1.2 The system parts and definitions
Switching power supply: this unit, starting from the mains power supply (230V ) it connects to,
supplies the board with a 24V (27,6V ) stabilized current capable of feeding the control panel and
recharging the batteries. The power-supply module is located below the mother board and is EN54-4
compliant. the mains power supply (230V ) the primary power source of the system. Refer to paragraph
5.2 Internal devices.
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 (amendment A2). In the event of primary power failure (230V ), the
batteries will take over automatically. If the problem persists for a long period thus causing the battery
charge to drop below the minimum value required, they will be shutdown automatically in order to avoid
damage. Refer to 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. Refer to
paragraph 7.7 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 twisted cable must be used for all
connections. Refer to 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 3 - 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:
•Loopconnection
• 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 from INIM Electronics
s.r.l. ENEA series:
Figure 4 - Wiring diagram of a loop connection using a EM312SR module
Connecting 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
Power supply stations
4.4 Protection circuit
The outputs are protected against short-circuit and overload 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.

Outputs OUT1-2-3 supply 24V (27.6V ) and a maximum current of 1.3A for the SPS24060G model and
3.6A for the SPS24160G model. These outputs can be used to power external devices.
These outputs can be managed via inputs B1, B2, B3 or via the RS485 BUS of an INIM fire-dectection panel
(refer to paragraph 4.1 Controlling the Outputs).
Use NON-shielded cable. The wire section should be compatible with the wire length and load connected to
the output.
7.4 Connecting the FAULT output
The FAULT output provides a voltage-free terminal which switches 1A 30V loads. The relay is energized
during standby status and closes its common contact to NC. During fault events, the NC contact opens and
the common contact closes to NO. The common contact closes to NC only when all fault conditions clear or
when the PROG jumper is inserted.
Note: The relay contacts on the electronic are suitable for SELV circuitry only.
7.5 Connecting the mains power source
The power system of the SmartLevel stations is EN54-4 compliant.
Danger: DO NOT power up the system with a non-compliant voltage.
1. Connect the mains power supply to the terminals on the power-supply module (Figure 9 - Switching
power supply, [A] and Figure 13 - Earthing system, [A]).
For a safety standards compliant system, the Line must be connected to terminal “L”, the Ne ut ral
conductor to terminal “N”.
This station must be connected to a separate line on the Electrical Switchboard (Mains power supply).
The line must be protected by a sectioning device which complies with local safety regulations, fire
codes, laws and bylaws in force.
Note: As a further safety measure, the electrical system of the building must be protected against overload
and short-circuit.
Note: The ends of wires must not be soft soldered in points where they are subject to clamping.
• Primary power source: 230 V (-15%/+ 10%) 50/60 Hz.
