Installation and Programming manual

1.2 The system parts and definitions

Power supply module: a module, connected to the mains 230 Vac, which supplies a stabilized voltage @

24 V (27.6 V) to the system and the charge source to the batteries. The power-supply module is located
below the mother board and is EN54-4 compliant. The mains voltage (230 Vac) is the primary power
source of the system. See also paragraph 7.5 Connecting the Mains.

Batteries: the secondary power source of the system. The power supply station enclosure houses two lead
batteries @ 12V 7Ah (depending on the model) connected in series. The system monitors the battery
status (efficiency and charge). A fault signal will be generated when voltage overload/underload or
inefficient battery conditions occur (Appendix A2). In the event of primary power (230 Vac) failure, the
batteries will take over, however, they will shutdown automatically if the blackout persists. The automatic
battery shutdown feature prevents irreparable damage to the batteries. See also paragraph 7.6 Connecting
the batteries.

Thermal probe: an accessory tool connected to the panel and attached to the battery pack. This device
monitors the temperature of the battery pack and regulates the battery charge accordingly. See also
paragraph 7.7 The thermal probe.

RS485 BUS: 4 wire BUS which allows the power supply station to be connected directly to INIM fire
detection panels (SmartLoop, SmartLight and SmartLine). Four pole shielded-twisted cable must be used
for all connections. See also paragraph 7.2 RS485 BUS wiring.

Chapter 4

Functions and features

4.1 Controlling the Outputs

The power-supply outputs can be controlled locally, via the on-board inputs B1, B2 and B3 or remotely, via
the RS485 BUS of an INIM Fire detection panel.

The outputs follow the "OR" logic of the status of their command inputs, refer to the following Table.

You can define the standby status of each output using the Booster option in the programming menu (refer
to paragraph 10.1.1 Setting up the Booster parameters):

1. Standby-ON

Under these circumstances, there will be 24V (ON) across the terminal when the output is in standby
status and 0V (OFF) when the output activates. This is the setting at default.

2. Standby-OFF

Under these circumstances, there will be 0V (ON) across the terminal when the output is in standby
status and 24V (OFF) when the output activates.

You can also classify the output as monostable, in this way, it will be possible to define the output activation
time (ON Time). Once the set activation time expires, the output will restore to standby status
automatically but cannot be re-activated until the cause of activation clears.

If the activation time is not defined (“--”), the output will restore to standby status only when the cause of
activation clears.

Figure 4 - Output activation

Note: The outputs will be blocked automatically when you insert the programming jumper.

4.2 Controlling the outputs via the Inputs

Outputs OUT1, OUT2 and OUT3 are controlled respectively by inputs B1, B2 and B3.

The inputs are normally open (standby status), therefore, activation occurs when they are short-circuited
to GND.

4.3 How to use the power supply station

4.3.1 Stand-alone

In this operating mode the power-supply station is self-controlled, therefore, the outputs are managed via
the inputs. Fault conditions are signaled through the fault relay (FAULT output), which switches from
standby status to active status when faults occur.

4.3.2 Combined with an INIM Fire detection panel

There are two ways of connecting power supplies to INIM Fire detection panels, via:

•Loop connection

• RS485 BUS connection

Loop connection

This connection method allows the fire-defection panel to manage the power-supply outputs and fault
signals. The power-supply stations must be connected to the loop via one or more input/output modules
located inside the power supply station enclosure. The details of fault events can be viewed on the power
supply station display.

The following wiring diagram shows a loop connection using an input/output module of the INIM Electronics
ENEA series.

Figure 5 - Wiring diagram of a loop connection using a EM312SR module

Connecting the power supply station to an RS485 BUS

SmartLevel power-supply units are equipped with terminals which allow direct connection to the RS485
BUS of INIM fire detection panels. If any other devices are connected to the RS485 BUS, the power
supplies must be connected in parallel to them. The INIM fire detection panel will communicate with the
power supplies using a noise-immune communication protocol.

This connection method is designed to keep the control panel voltage isolated from the power-supply
station voltage.

The INIM fire-detection panel can enroll the power supply station, control its outputs as described in the
Table in paragraph 4.1 Controlling the Outputs and monitor its status (output and fault status). For details
regarding the respective wiring refer to paragraph 7.2 RS485 BUS wiring.

Note: If the power supply station is the last device on the BUS, you must insert the jumper JP3 in the EOL

position.

14 Functions and features

Installation and Programming manual

4.4 Protection circuit

The outputs are protected against short-circuit and overload (Imax=3.7A) by a protection circuit (circuit
breaker) which operates in the same way as a fuse.

If the protection circuit intervenes, the power supply station will signal the fault and protect the interrupted
line before making three attempts to re-activate it.

• If the fault condition (overload) clears, the output channel voltage will restore to 24V (ON).

• If the fault condition is still present after the third attempt, the power supply station will leave the
output at 0V (ALERT).

The three attempts to re-activate the line will be carried out at 2, 5 and 10 seconds from the start of the
fault.

In the event of a fault, follow the procedure described in paragraph 11.2 “Output protection” fault.

1. Connect the connection wire [A] to the two batteries.

2. Connect the wire [B] to the batteries.

Attention: Ensure that cable polarity is correct.

3. Connect the battery wire connector [C] to the power-supply module.

Attention: Ensure that connector polarity is correct.

The batteries are the secondary power supply of the system. The power supply station monitors the battery
status (efficiency and charge). The battery-test circuit of the power supply station operates as follows:

• Efficiency test
The battery-test circuit checks the efficiency of the batteries by simulating load current demand at 10
minute intervals. If the batteries fail to meet the load demand, the power supply station will signal a

Batt.discon. fault.

Additionally, the efficiency of the batteries is gauged by the value of their internal resistance (in
compliance with EN54-4:1997/A2). If this resistance reaches 2 Ohm, the power supply station will signal
a “

Batt.inef.” fault.

• Battery test
The battery-test circuit monitors the battery status (efficiency and charge) continuously. The battery-test
circuit can detect anomalies such as:

- A high charge voltage (“

Overload.”). This is signaled when the battery charge reaches 30V (the test

will not be carried out during mains failure conditions).

- A low charge voltage (“

Underload.”). This is signaled when the battery charge drops below 25V (the

test will not be carried out during mains failure conditions).

- In the event of mains failure, the power supply station will still monitor the battery voltage

continuously. If the voltage drops below 22.8 V, the power supply station will generate a “

Low batt.”

event. The event will end when the voltage restores to 24.6 V.

• Deep discharge shutdown

If a mains failure event lasts for a long period, causing the battery voltage to drop below 18 V, the power
supply station will shutdown the batteries in order to avoid permanent damage.

7.7 The thermal probe

Attention: In order to validate IMQ-SISTEMI DI SICUREZZA certification (Italian Safety and Quality

Certification) and EN 54-4 compliancy, use of a thermal probe is mandatory.

The thermal probe (accessory item) regulates the charging process in accordance with the battery
temperature. Use of a thermal probe prevents overheating and the consequent damage to the batteries.

7.7.1 Connecting the thermal probe

1. Disconnect the batteries.

2. Disconnect the output channels of the power supply station.

3. Connect the thermal probe to the connector (table on page 15, “[I] and Figure 12 - Connecting the
batteries, [D]).

4. Attach the thermal probe to one of the batteries, in such way as to provide optimized heat-transfer
measurements.

5. Hold a thermometer against the probe and measure the probe temperature.

6. Using the following graph, find the value the measurement will be based on.

Figure 13 - Charge voltage in accordance with the Battery temperature

7. Using the graph (refer to paragraph 9.2 Output status screen), or a tester on OUT [B], measure the
voltage. If the voltage is incorrect, use the trimmer [C] to adjust it to the correct value.

Troubleshooting

Attention: Only authorized operators Level 3 may rectify faults.

11.1 Current faults list

If faults occur, the power-supply station will provide the fault details on the display.

The first line on the screen shows the chronological order number of
the fault over the total number of active faults (the example shows the
first of six faults). The line below indicates the type of fault concerned.

Keys S and T will allow you to scroll the faults list.

To access the faults list from the presentation or status screen pressing Esc. To exit the faults list and step
back to the presentation or status screen press Ok.

Note: The list is not available when there are no fault conditions to report.

11.2 “Output protection” fault

This occurs when the power supply station forces the outputs to OFF
status (0V) as a means of protection.

Protection status can be triggered by short-circuit or overload (a
charge that exceeds specifications) on the output concerned.

There are two ways of restoring this fault, as follows.

• From the Maintenance menu

1. Insert the PROG Jumper.

2. From station: Ok, Maintenance, Ok, Booster ON/OFF, Ok
the power supply station will reset the Fault LED and the Fault relay.

3. Set the protected output to OFF.

4. Clear the fault on the output circuit in question.

5. Set the protected output to ON and wait until the power supply station restores the output
automatically. If the condition persists for more than 10-15 seconds, repeat the operation.

6. When the fault restores, exit the Maintenance menu (remove the PROG jumper).

• Using control inputs

1. Using the inputs (which control the outputs), force the output to OFF (0V) status in order to protect the
circuit. In this way, the Fault LED and the Fault relay will remain active.

2. Clear the fault on the output circuit.

3. Re-activate the output via the respective input, or carry out a reset operation (From the station: Ok,
Reset, Ok). Wait until the power supply station restores the protection status automatically. If the
condition persists for more than 10-15 seconds, repeat the operation.

4. When the fault restores, the Fault LED will start to blink to indicate that the fault details have been
saved to the memory. To stop the LED from blinking, reset the power-supply station. Re-activation via
reset (refer to point 3.) is unnecessary.

11.3 Battery Faults

11.3.1 Battery Disconnected or Inefficient

The battery is not connected (“Batt.discon.”) or has failed the
battery efficiency test (“

Batt.inef.”) (EN 54-4:1997 A2).

1. Allow the batteries to charge for several hours.

2. If the fault signal persists, disconnect the batteries from the panel and test them separately.

3. If just one of the batteries has a voltage below 12.5 - 13 V:

• Replace the faulty battery only.

• Allow the batteries to charge for several hours.

• Ensure that the fault has cleared.

4. If both batteries are @12.5 - 13 V, it means both batteries are inefficient (even though the voltage
without load is correct).

• Replace both batteries.

• Allow the batteries to charge for several hours.

• Ensure that the fault has cleared.

• With the batteries disconnected, ensure that the voltage on the battery connector ([B] in Figure 14 -
Charge voltage adjustment using a tester) on the power supply station is:

-27.6 V if the battery is not equipped with a thermal probe or,

-the value indicated in the graph Figure 13 - Charge voltage in accordance with the Battery
temperature, if the battery is equipped with a thermal probe.

• If the value is incorrect, use the trimmer ([C] in Figure 14 - Charge voltage adjustment using a tester)
to adjust it.

11.3.2 Low Battery

The batteries are running low.

This signal should be present only during primary power source failure
(Mains 230 Vac). Mains power must be restored in order to charge the
batteries.

11.3.3 Overload/Underload

The batteries have been improperly charged (the charge voltage does
not comply with product specifications (“

Underload.” or

“

Overload.”).

The power supply station triggers this signal when the primary power
source (mains) is present but the battery charge is insufficient. If this
occurs, check the output voltage of the power supply station and
adjust the battery-charge voltage.

11.4 Other faults

The display shows the message: Meaning

Mains fail.
