1. A supervised fire suppression system comprising:
a) a discharge valve for controlling the release of a fire extinguishing agent from a container;
b) a control head operatively associated with the discharge valve for actuating the discharge valve in the event of a fie, wherein the control head may be disengaged from the discharge valve to facilitate inspection of the control head; and
c) an internal supervisory switching device mounted within the control head and configured to interact with the discharge valve to provide an indication when the control head has been disengaged from the discharge valve, wherein the supervisory switching device includes a micro switch that cooperates with an internal switch pin to provide an indication that the control head has been removed from the discharge valve, wherein the micro switch that cooperates with the internal switch pin is disposed within an adjoined housing adjacent to the control head, wherein a slidable wedge is positioned within the adjoined housing between the micro switch and the internal switch pin to facilitate indirect cooperation between the micro switch and the switch pin, wherein the slidable wedge is separate from the micro switch and the internal switch pin.
