Regular maintenance and reliability are key factors when choosing a smoke detector, and the Hochiki SLR-24H photoelectric smoke detector is designed to meet these requirements. This detector can be used in all areas where photoelectric smoke detection is necessary and is well-suited for fires ranging from smoldering to flaming types due to its wide range smoke chamber. It is compatible with a variety of bases such as the NS-4 Series, NS-6 Series, HSC-4R, and HSC-xxx R, allowing for easy integration with other Hochiki devices like the SIJ-24 ionization detector and the SLR-24V photoelectric detector. The SLR-24H features a low profile design at 2.2 inches high, making it suitable for spaces with limited ceiling height. It includes a 135°F fixed temperature heat sensor and is equipped with RF/Transient protection to ensure stable operation. The detector has built-in power/sensitivity supervision/alarm LED indicators and a vandal-resistant security locking feature. Additionally, it supports automatic sensitivity window verification, meeting the NFPA 72 requirements for inspection, testing, and maintenance.

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.
