stations. ? Battery Management: Built-in intelligent charging circuit with deep discharge protection to ensure the system remains operational during power outages. ? Sturdy Construction: Housed in a durable, aesthetic metal or high-impact plastic enclosure (model dependent) with a lockable front door for security. Technical Specifications ?
