Figure 5 Sample Trouble Message
If all troubles clear and no supervisory or fire conditions exist, the control panel does
the following:
• Returns to Normal mode;
• Sends an “All Systems Normal” message to the LCD display, the history file, an
optional LCD-80, an optional printer; and
• Restores troubles automatically even if troubles are not acknowledged.
Pressing <Alarm Silence> when only troubles exist, gives the same result as pressing
<Acknowledge/Step>. The Alarm Silenced LED does not light unless an alarm exists
in the system.
If multiple trouble conditions exist in the system, the LCD and optional LCD-80
displays automatically step through each trouble event every 3 seconds in the following
order:
1. Alarms, in order of address;
2. Supervisory, in order of address; or
3. Troubles, in order of address.
Press <Acknowledge/Step> and the display stops on the current trouble event for
1 minute. Press <Acknowledge/Step> to continue.
Fire Alarm
The system goes into Fire Alarm mode when the control panel detects a fire alarm.
During Fire Alarm mode, the control panel does the following:
• Produces a steady audible tone;
• Activates the System Alarm relay (MPS-400, TB3) and flashes the System Alarm
LED;
• Displays Alarm in the status banner on the LCD display;
• Latches alarms so they cannot clear until the alarm initiating device returns to its
normal condition and the operator resets the control panel;
• Initiates any Control-by-Event actions;
• Starts timers (such as Silence Inhibit, Auto Silence); and
• Activates the general alarm zone (Z00).
