Application Scenarios of Nonfir Sprinklers
The K5.6 special response sprinkler features precise temperature sensing and stable water discharge, tailored for moderate-risk areas requiring high fire control accuracy. Integrated into building fire protection systems, it responds accurately to fire signals, delivering targeted water mist to suppress early fires-ideal for intelligent buildings like offices and malls.
The K5.6 quick response sprinkler boasts fast thermal reaction, activating within seconds of fire detection.
