Meusburger, a family-owned company, is the market leader in the manufacture of high-precision standard parts for customers in the tool, mold, and machine building industries. By installing a solar power system with a capacity of 1,275 kWp and 3,000 modules, the Vorarlberg-based company has now put the plant\u2019s energy supply in Wolfurt on a sustainable footing. Since the roof on which the modules were installed is not fire-retardant, a guideline required an additional system to detect fires early. \u201cThe primary fire hazards are faulty or loose plug connections, as well as so-called power optimizers, whose electronics can overheat,\u201d explains Simon Schreiber, Siemens sales manager in Vorarlberg. “However, it is highly unlikely that the PV modules themselves would catch fire.”<\/p>\n\n\n\n

With FibroLaser, an alarm is triggered early enough to allow a fire to be contained in a timely manner.<\/figcaption><\/figure>\n\n\n\n

Faster and more accurate than expected<\/strong><\/h4>\n\n\n\n

The system used was arguably the most advanced early-warning fire detection system currently available on the market. Schreiber: \u201cWe installed a linear heat detection system, the FibroLaser, at Meusburger.\u201d A special ring-shaped fiber-optic cable is laid beneath the modules and connected to a controller, which processes the data and is linked to the existing Siemens fire alarm system. The fiber-optic cable has an FRNC jacket (Flame Retardant Non-Corrosive, HM4) and is therefore UV-resistant, halogen-free, and flame-retardant.
, the operating temperature ranges from \u201325 to 85 \u00b0C. A particular advantage: Since the FibroLaser uses an optical fiber and therefore does not require copper cables, even lightning strikes do not cause the fire detection system to fail.<\/p>\n\n\n\n

“The FibroLaser continuously sends a laser beam into the fiber-optic cable,” explains the expert. If there is a significant rise in temperature within a predefined time frame, or if a specified maximum temperature is reached, the curvature of the optical fiber changes, and the system can pinpoint exactly where the event occurred. \u201cThe pre-alarm, which is triggered immediately, responds so quickly and pinpoints the location of the incident so precisely that, if necessary, even an employee with a hand-held fire extinguisher can arrive on the scene in time to contain the fire before it spreads over a large area,\u201d said Simon Schreiber. Otherwise, an alarm will be triggered and the fire department will be notified automatically. In addition to pre-alarms and alarms, malfunctions in the fire alarm control panel and the Sicontrol security control station from Meusburger are also displayed.<\/p>\n\n\n\n

Linear detection instead of point-by-point detection<\/strong><\/h4>\n\n\n\n

Since the optical fiber operates linearly – rather than point-by-point like other systems – the FibroLaser detects a fire extremely quickly and triggers the alarm early enough. Systems based on point-to-point detection cannot match this performance: If a fire breaks out, for example, exactly between two detectors, the fire may have already spread before it reaches a detector, which then triggers the alarm only after a significant delay. This is bound to cause massive damage to the PV system and the building. Schreiber: \u201cWe have invested a great deal of energy and our many years of experience in monitoring photovoltaic modules – not least in light of the wide temperature range across the different seasons, during which the system must detect rapid temperature increases.\u201d The result is a reliable early-warning fire detection system whose operational suitability, availability, and reliability have already been impressively demonstrated in several projects. And best of all: FibroLaser is suitable for new PV systems, but existing systems can, of course, be retrofitted with it as well.<\/p>\n","protected":false},"excerpt":{"rendered":"
