Baywear Clothing is a private company that has been operating in Port Elizabether/Gqeberha since 1952. The modern 2850m2 facebrick factory houses a vertical operation. Fabrics are knitted on a range of 80 body width machines using locally and internationally sourced yarns, primarily cotton, but also pure wool and other fibres.
Due to the nature of the factory, it’s understandable why a quality fire detection system is required. JZL Projects and Solutions were asked to provide a comprehensive yet cost-effective solution that would be installed with minimum disruption to the factory. Due to the expanse of the factory floors, optical beam detectors were the best choice for large coverage areas and as the fire alarm system would also be needed to control fire doors and shut down fresh air intakes, it required an addressable system.
JZL Projects and Solutions selected the EA-P116 1 loop addressable fire control panel along with The Fire Beam Blue optical beams, which could be powered from the loop of the EA-P116, simplifying the installation. This design was conceived following the White Paper from G2 Fire regarding how to correctly implement powering beams directly from the G2 addressable panels loop. This provided, not only a simplified installation, where additional 24Vdc power supplies are not required, but additionally leverages the inherent redundancy in the loop.
The key advantages of using the G2 addressable system, enabling the loop powering of the beams are:
- * Less points of failure
- * Reduction of service replaceable items (ie less batteries)
- * Faster & simpler installation
- * Reduced hardware costs
- * Easier to maintain
- * Simple programming
An additional 70 loop devices including addressable detectors, manual callpoints, sounders and I/O units were also attached to the single loop, to provide a holistic fire detection solution throughout the building.
