OPEN CIRCUIT IN MASTER
(Open Circuit in the KMAY master for conventional detectors)
Cause
There is a lack of continuity in the wires for the line of slaves from the KMAY to the end
of the line. The end-of-line is not mounted.
Solution
Check that the KMAY is correctly connected to the detectors and manual call points
which are connected to it. Check that the end-of-line 10uF-63V condenser is correctly
connected, and with the right polarity (see chapter 1.5.4.1). To operate correctly the
KMAY’s output voltage should be between 18V and 21V.
SHORT CIRCUIT IN MASTER
(Short Circuit in the KMAY master for conventional detectors)
Cause
There is a short circuit in the connections from the KMAY to the end of the line.
Solution
Check that the KMAY is correctly connected to the detectors and manual call points
which are connected to it. Check that the end-of-line 10uF-63V condenser is correctly
connected, and with the right polarity, and check that the slave manual call points are
connected with the correct polarity (see chapter 1.5.4.1). To operate correctly the
KMAY’s output voltage should be between 18V and 21V.
RELAY OPEN CIRCUIT 01
(Open circuit for the relay 1 of the MDA1Y, MDA2Y or MYOA)
Cause
There is a lack of continuity between the output of the relay 1 of the MDA1Y, MDA2Y or
MYOA and the end-of-line resistance.
Solution
Check that the MDA1Y, MDA2Y or MYOA is correctly connected to the sounders
connected to it, check that the 33 K
end-of-line resistance and the supervision diodes are
correctly mounted (see chapters 1.5.4.4, 1.5.4.5 and 1.5.4.3 voltage of the relay 1 of the
MDA1Y, MDA2Y or MYOA must be between -2 V and -7,8 V when in standby and
between 24 V and 29 V when activated.
RELAY SHORT CIRCUIT 01
(Short circuit for the relay 1 of MDA1Y, MDA2Y or MYOA)
Cause
There is a short circuit between the output of the relay 1 of the MDA1Y, MDA2Y or
MYOA and the end-of-line resistance.
Solution
Check that the MDA1Y or MDA2Y is correctly connected to the sounders connected to it,
check that the 33 K
end-of-line resistance and the supervision diodes are correctly
mounted (see chapters 1.5.4.4, 1.5.4.5 and 1.5.4.3). To operate correctly, the output
voltage of the relay 1 of the MDA1Y, MDA2Y or MYOA should be between -2 V and
-7,8 V in standby and 24 V to 29 V when activated.
RELAY OPEN CIRCUIT 02
(Open circuit for the relay 2 of the MDA2Y)
Cause
There is a lack of continuity between the output of the relay 1 of the MDA2Y and the end-
of-line resistance.
Solution
Check that the MDA2Y is correctly connected to the sounders connected to it, check that
the 33 K
end-of-line resistance and the supervision diodes are correctly mounted (see
chapter 1.5.4.5). Check the status of the fuse protecting the module. To operate correctly,
the output voltage of the relay 2 of the MDA2Y must be between -2 V and -7,8 V when in
standby and between 24 V and 29 V when activated.
RELAY SHORT CIRCUIT 02
(Short circuit for the relay 2 of the MDA2Y)
Cause
There is a short circuit between the output of the relay 2 of the MDA2Y and the end-of-
line resistance.
Solution
Check that the MDA2Y is correctly connected to the sounders connected to it, check that
the 33 K
end-of-line resistance and the supervision diodes are correctly mounted (see
chapter 1.5.4.5). To operate correctly, the output voltage of the relay 2 of the MDA2Y
must be between -2 V and -7,8 V when in standby and between 24 V and 29 V when
activated.
