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\u2014rather than point-by-point like other systems\u2014the 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\u2014not 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":"

Meusburger, a standard parts manufacturer based in Vorarlberg, recently invested in a large-scale photovoltaic system on the roof of its facility in Wolfurt. Siemens equipped the solar power plant with the FibroLaser early-fire-detection system, which detects sudden temperature differences in a linear manner and thus reports fires more quickly and with greater spatial accuracy than previous point-based systems.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":true,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":"","footnotes":""},"categories":[169],"tags":[162,170],"class_list":["post-10745","post","type-post","status-publish","format-standard","hentry","category-fruehling-sommer-2026","tag-digitale-transformation","tag-forschung-entwicklung"],"acf":{"meta_description":""},"author_meta":{"display_name":"magazineadmin","author_link":"https:\/\/partnerinfo.siemens.at\/en\/author\/magazineadmin\/"},"featured_img":null,"coauthors":[],"tax_additional":{"categories":{"linked":["Fr\u00fchling \/ Sommer 2026<\/a>"],"unlinked":["Fr\u00fchling \/ Sommer 2026<\/span>"]},"tags":{"linked":["Digitale Transformation<\/a>","Forschung & Entwicklung<\/a>"],"unlinked":["Digitale Transformation<\/span>","Forschung & Entwicklung<\/span>"]}},"comment_count":0,"relative_dates":{"created":"Posted 6 hours ago","modified":"Updated 3 hours ago"},"absolute_dates":{"created":"Posted on 30\/06\/2026","modified":"Updated on 30\/06\/2026"},"absolute_dates_time":{"created":"Posted on 30\/06\/2026 13:11","modified":"Updated on 30\/06\/2026 16:49"},"featured_img_caption":"","series_order":"","_links":{"self":[{"href":"https:\/\/partnerinfo.siemens.at\/en\/wp-json\/wp\/v2\/posts\/10745","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/partnerinfo.siemens.at\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/partnerinfo.siemens.at\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/partnerinfo.siemens.at\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/partnerinfo.siemens.at\/en\/wp-json\/wp\/v2\/comments?post=10745"}],"version-history":[{"count":0,"href":"https:\/\/partnerinfo.siemens.at\/en\/wp-json\/wp\/v2\/posts\/10745\/revisions"}],"wp:attachment":[{"href":"https:\/\/partnerinfo.siemens.at\/en\/wp-json\/wp\/v2\/media?parent=10745"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/partnerinfo.siemens.at\/en\/wp-json\/wp\/v2\/categories?post=10745"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/partnerinfo.siemens.at\/en\/wp-json\/wp\/v2\/tags?post=10745"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
