light sound and sounding of building fire alarm the magnetic field protection shield 38 located adjacent to the interior wall of enclosure 1 provides adequate protection of data loss due to high intensity magnetic fields present outside the enclosure 1 an enclosure temperature sensor 32 located within the enclosure 1 allows the internal control unit 30 to turn on a fan 36 in the event of needed cooling to protect the various components once the enclosure is safely closed the external control unit 120 provides an indication of such event through the status indicator 140 located on the shroud door 7 during a hard shutdown inputs from the various adverse external condition sensors such as smoke sensor 122 vibration sensor 124 light sensor 126 sound sensor 128 water sensor 130 temperature sensor 132 and magnetic field sensor 134 provides a signal to the external control unit 120 of an event such as fire heat water moisture magnetic fields static electricity vibration motion theft tampering unauthorized use dust power interruption light sound and sounding of building fire alarm upon receipt of such signal the external control unit 120 sends a signal to the internal control unit 30 the events that follow parallel the soft shutdown sequence the internal control unit 30 sends a signal to both the electromechanical disconnect assembly 12 and the door actuator assembly 16 the electromechanical disconnect assembly 12 disconnects enclosure electrical connector interface 11 from the external control unit connector interface 10.
