1. A method comprising:
receiving a first burn signal at an interface of a first radio module of two or more radio modules of a latching mechanism;
receiving a second burn signal at a second interface of a second radio module of the two or more radio modules of the latching mechanism in response to a problem associated with the first burn signal;
toggling, via the second interface, at least one backup battery to pass current from the at least one backup battery to a conducting burn wire attached to the second radio module, wherein the conducting burn wire is attached to a portion of a string; and
melting, by the conducting burn wire, the portion of the string, wherein the string is connected between a first panel and a second panel.
