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, TB4) 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 M500M 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 M500M modules monitor remote power supplies or other
external equipment. These types of M500M 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
•M500M modules can have Control-by-Event.
