Connecting the 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
50/60 Hz) through a switching power supply, located
inside the case. The FC501-L Control panel provides
housing for two 12V, 7Ah or 12Ah maximum batteries;
the FC501-H Control panel can be connected to two
12V, 12Ah or 38Ah in an external metal box (see Figure
14) for power during Mains failure.
The non-volatile memory will hold the programmed data
at all times.
In the event of MAIN failure, the:
AMBER Power Supply LED will turn ON.
The Control panel will check 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 Low Battery LED will turn ON. If
this occurs, the Mains power must be restored before
the batteries empty, otherwise, the system will shut-
down.
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 No 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).
Work carefully through the following steps to connect
the Mains Supply.
1. Locate the backup batteries in the housing (see Fi
-
gure 2). Secure the batteries to the backplate of the
panel, using the cable ties, in the appropriate ope
-
ning.
2. Using the Jumper (supplied), connect the batteries
in series.
3. Observing the battery polarity, connect the battery
terminals to terminals -BAT+ on Main Board (wires
supplied).
4. FC501-L use 7 or 12Ah @ 12 V YUASA batteries;
FC501-H/FC501H-K use 12 or 38Ah @ 12 V
YUASA batteries or similar with case flame class
UL94-V2 (or higher).
5. Connect the switching power supply
BAQ35T24/BAQ60T24 with the ‘external power
supply (Main): connect the Earth wire to the [Q] ter
-
minal on the mains terminal block 48.
6. Connect the Neutral wire to terminal [N], and the
Live wire to terminal [L] on the terminal board 48.
7. Connect the BAQ connector 50 to the main Board
connector 16.
+
The Control panel will reset on power up.
!
DO NOT allow the power cable to cross over ot
-
her wiring (see Figure 2). The power cable must
be routed and held firmly in place by a two ca
-
ble tie.

Thermal Probe
This Control panel supports the KST thermal probe.
The probe will optimize the battery charging process by
regulating the charge voltage in accordance with the
battery temperature.
Work carefully through the following instructions (refer
to the figure 13:
1. Connect the probe 54 to the connector 45 on the
BAQ35T24/BAQ60T24 switching Power supply.
2. Attach the probe to one of the batteries, in such a
way as to obtain optimum heat transfer.
3. Measure the Probe temperature.
4. Using the graph in Figure 12 and/or Table 7, find
the value (in accordance with the battery tempera-
ture) that the output voltage of the Switching Power
Supply will be based on.
5. Using the trimmer 46, adjust the voltage on the ter
-
minal board 47 to the required value.
+
To verify the battery efficiency, the charger circuit
will measure the internal resistance of the batte
-
ries. In order for this measure is not distorted, you
should use only the cables supplied; cables that
are longer and/or have an insufficient section may
erroneously simulate the condition of an inefficient
battery.
