Patent ID: 11285347

Abstract:
A fire suppression system includes a tank configured to contain fire suppressant agent, a cartridge configured to contain pressurized expellant gas, the cartridge including an electrically-conductive section, an actuator coupled to the tank and selectively coupled to the cartridge, and a cartridge monitoring system coupled to the actuator. The actuator is configured to selectively supply the pressurized expellant gas from the cartridge to the tank such that the fire suppressant agent is dispensed from the tank. The cartridge monitoring system includes (a) a first contact and a second contact configured to engage the electrically-conductive section of the cartridge when the cartridge is coupled to the actuator and (b) an electrical interpreter coupled to the first contact and the second contact and configured to determine if the electrically-conductive section of the cartridge is engaging the first contact and the second contact to form a closed circuit.
