Codesec DK231 Conventional Heat Detector

The Codesec DK231 is an open-area conventional thermal heat detector designed for commercial, residential, and industrial applications where optical smoke detectors are unsuitable, such as kitchens, boiler rooms, dusty workshops, and laundries. Operating on combined A1R principles (rate-of-rise thermal detection plus a 60°C fixed static heat limit), the onboard microprocessor continuously evaluates ambient temperature changes to ensure fast response during rapid temperature spikes. It operates across a 9V to 30V DC supply range, features twin red LEDs offering 360-degree visibility, supports connection to parallel indicators, and mounts on standard Codesec 2-wire conventional bases.
