Supervisory Signal
Note: You can program
Supervisory signals as Tracking
or Latching.
Supervisory signals cause the control panel to do the following:
• Produce a warbling audible tone;
• Turn on the Supervisory relay (MPS-400, TB5) and flash the Supervisory LED;
• Display “Active” in the status banner on the control panel; and
• Turn off the panel sounder for all Silenced alarms.

Non-Alarm Point Operation
Non-Alarm points are MMX addressable modules that activate Control-by-Event.
These points do not activate the System Alarm LED or the panel sounder. Non-Alarm
points use three type codes: Non-Fire, Hazard Alert, and Fire Control.
Table 3 Non-Alarm Points
Trouble Monitor Point Operation
Trouble Monitor-type MMX modules monitor remote power supplies or other external
equipment. These types of MMX modules operate like troubles—but with the
following differences:
• The LCD display status banner displays “Active”;
• The type code is “Trouble Mon”;
• The modules latch—until the troubles are returned to normal condition and an
operator resets the control panel; and
• MMX modules can have Control-by-Event.
