FAULT FINDING PROCEDURE
Conduct fault-finding with the system off (door closed).
PLEASE NOTE: Remember to set dip-switch 8 to OFF on completion of the procedure.
STEP
Action
Test
Diagnosis
1.
Open the base cover and observe
the red LED
Is the LOW BAT LED on?
A sensor has a low battery; find the sensor with
the flashing LED
2.
Is the ALARM LED on and fixed?
Communication problems between the sensors
and the base. Find the sensor with the LED off or
flashing very faintly
3.
Set dip switch 8 to ON:
the ALARM LED initially comes on
Are the three OUT1, OUT2 and BAT
LOW LEDs off?
The system is operating normally. If the control
unit does not show that the edge input has been
closed, there is a connection problem (broken
wire)
4.
Observe the LED for a sensor
Is the LED on and fixed?
The sensor detects that the edge has been
activated; connection problem or faulty edge
5.
Operate the edge
Does the LED on the sensor come
on?
The sensor does not detect the status of the
edge; connection problem or faulty edge
6.
-
Does the control unit indicate the
edge input is closed?
Connection problems between the control unit
and the base (short circuit)
7.
Repeat steps 4, 5 and 6 for each
sensor
Are all sensors operating normally?
A non-existent sensor is included in the network.
It is necessary to delete the network and repeat
assignment of the sensors
