1. 7 joe j EO 5 In the event of fire the detector hose bursts When the pressure drop in the detection system has fallen to approx 10 bar a valve on the extinguisher cylinder is activated and the system is released The pressure switch on the detector cylinder sends an alarm to the driver position With a semiautomatic system depending on the version that has been installed either the vehicle contact key shall be turned off or the handbrake pulled on or the ladder lowered in order that the extinguishing shall be activated in the event of a fire The activation is delayed until this point with the help of a magnetic valve connected to the detector hose and this maintains the detector pressure to the extinguisher cylinder Note the vehicle manufacturer s appendix for information about the activation that is used On delivery of the system the detector cylinder shows approx 20 24 bar and is filled with detector fluid and a propellant The propellant consists of nitrogen gas The pressure can be read off on a manometer and shall be within the green sector If the pressure falls below 14bar which means too low a system pressure the pressure Fogmaker International AB 4 8016 002 switch sends an alarm the same alarm as with a fire As an option there is a detector cylinder with an extra pressure switch that sends an alarm if the pressure falls below 7 bar which means that the system is released with a fire The detector cylinder h2.
