HIGH FLOW ON
In case of simultaneous alerts/faults on the same LED, priority order is: ON (Highest), 1 blink, 2 blinks, 3 blinks (Lowest)
Note: The channel alarm and smoke level LEDs are under the
control of the CIE (Fire Panel).
Front Panel Buttons
The front panel has 3 user buttons: TEST, RESET and DISABLE.
These buttons are used to enter the pass-code which then allows
the user to carry out simple test functions.
Note: In Remote Maintenance and Service Mode, these buttons
are always disabled.
