RELAY SHORT-CIRCUITED:01
(Short circuit for the S1 General Sounder relay)
Cause
There is a short circuit between the output of the S1 General Sounder relay and the end-
of-line resistance.
Solution
Check that S1 General Sounder output is correctly connected to the sounders connected to
it, check that the end-of-line resistance (4K7) and check the supervision diodes are
correctly mounted (see chapters 2.3.3.1 and 2.3.3.2). To operate correctly, the S1 General
Sounder’s output voltage must be between -10V and -18V when in standby and between
24V and 29V when activated.
RELAY OPEN CIRCUIT:03
(Open circuit for the S3 General Fault relay)
Cause
There is a lack of continuity between the output of the S3 General Fault relay and the end-
of-line resistance.
Solution
Check that the S3 General Fault output is correctly connected to the devices connected to
it, check that the end-of-line resistance (4K7) and the supervision diodes are correctly
mounted. Check the status of the S3 output fuse (1 Amp). To operate correctly, the S3
General Fault’s output voltage must be b10V and +18V when in standby and 0V
when activated.
RELAY SHORT CIRCUIT:03
(Short circuit for the S3 General Fault relay)
Cause
There is a short circuit between the output of the S3 General Fault relay and the end-of-
line resistance.
Solution
Check that the S3 General Fault output is correctly connected to the devices connected to
it, check that the end-of-line resistance (4K7) and the supervision diodes are correctly
mounted. To operate correctly, the S1 General Sounder’s output voltage must be between
+10V and +18V when in standby and 0V when activated.
4.4.3.- LOOP FAULTS
ELEMENT NOT RESPONDING
Cause
An element in the loop has stopped working.
Solution
Check that the element has not been removed from the installation, check that the element
is correctly connected and that the loop voltage reaching it is between 22V and 35V. Also
check that it has not been affected by external agents such as water leaks, etc.
If this fault affects several elements, check whether they are all between the same two
insulators. If this is the case, check that section of the installation, as there must be a short
circuit in the wiring.
EXCESSIVE POWER CONSUMPTION
Cause
The loop is overloaded or has a short circuit; the voltage in the loop is below 22V.
Solution
Check the wiring for the affected loop, check for possible short circuits, and check
whether there are elements connected to the loop that should not be directly connected to
it, such as: conventional detectors, end-of-line condensers or resistances, electromagnets,
sounders, etc. Also check that it has not been affected by external agents such as water
leaks, etc. Once the original cause of the fault has been located and resolved, wait 5
minutes before resetting the incident in the control panel, since the protection elements
need to cool down. For normal operation, the voltage in the loop should be between 22V
and 35V.
OPEN LOOP
Cause
The loop is not closed properly as a result of an open line or a short circuit.
Solution
Check wiring and connections of the affected loop.
