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 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. 

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.

Non-fire
(Tracking)

Activates Control-by-Event only.

Energy management or other 
non-fire situations.

Hazard Alert  
(Latched)

Sends a message to the LCD display, 
history file, printer, and ADT-LCD-
80 (status – Active), and overrides 
code selection for NACs, regardless 
of the zone F8 coding selection. 

Monitoring critical processes or 
other hazardous situations, such 
as a tornado.

Fire Control
(Tracking)

Sends messages to the LCD, history 
file, printer and ADT-LCD-80.

Air handler shutdown,  intended 
to override automatic fire 
functions.
