IFC-3030 Operations Manual — PN 52026:C 08/05/2005 23
2.2 Fire Alarm Event
2.2.1 How the Control Panel Indicates a Fire Alarm
When an initiating device (detector or monitor module) activates, the control panel does the
following:
• Produces a steady audible tone (if the piezo is enabled)
• Activates the System Alarm relay (TB4). It will also activate the Security (TB1) and
Supervisory (TB2) relays if their switches have been configured for alarm
• Flashes the
FIRE ALARM LED
•Displays
FIRE ALARM in the upper left corner of the display, a Type Code that indicates the type
of device that activated the fire alarm, and other information specific to the device. The
message occupies the top four lines of the screen, replacing the System Normal message as
shown in Figure 2.2 below. Refer to “Point Events Format” on page 13 for a full description of
each message field
• Sends an Alarm message to the History buffer and installed printer and annunciators
• Latches the control panel in alarm. (You cannot return the control panel to normal operation
until you correct the alarm condition and reset the control panel)
• Initiates any Control-By-Event actions
• Starts timers (such as Silence Inhibit, Auto Silence)
• Activates the general alarm zone (Z000)
Note: If a monitor module programmed with a
WATERFLOW Type Code initiates a fire alarm, the
control panel disables the
SIGNAL SILENCE key and the Auto Silence Timer.
