FIRE SAFETY
Category 4 commercial properties include remotely controlled testing on a weekly basis. This optimises safety by providing more regular tests than the regulations require and reduces the resources necessary for on-site inspection.
AUTOMATION ENHANCES SAFETY The system’s electronics need a high level of protection. In the event of a fire, the enclosure must be able to withstand the initial heat. Then, the unit has to prevent water ingress when the sprinkler system is activated. The enclosures also have to be sufficiently durable to protect the electronic controls from any impact. 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’s machining ensures repeatability,” says Noble. “It’s also a fast turnaround, so it’s become a key service for us.” Although Grifen’s control unit is designed to be accessed remotely, or via the digital display, the device is still required to present a variety of user and safety information. Spelsberg provides Grifen with digital printing directly onto the enclosure, providing a highly durable, long-lasting finish. Combined with Grifen’s graphic design, Spelsberg’s printing service also ensures a professional presentation.
TIME-SAVING SERVICE “Previously, we used stick-on labels. Printing directly onto the box is much more hardwearing, and it saves us significant time resource compared to manual application. It also ensures a high- quality finish,” says Noble. 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,” says Noble. “We’ve put our faith in this process, and the quality of the service means there’s no going back.”

FIRE ALARM CONTROL FOR MARINE VESSELS
J
ohnson Controls has launched the ZETTLER T1306 addressable marine fire alarm control panel. It is the first addressable, networkable alarm panel from Johnson Controls specifically developed for use within small-scale marine vessels. The control panel’s mild steel construction offers increased durability and a sleek appearance, while addressable technology helps make installation, configuration and commissioning easier than ever before. It is available for distribution in Europe, Middle East, Asia-Pacific and Africa. Addressable technology
allows mariners to quickly and clearly pinpoint fire locations, increase
response times and inform
muster protocols if necessary. A
24-hour battery capacity helps improve maximum operational uptime, and two external battery boxes keep panel dimensions sleek to fit in tight areas. Combined with advanced control panel technologies that have been proven to reduce false alarms and built-in fail-safe mechanisms, the small marine panel is designed to help increase safety for humans and assets onboard. The T1306 addressable marine fire alarm panel can accommodate both visual and audible alarms. It is equipped with two full-powered loops that can be split into six shared power loops to support up to 500 devices for maximum configuration flexibility. An intuitively designed LCD display and robust tactile response buttons and switches help to increase usability in harsh marine environments. The panel can be mounted within the bridge, or remotely coupled with an in-bridge repeater to conserve space within the command center. Additional key features include a top and bottom entry gland plate, communication via Modbus to gateway (SMS/MIS) and four-panel capacity in the master/client configuration. The T1306 fire alarm panel has an IP32 rating and has earned various global industry approvals, including EN54, MED, ABS, BV, DNV GL, KRS, LRS (IACS) and CCS.
