3. Connect the wire with the eyelet terminals to the terminals of the batteries ([B]).
Attention:
Ensure that the polarity is correct.
Red - positive
Black - negative
4. Connect the battery wire connector to the connector on the power supply module ([C], paragraph 3.3 - [G]).
Connection of the batteries before the mains voltage is present will not activate the system. Once the mains voltage is
supplied, the power-supply module will connect the batteries automatically and initialize the circuits which manage
them.
5. The thermal probe must be positioned on the side of the battery and held in place by a strip of tape ([D]).
4.3.2Output connection
Each output of the IFM24160 module can be configured to activate specific conditions. If left at their default settings, the
three outputs will be as follows:
• OUT 1 (paragraph 3.3 - [D]), supervised output which activates in the event of a generic fire alarm
• OUT 2 (paragraph 3.3 - [E]), constantly active output (27.6V constant) for powering external devices
• RELAY (paragraph 3.3 - [F]), voltage free contact which activates in the event of fault
Each connection to these outputs ([E]) must be carried out in accordance with the instructions in paragraph 4.2.1.
Cables:
2-wire shielded cable
Proper section (minimum 0.5mm², maximum 2.5 mm²)
Compliant with local laws and regulations in force
Connection of polarized devices (sounders, etc.) to the OUT outputs
Refer to Figure 9 - OUT - a.
The polarities refer to the active status of the output, the polarities invert for stand-by status.
EN54:
If the control panel default settings are left unchanged, the OUT 1 output will result as being configured
as a type C output for the connection of audible/visual signalling devices.
The output will activate in the event of any type of fire-alarm condition.
Connection of non-polarized devices (relays, etc.) to the OUT outputs
Refer to Figure 10 - OUT - b.
The polarities refer to the active status of the output, the polarities invert for stand-by status.
Connection of a generic device to the RELAY output
Refer to Figure 11 - RELAY - a.
The OUT output illustrated in the diagram is used as a power source and is programmed as continuously active.
The illustrated connection does not supervise the cable and does not signal connection faults.
All voltage free relay contact can only be connected to SELV circuits.
EN54:
Refer to Figure 12 - RELAY - b.
If the control panel default settings are left unchanged, the RELAY output will result as being configured
as a fault signalling output.
In compliance with regulations the output will also result "inverted" in order to switch to fault condition
when the system is completely without power.
Therefore, in stand-by status (no faults present on the system) terminals C and NC will be closed,
whereas terminals C and NO will be open.
