4.2
Trouble Conditions
The system responds to other-than-normal conditions that are not caused by alarms by sounding the internal buzzer
and initiating a Trouble Condition.
4.2.1
Trouble Signals
If a device fails to respond, is disabled, the response is not within the normal parameters, or the system detects a fault,
the amber System Trouble or Fault LED will light. In addition, the amber Trouble LED in the Zone/Area section of the
panel will light to indicate the location, the panel’s internal buzzer will sound and the alphanumeric display will provide
detailed information.
4.2.2
Trouble Signal Response
To acknowledge a trouble signal, enter Control Level Two by pressing the [Shift] key, enable the control keys and press
the [Trouble Silence] key to mute the internal buzzer (under certain circumstances, the system may override the mute).
The amber Trouble Silenced LED will light to indicate that condition. The system will not allow a reset until the problem
is corrected. If necessary, the system allows disabling of individual devices and zones (see Section 4.5.3 “Enable/
Disable Functions”). After correcting the problem, press the [System Reset] key. The amber Trouble Silenced LED will
go out and the alphanumeric display will return to normal.
4.3
Alarm Conditions
The D8024 will signal an alarm if it detects an alarm condition or a fire drill test.
4.3.1
Alarm Signals
If the D8024 initiates an alarm condition, the red Alarm LEDs at the left of the LED display flash to indicate the system
has detected a fire condition and has activated its Notification Appliance Circuit (NAC) devices (horns, strobes, etc.),
the internal buzzer sounds, Zone/Area Alarm LED(s) light indicating the event location and the alphanumeric display
provides detailed information.
To test the alarm system, enter Control Level 2 by pressing the [Shift] key, enable the control keys and press the [Fire
Drill] key. The panel will activate all system NAC devices. The red Alarm LEDs at the left of the LED display will flash and
the internal buzzer will sound. The alphanumeric display will show a “Fire Test” message.
