The OKI FD-6612 is a fixed-temperature marine heat detector designed to trigger a fire alarm when ambient heat reaches 120°C. It is commonly deployed in shipboard fire detection and alarm systems where high operating temperatures make lower-threshold or smoke detectors prone to false alarms.
Key Capabilities & Design
- Fixed-Temperature Threshold: Triggers an alarm specifically when the surrounding temperature hits 120°C, making it suitable for engine rooms, galleys, and machinery spaces.
- Rapid Startup & Relay Output: Features a 10-second startup time and integrates an alarm relay output for direct connection to shipboard fire alarm control panels.
- Marine-Grade Durability: Built by Nippon Hakuyo Electronics with rugged ABS housing designed for anti-vibration, shock resistance, and moisture protection in harsh maritime environments.
