8 : Command module detector
(1) The <TEST> Button starts a lamp test which makes the detector show its nominal operating
sensitivity as calculated by the ClassiFire Artificial Intelligence System.
(2) The <RESET> Button clears any latched alarms or faults and sets the status display back to
its normal operation display. To comply with national standards, detectors are supplied with
the RESET function disabled as the default.
(3) MENU Buttons are used when programming the unit, which is password-protected. See
“Navigating through the menus” on page 46, for more information. Pressing the UP or
DOWN arrow keys when not in Programming Mode (the access code has not been entered)
scrolls through the detector’s event log. Refer to “Event log” on page 61 for more information
(4) The OK Indicator illuminates to show normal operation when there are no faults. On the
command module, this means that the command module and all detectors on the loop are
operating normally.
(5) The Fault Indicator illuminates when the unit has a fault and a fault signal is being sent to
the fire alarm panel. On the command module, this also indicates a fault in a detector on the
communications loop, or in the loop itself.
