Hold Condition
If any Extinguishant Hold Off button is pressed and held in a Flood Zone that is in a Fire Alarm condition,
and the Release Imminent countdown has started, the Release Imminent countdown for that Flood
Zone is held for as long as the button is pressed.
The display shows the
COUNTDOWN ON HOLD
condition and the
Timer Held
LED is illuminated.
When the HOLD button is released, the Release Imminent countdown is reset to the beginning and
restarts.
Abort Condition
If an Extinguishant Abort button is activated; in a Flood Zone that is in a Fire Alarm condition, the
Release Imminent countdown for that Flood Zone is aborted.
The display prompts for the panel to be reset and the
Aborted
LED is illuminated.
Ensure that the Extinguishant Abort button is de-activated and then press the
Reset System
button.
Note:
In accordance with EN 12094-1; it is a requirement that for a Dual Flood Zone panel, a common
output is needed to provide an indication of HOLD and ABORT activation from either flood zone. Refer
to Configuring the System, Set Common Output for HOLD & ABORT.
Fault Condition
If the panel detects a fault condition, the display will indicate the number and nature of the fault(s). The
internal buzzer will sound with an intermittent tone and the
General Fault
LED, and any other specific
Fault LED indications, will be illuminated.
Press the Up/Down arrow keys to scroll through the list of faults.
Press the
Mute Buzzer
button to silence the internal buzzer.
Note:
The fault condition is non-latching (except System Fault) and the indications will automatically
be cleared when the fault is remedied. Press the
Reset System
button to clear a System Fault.
Note:
If silenced, the buzzer will re-sound when a new fault occurs.
If a fault is detected in the second stage sounder circuit, the release countdown timer is halted and
extinguishant release is aborted. This is to prevent extinguishant release if a sounder fault prevents
people from being alerted to evacuate the release zone.
