Power Supply
!
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, in-
stalled outside the control panel and easily ac-
cessible, with minimum contact distance of 3
mm (e.g. automatic isolating switch).
The ABSOLUTA Plus is powered from the Mains
(230V/50 Hz) through a Switching power supply, lo-
cated inside the cabinet. The cabinet can also house a
backup battery (not included) for power backup during
Mains failure.
Mains failure will be signalled by the:
Ø
OFF status of indicator on the Power Supply;
Ø
ON status of the
G
indicator on Keypads;
Ø
Warning Mains failure
event.
+
The
Warning Mains failure
event will be signalled
after the programmed delay (refer to “Filter Times”
in the “PROGRAMMING FROM PC” section).
The panel reports a fault when the output voltage drops
below 11.2 V, with:
Ø
ON status of the
G
indicator on Keypads;
Ø
the message
Panel low Vout
on the LCD
Keypads, in
View Signals
mode.
The Control Panel will monitor the battery at all times,
(refer to
Static Test
and
Dynamic Test
).
Static Test
The
Static
Test monitors the battery
charge during Mains failure.
Low battery
status (below
11.4 V) will be signalled by the:
Ø
Low battery
event;
Ø
ON status of the
G
indicator on Keypads.
If this occurs, the Mains power must be restored before
the battery empties, otherwise, the system will shutdown.
Low battery restoral (over 12.3 V) will be signalled by:
Ø
the end of the
Warning low battery
event;
Ø
The
G
indicator on Keypad turn OFF only after the
reset of all events (the events stay in memory).
+
The Control Panel automatically shuts down when
the battery voltage drops below 9.6 V to protect the
battery from permanent damage.
Dynamic Test
The
Dynamic
Test monitors the oper-
ating capacity of the battery. A failed test (battery does
not meet the Test requirements) will be signalled by the:
Ø
Warning power trouble
event;
Ø
ON
status of the
G
indicator on Keypads.
If this occurs, the backup battery must be replaced im-
mediately, otherwise, the system will be unable to func-
tion in the event of Mains failure (black-out).
Battery trouble restoral
will be signalled by the:
Ø
end of the
Warning power trouble
event;
Ø
The
G
indicator on Keypad turn OFF only after the
reset of all events (the events stay in memory).
n
Power connection
Work carefully through the following steps (refer to
“Parts Identification”).
1.
Locate the backup battery on its housing
33
.
2.
Connect the backup battery to the connector
13
on
the Main Board, by means the cable
30
.
3.
Connect the
Earth
wire to the [
Q
] terminal on the
power supply terminal board.
4.
Connect the Neutral wire to terminal [N], and the
Line wire to terminal [L] on the power supply termi-
nal board.
As soon as the control panel is powered, you can pro-
ceed with the wizard setup using one of the keypads
connected to the control panel, as described in “Wizard
setup” on page 37.
If the keypads do not work, check the diagnostic LED
(see
21
Ø
LED off: the control panel board is not powered.
Ø
Flashing LED: the control panel board is powered
but no keypad is connected on the BPI bus, or the
connected one does not work, or its address is the
same as that of another keypad (address conflict on
the bus).
Ø
LED on steady: the control panel board is powered,
and has at least one keypad connected on the BPI
bus operating properly.
+
The Control Panel Tamper Switch is enabled by
the initial closure of the Control Panel. Therefore, it
cannot trigger a
Tamper on Panel
event on first
power up. Likewise, if the Panel is opened during a
programming session (via Keypad or computer),
the Tamper switch will be inhibited thus unable to
trigger a
Tamper on Panel
event until the Pro-
gramming session ends, and the Panel is closed
again.
