1. A control system for silencing an alarm signal from an alarm device, the control system comprising
a sensor configured to receive an alarm signal from an alarm device;
an input interface configured to receive an operator instruction to silence the alarm signal; and
control logic configured to issue in response to the operator instruction a silencing instruction interpretable by the alarm device as an instruction to deactivate the alarm signal,
wherein the control logic is configured to receive the alarm signal from the sensor and the control logic is configured to determine whether or not the alarm signal exceeds a signal threshold indicative of the proximity of the input interface to the alarm device, and
wherein the control logic includes an interlock preventing the silencing instruction from being sent for the alarm device if the signal threshold is not exceeded.
