Minimum Invasive Fire Detection for Protection of Heritage

cowiFire detection systems in general are effective fire safety measures for heritage
buildings and museums. Still, we are faced with these challenges of detectors and
inherent cable installations:
• Irreversibly impair fabric or décor
• Renovation and maintenance incur irreversible damage to fabric or décor
• Aesthetically invasive measures in sensitive environments
• Detectors do not respond to fires as quickly as anticipated
• Excessive nuisance alarms: detectors disconnected, or downgraded response
• Cable installations increase risk of fire from lightning
• Application may be inappropriate in terms of cost, efficiency, obtrusiveness
A summary of technologies used for minimizing invasive detector installations has
been made in this publication written by Geir Jensen, COWI AS, Norway. Results are evaluated and recommendations given.
