4.1.2. Connection Diagram of Main Power Supply Unit and Back-up Battery
The connection between the accumulator battery and the main power unit has some special features. It is strongly
recommended to use only battery with electrical characteristics and dimensions pointed from the manufacturer. Before
connecting to the main power unit check the polarity of the battery. The battery cannot power up the panel before the
mains supply has been switched on. Connect the battery after the mains supply is turned on. If the battery is new, it will
take a few hours before its complete charging!
The charging of the accumulator battery is done at maximum current I=2A and charging voltage U < 13.8V.
Main power
supply unit
•
Connect 230V AC power source to fuse terminal block as strictly observe the polarity.
•
Connect the red cable to the positive pole of the battery, and the black cable - to the negative battery pole. Both
of the cables are connected to the battery by means of a flat terminal lug Ø5mm or cable shoes.
•
Place the temperature sensor behind or under the accumulator battery to provide correct measurement the
battery temperature and calculation of the internal resistance value Ri.
4.2. Outputs Control Module
The Outputs Control module in iRIS4 addressable fire alarm panel is a structure of two PCBs mounted to each other via
interface slot: Monitored outputs PCB and Programmable Relays PCB.
ATTENTION: The Outputs Control Module could not work independently!

1 - Monitored Outputs PCB. The PCB is under the Relays
PCB. The elements are indicated with blue numbers.
2 - Jumper for enable/disable indication for earth fault (EFault).
For example, if you want to enable the earth fault indication set
a jumper.
3 - Monitored Outputs - see the detailed description below.
4 - LED (green) – Indication for data transfer between the main
microprocessor of the panel and the Output Module. In normal
operation mode it is constantly blinking.
5 - LED (red) - Indication for power supply at the terminal for
connection of the first Loop expander. In normal operation
mode it is constantly lighting on.
6 - Interface connector for connecting the first Loop Expander
Module (on the back side of the Outputs Module).
7 - Ribbon cable interface connector from the main power
suply unit and to the front panel (on the back side of the
Outputs Module).
8 - Relays PCB. The elements are indicated with black
numbers.
9 - Programmable volt free switching over relay contacts - see
the detailed description below.

Attention: Check the earth
connection cable before
switching on the mains power
supply – the connection must
be tight and stable to ensure
the correct operation of the
panel and accurate LED
indication on main power
source for possible problems
with earth connection of the
panel.
Before the mains supply is
switched on, check the
correct connection of each
loop, sounder or any other
input or output, and the earth
connection cable.
