Connecting a Power Supply
+
The power circuits of this Control panel comply
with the EN54-4 standard.
!
In order to comply with the Safety regulations
in force, the Mains must be equipped with a bi-
polar isolating device for protection against
over voltage and short-circuit to Earth (e.g. au-
tomatic isolating switch).
This Control panel is powered from the Mains
(230V/50 Hz) through a Switching power supply, loca-
ted inside the case. The J408 Control panel provides
housing for two 12 V, 7 Ah maximum batteries, where-
as, the J424 Control panel provides housing for two
12 V, 17 Ah maximum batteries for power during Mains
failure. The non-volatile memory will hold the program-
med data at all times.
In the event of Mains failure, the:
Ø GREEN Mains LED will turn OFF
Ø RED Mains LED will turn ON
The Control panel will monitor the batteries at all times,
(refer to Static Test and Dynamic Test ).
Static Test The Static Test monitors the battery char-
ge during Mains failure. In the event of Low battery sta-
tus (below 22.8 V), the Battery LED will turn ON. If this
occurs, the Mains power must be restored before the
batteries empty, otherwise, the system will shutdown.
Low battery restoral (over 24.6 V) will be signalled by
blinking on the Battery LED (Memory).
Dynamic Test The Dynamic Test monitors the opera-
ting capacity of the batteries. In the event of a Failed
Test result (batteries do not meet the Test require-
ments), The Battery LED will turn ON.
If this occurs, the backup battery must be replaced im-
mediately, otherwise, the system will be unable to fun-
ction in the event of Mains failure (black-out).
Battery trouble restoral will be signalled by blinking on
the Battery LED (Memory).

Connecting the Mains Supply
Work carefully through the following steps (refer to the
figures on pages 12, 14, 18 and 19).
1. Locate the backup batteries in the housing 20 .
2. Using the Jumper (supplied), connect the batteries
in series.
3. Observing the battery polarity, connect the battery
terminals to the wires 60 .
+
If you are connecting 17 Ah batteries, you must re-
place the wire 60 and jumper connectors.
+
J424: Use 17 Ah @ 12 V YUASA NP 17-12 FR bat-
teries;
J408: Use 7Ah @ 12 V YUASA NP7-12 FR batte-
ries; or similar with case flame class UL94-V2 (or
higher).
4. Connect the Earth wire to the [ Q ] terminal on the
terminal board 53 .
5. Connect the Neutral wire to terminal [N], and the
Line wire to terminal [L] on the terminal board 53 .

The Control panel will reset on power up.
