The method comprises: detecting activation of one or more parts of the target operating device with a sensor of a wireless latching unit; latching a switch of the wireless latching unit from an active state to an inactive state upon detecting the activation of the one or more parts; transmitting one or more active signals from the wireless latching unit to abuse station upon latching the switch to the active state; detecting deactivation of the one or more parts of the target operating device with the sensor of the wireless latching unit; ignoring the detected deactivation at the wireless latching unit; and continuing to transmit the one or more active signals from the wireless latching unit to the base station. A wireless monitoring and control system is also disclosed.
