DEVICE FOR CONTROL AND DEMOLITION OF IGNITION CYLINDERS Russian patent published in 2013 - IPC G08B17/06 

FIELD: fire-prevention facilities.

SUBSTANCE: in the device of control and demolition of ignition cylinders comprising the power supply, switching units consisting of two key elements, the checking relays (switching of flow-around) and remote switches for each thread of ignition cylinders are mounted, in which each switching-on coil shunts threads of ignition cylinders, which switching-off coils are combined and are inputs for installation in the initial condition of a circuit of individual control of the ignition cylinders condition, the switching units through the current-limiting resistors are connected to the terminals of threads of ignition cylinders. The checking relay coils with the first terminals are connected to the process bus which is only used during ground testing, and with the second terminals they are connected to the input of the switching-on of flowing-around the device, the checking relay contacts are switched-on so that they form a circuit of series connection of threads of ignition cylinders and the current-limiting resistors. The input of each switching unit is connected to the onboard control system.

EFFECT: increased reliability due to galvanic isolation of monitoring circuits, which increases the level of security, the possibility of demolition of ignition cylinders one by one.
