ABSTRACT:
An apparatus or system for detecting and extinguishing a fire originating in a fusing device or the like within a copying machine; means are provided for detecting the ionization of ambient air due to the existence of a flame within the fusing device, the ionization causing a substantial increase in the conduction of energy between a pair of flame detecting electrodes; the consequence is that the increased current causes an alarm to be given and/or automatically actuates a valve for ejecting a coolant or extinguishing chemical on the fire.
