“Engineer-on-site” Mode
When in this mode, the MesCom will monitor all inputs and allow outputs to be changed but
will not generate notifications or trigger calls to the host. This mode should be used when
any work is being performed on the system.
“Engineer on site” input can be configured to any input - see section 7.7.22.
By default “Engineer on site” mode is entered holding the test button for longer than 10
second and exiting by holding the test button for 5-10 seconds.
