status remains until the Night Mode Silence time
expires.
At default, the system is set to Day Mode. During
Day Mode, silenced alarms are not unmuted
automatically.
Fault
This control panel can detect and signal the faults
shown in Table 2. Fault conditions signals are:
•
Control panel buzzer; 1 second of sound at
660 Hz and a 1 second pause.
•
The Fault LED and relative Fault LED is on.
•
A Fault message on the LCD display.
•
Activation of the Fault output.
•
Activation of other outputs including SC2, OC1
or OC2 if programmed.
The Fault output and any additional programmed
fault outputs automatically return to standby status
when the fault conditions clear.
Under certain circumstances, fault conditions may
clear spontaneously. If this occurs, the memory
stores the event until you reset the control panel.
Blinking on the Fault LED indicates stored fault
events.
Silence
This control panel provides a
Silence
key that can
restore the Silenceable outputs to Standby status.
When the Silence LED is on, this indicates the Silence
status.
The Silence status remains until one of the following
occurs:
•
You press the Silence key again
•
The programmed Night Mode Silence time
expires when the control panel operates in
Night Mode.
•
A new alarm condition is detected.
