Systems and methods for testing an Arm and Fire Device (AFD). The system includes an AFD arm controller and a first power supply coupled to the AFD controller to provide arming power to the AFD controller. The system further includes a monitoring module coupled to the AFD controller through a plurality of means of isolation and communication. The monitoring module may include one or more monitor circuits for the AFD to test at least one circuit in the AFD, at least one circuit external to the AFD, or combination. The system further includes at least one output for the AFD to provide data from the monitoring module. The system may further include a first switch to control the monitoring module is powered and a second switch to control power to the AFD arm module. The system can include an input for applying data to the AFD.
