2.4. Multiple Events
Often, several types of events occur within a short span of time. When this happens, the system provides for priority of
events.
2.4.1. Event Priority
The AUTOCALL TFX-500M/800M control panel gives alarms priority over trouble conditions. If a trouble condition is
present in the system when a FIRE alarm is received, the system will respond as follows:
S
The yellow System TROUBLE LED will remain on, but Zonal TROUBLE LEDs will go out.
S
The system will respond to the alarm as described in “Quick Response ------ Fire Alarm”
(Section 1.1). Once the alarm has been cleared and the system reset (See “Quick
Response ------ System Reset,”Section 1.6), the system will again respond to the trouble.
If an alarm condition is present in the system when a trouble is received, the System
TROUBLE LED will go on, but the Zonal TROUBLE LEDs will not respond to the trouble
until the alarm has been cleared. If an alarm condition is present in the system when a
second alarm is received, the system response depends upon the nature and source of
the second alarm. This happens as follows:
1. If the bells, horns, strobes (signalling appliances) have NOT been silenced, the following will occur:
a. FIRE ZONE red light LED will begin blinking.
b. Internal buzzer will sound continuously.
c. Display shows the message for the FIRST alarm.
d. Outstanding Events counter on the display will be incremented (increased by one).
2. If the bells, horns, strobes (signalling appliances) HAVE been silenced and the new alarm is in the
SAME zone as the first alarm, the following will occur:
a. Outstanding Events counter will be incremented.
b. Signalling appliances will not be reactivated.
3. If the bells, horns, strobes (signalling appliances) HAVE been silenced and the new alarm is in a DIF-
FERENT zone as the first alarm, the following will occur:
a. FIRE ZONE red LED will begin to blink.
b. Internal buzzer will sound continuously.
c. Signalling appliances will be re-activated.
d. Outstanding Events counter will be incremented.
NOTE: If the second alarm is an EVACUATE alarm, the signalling
appliances and internal buzzer will be activated and the
appropriate FIRE ZONE LED will blink.

All indicating appliances resound EXCEPT the ones in the “Bell Map Alarm Sounders”Group (common alarm sounders) IF
the new Alarm is an Alert coming from a zone already in alarm . AUTOCALL TFX-500M/800M CONSYS

provides for an “Alarm Resound Always”option. If this option has been programmed, all bells, horns and other indicating
appliances will resound when ANY Alarm event occurs (in the same or different zone).
2.4.3. “Bell Map Alarm Visuals” Group
The “Bell Map Alarm Visuals”group function allows the “Bell Map Visuals”group to remain ON after other indicating
appliances have been SILENCED. This group is SILENCED only after
