In maritime environments, smoke detection is crucial for ensuring the safety of crew and passengers, especially in large spaces like ship atriums or industrial areas where conventional smoke detectors might not be as effective. The Hochiki SPC-24 smoke detector is designed to address these challenges by providing projected beam smoke detection that can cover wide areas up to 328 feet in range. This detector consists of an emitter and a receiver, each with distinct color-coded labels for easy identification. The microprocessor-based system ensures reliable operation and simplifies setup and alignment through visual signal strength LEDs. It offers three adjustable sensitivity settings and automatic compensation for signal drift or dirty lenses, enhancing its reliability in various environmental conditions. Additionally, the SPC-24 features voltage and RF transient protection and can detect smoke with a range of 25%, 50%, or 70% obscuration per span, making it suitable for high-risk areas such as factories, tunnels, and warehouses.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
