correctly with the panel or
multiple devices on the loop
are not addressed. Check the

DEFAULT DATA
The fire panel resets to default
data
Unusable Base
The detector on the sounder
base is missing or not fitted
properly
Note:
You need access level L2 or L3
permissions to mute the Silenceable outputs
manually.
Disabled
This control panel can disable the devices on
the loop, SC2 output, OC1 and OC2 outputs, the
software zones, the RS485 network devices such as
the repeater, the client panel, and the FC500MFI.
DISABLED zones cannot generate alarms or
warnings of any kind, and DISABLED outputs cannot
be activated.
When the Disabled LED is on, this indicates the
Disabled status.
Note:
The Disable facility is available at access
level L2 or L3.
Reset
Resetting the control panel restores the outputs to
standby status, clears the memory, and disconnects
the power supply to terminal 24R for 2 seconds.
Note:
You need access level L2 or L3
permissions to reset the panel.
Interface
Visual signaling
The system status signals on the control panel LEDs
are as follows:
•
Green indicates that the power is ON.
•
Amber indicates specific operating modes,
for example Day or Night Mode, and Fault
conditions.
•
RED indicates alarm conditions.
Memory
The control panel indicates Fault events with a
blinking FAULT LED until the system resets, even if
the event clears before the reset.
Audible Signaling
The buzzer signals the control panel status as
shown in Table 3.
Note:
When the control panel mutes an alarm
and detects a new fault, the control panel
resounds the previous silenced alarm.
