o protect from the threat of fire, sprinkler system design and manufacture is governed by strict standards. Though these
regulations are highly robust, some sprinkler system manufacturers say that standards can be extended further. “Key aspects of protecting a sprinkler
system’s backup and maintenance, for example, are not completely included in the regulations, but ensuring the long-term electrical reliability of the system is important to optimise safety,” says Gary Noble, managing director of Grifen Sprinkler Solutions. Features like Asset Protect are the result of
Grifen’s holistic focus on fire safety. The company supplies sprinkler system contractors in the UK and Ireland, with systems designed for domestic, industrial, and commercial buildings. Even Grifen’s sprinkler
systems for individual residences are electronically controlled by an industrial PLC, with logic control and software functions authored in-house. At the other end of the scale, its fire sprinkler systems for Category 4 commercial properties include remotely controlled testing on a weekly basis.
protection. So, Grifen uses Spelsberg’s high- durability industrial enclosures, manufactured from polycarbonate. These boxes protect in temperatures up to 80˚C, sufficient to match the rating of the electronics, and they endure until the sprinklers activate to quell the heat. The enclosures can also withstand water jets and provide a high IK09 impact resistance rating. To accommodate the automated system’s
multiple cable connections, as well as the control unit’s digital display, every enclosure requires a CNC machining process. The digital display window, as well as the cable entry points, must be cut in specified locations and to exacting dimensions. Crucially, when the display and the cables are installed, the surrounding gap must be sealed to uphold the level of ingress protection.
HigH durability enclosures Spelsberg provides all CNC work on-site at its Midlands facility, and although Grifen supplies its own drawings, Spelsberg’s technicians can also create CAD designs. Providing a test prototype in days, Spelsberg then despatched the full quantity of
Grifen’s order in less than three weeks. As a result of the enclosure’s precision CNC machining, combined with specially designed cable glands, when Grifen installed the control unit this upheld the high IP rating. Spelsberg also provides Grifen with digital
printing directly onto the enclosure, providing a highly durable, long-lasting finish. While the capability of Grifen’s systems lay
within its software functions, supported by the quality of flow control hardware, the protection of the automated system is fundamental. “We’re committed to Spelsberg for our
enclosures,” commented Noble. “We’ve put our faith in this process, and the quality of the service means there’s no going back.”
