Installation and connection
The power supply unit must be installed firmly with a three-conductor cable, whose phase, neutral and protective earth conductor, (PE) must be connected according to the marking of the terminals. Transient protection is recommended. The mains voltage to the power supply unit must not be interrupted by the fire protection system
main switch. An external installation switch with a rated current of at least 3 A must be installed in the supply to the power supply unit. The supply and the switch must be marked red and provided with clear numbering. Each power supply unit must have its own separate switch.
The batteries must be connected last, after all other connections have been made (24 V outputs and indication circuits) and after connecting the
indicator diode wiring and possible tamper switch. Place the batteries in place on the floor of the cabinet and then place the temperature sensor in place
between the batteries so that it rests against both battery casings. Then connect the battery cables with the correct polarity: red to the positive pole (+) of one battery, black to the negative pole (–) of the other battery. Finally, connect the connection cable between the two batteries.

Notes
Each fault indication output has 3 relay contacts. The description of the relay connection reflects the conditions when mains voltage is switched off (relay coil de-energized).
The negative pole (–) of the external error input (8) is connected to the battery negative pole (B–). Fault indication is triggered if a short circuit (voltage 0 V) is detected. In this state, approximately 0.25 mA flows between the positive (+) and negative (–) terminals of the input.
If the unit is to be equipped with the tamper contact, connect the tamper contact to the sensor (tamper) on the factory-set jumper on the Z204.
The only user replaceable components are the fuses as per the table below. The replacement fuses must have the same tripping current and

Notes
Each fault indication output has 3 relay contacts. The description of the relay connection reflects the conditions when mains voltage is switched off (relay coil de-energized).
The negative terminal of the external fault input (–) is connected to the negative terminal of the battery (B–
). Fault indication is triggered if a short circuit (voltage 0 V) is detected. In this state, approximately 0.25 mA flows between the positive (+) and negative (–) terminals of the input. If the unit is to be equipped with the tamper contact, connect the tamper contact to the sensor (tamper) on the factory-set jumper on the Z202.
The only user replaceable components are the fuses as per the table below. The replacement fuses must have the same tripping current and tripping characteristic as the replaced fuses.
tripping characteristic as the replaced fuses.
First start
When the power supply is turned on and no errors are present, the status indications according to the Correct Start column in the table below should be displayed. If the indications deviate from this, there are incorrect connections or other errors - see the error descriptions in the appendix.
Before using the power supply unit, two more tests must be carried out.
Uninterruptible power supply test
Switch off the mains voltage with the installation switch. The power supply unit must switch to battery operation and maintain unchanged voltage on both of its outputs. The voltage at the outputs can be checked with a voltmeter.
If the mains voltage is interrupted by removing the mains fuse B201, the mains voltage interruption is only detected after 10 minutes. The fault relay GEN
FLT reacts with a 5 second delay.
Battery circuit monitoring test
Check that the power supply unit is connected to mains voltage, then break the battery circuit by disconnecting one of the battery cables. The battery circuit break is detected at the next test, (detection can take up to 10 minutes).

GEN FLT | General error | The move | Not drawn | Not drawn |
*) If the battery circuit remains disconnected for more than 12 minutes, the BAT indicator light turns solid.
During testing, verify that the GEN FLT fault indication is indeed transmitted correctly to the fire alarm panel.
Operation and maintenance
After installation, the power supply unit only requires regular reading of error indications.
Output voltages and indication levels are factory set.
Do not connect the battery negative pole (B–) with the negative poles of the outputs OUT1 (–) and OUT2 (–)*.
* • Do not connect the minus pole of the battery (B-) to the minus poles OUT1 and OUT2 (-) for each other 1.5 ÷ 5.5 A and
to the negative terminals OUT1 ... OUT5 (-) for version 7.5 ÷ 12 A
The battery pack is connected to the power supply unit only when mains voltage is present and when the battery voltage exceeds 21.6 V. In case of battery failure (the terminal voltage of an individual battery lower than 10 V), the battery is not detected. The alarm indicator light ALARM will flash rapidly when the voltage is between these limits, but the battery will not be connected.
In battery operation mode in case of mains failure, the batteries are automatically disconnected by the low voltage disconnect device (LVDD) when the batteries are discharged below 21 V. After LVDD disconnection, the power supply unit still draws a very small current for internal needs.
The batteries must therefore not be left in this state for any length of time, as they can then be discharged to such a low voltage that they will not be reconnected when the mains voltage returns.
If the power supply unit is to be disconnected from mains voltage for a long time, the batteries must be disconnected. Otherwise, deep discharge can occur, which shortens the life of the batteries.
Battery life shortens drastically with increasing temperature. Every 8 to 10 °C increase in temperature halves battery life.
CNBOP and VdS recommend battery replacement every 4 years of operation, regardless of the condition of the batteries.
The tests described in the section First start, (see page 11.), should be repeated once a year to verify the operation and condition of the power supply unit.

*1) Failure of the power supply unit/charger is detected no later than 10 minutes after the failure occurred (checking is done at the same time as the battery circuit resistance is measured).
*2) Measurement of the battery circuit resistance, including checking for battery circuit interruption and tripped battery fuse, takes place every 10 minutes. When excessive battery circuit resistance is detected three times in a row, the indicator lamp BAT lights up and the relay indicator GEN FLT is triggered. This monitoring function allows the system to be checked (eg for maintenance purposes) by temporarily disconnecting the battery circuit without triggering any fault indication, if the battery circuit is reconnected within 2 minutes.
*3) To test this alarm, the battery and battery fuse need to be disconnected and then a single measurement as step *2 describes needs to be made. This allows testing of function without generating a GNT FLT (if reconnection occurs within 2 minutes).
