When the cable between the control panel and solenoid of cylinder connecting
with gas extinguishing control relay module is in short or open circuit, it reports
common fault and output fault; and
Common Fault
and
Output Fault
LEDs are lit.
When the cable between the control panel and pressure switch is in short or open
circuit, it reports common fault; and
Common Fault
LED is lit.
When the cable between the control panel and emergency start/stop button is in
short or open circuit, it reports common fault; and
Common Fault
LED is lit.
When the cable between the control panel and gas extinguishing warning indicator
is in short or open circuit, it reports common fault; and
Common Fault
LED is lit.
When voltage of input power is lower than 20V, it reports common fault; and
Common Fault
LED is lit.
After the above fault is removed, the corresponding LED turns off and the
control panel resumes proper operation.
Note: If there is short or broken circuit between the control panel and gas stop
indicator, or open circuit with the door switch, the control panel will report the
fault to FACP, but will not light its own fault indicator. After the fault is cleared, it
reports the clearing message to the FACP.

8 Caution
(1) After installation and commissioning, the commission technician must
check all jumpers and key covers meeting the requirements to ensure
proper use.
(2) After commission, measure with a multimeter to ensure there is no voltage
before connecting with the circuit of solenoid. Illegal operation is prohibited!
(3) Before powering up, check and fix all cable problems, such as short circuit,
open circuit and incorrect connections etc.
(4) The control panel generates audible alarm sound during the delay time, after
delay start and after pressure switch action is detected until
it’s reset. It’s
considered abnormal if
Emergency Start
button is pressed within 10
