ACTION (red)
When the Action Threshold has been reached and the appropriate
time delays have expired. The detector will generate Action Alarm.
FIRE 1 (red)
When the Fire 1 Threshold has been reached and the appropriate
time delays have expired. The detector will generate Fire 1 Alarm.
FIRE 2 (red)
When the Fire 2 Threshold has been reached and the appropriate
time delays have expired. The detector will generate Fire 2 Alarm.
DET’N (yellow)
Smoke detection fault
FLOW (yellow)
Airflow Hi/Lo fault, air flow sensor fail, aspirator fail
SYSTEM (yellow) Except DET’N/FLOW error, all other error is SYSTEM error
AUX (yellow)
Any one of the GPI points on terminal board is in action
Bargraph
(yellow)
Display the real-time smoke level, with full scale of Fire 1 Level
In program mode, individual bargraph LED flashing indicates current
parameter no.
Note: The status of the alarm and fault LEDs might not represent current device status. This
is because the alarm/fault output will be maintained even when the alarm/fault condition no
longer exist if the Alarm Latch or Fault Latch function is enabled. A manual reset will be
needed to clear the alarm or fault.
o
6-digits Numerical LED
In normal operation, the 6-digit numerical LED displays real-time smoke level, airflow level,
device address and current event in occurrence. Press
v
w
buttons on panel could switch
the display item in sequence as follows:
Smoke(S)
D
Flow(F)
D
Address (Addr)

Auxiliary (Aux)
The 4 indication LEDs above the numerical display indicates which item is displayed. Press
w
key to switch rightward; press
v
key to switch leftward.
When switching to Aux, the total number of active events will be displayed first. Press
<+>
、
<-> key will show the detail event message, including date, time and event code. For
example, if there are two events: code A0 and E11 exist, it displays 2 when switching to Aux;
press <+> will display A0 event message, press <+> again will display E11 event message, and
then press <+> to return to the beginning 2. Where, 2 represented total events, A0 is the
