POWER SUPPLY TUL500EN
CERTIFIED with the standard
EN 54-4:1997+A1:2002+A2:2006
EN 12101-10:2005
Installation Manual
GENERAL FEATURES
The Power Supply TUL500EN has been designed to be used as a Power Unit with power backup in Fire
Alarm Systems, in conformity to regulation (EU) No 305/2011 and how power supply equipment in systems
for smoke control and heat.
Its mechanical and electrical features make it complying to EN 54-4: 2007 Standard (Fire Alarm detecting
and signaling devices. Part 4: Power supply devices) which includes A1:2002 and A2:2006 updates.
FUNCTIONAL FEATURES
The power supply unit is made by a switching power supply, limited in constant precision current (rectangular
limitation), two 12 V 17 Ah batteries (not included) digital and analogical control circuit and micro-
controlled supervision circuit.
Power is available on 3 terminal-outputs protected by electronic fuses: A, B and C, for generic loads and one
connection BATT (with fuse): for back-up batteries. When a fuse trips, the corresponding LED on control
board (see Pict.2, DL1, DL6, DL7, DL8) will turn ON.
Electronic fuses try periodically to restore the power output: if an overload is removed, the power will be
available within 10 sec max.
The battery charge occurs at constant current (1 A) until the battery voltage reaches its nominal value (27,6
V @ 25° C), with temperature compensation. Maximum current supplied by the unit is 5 A, where 4 A is
for charge and 1 A is for recharging the battery.
The power supply is able to give 7 A peak for 25 seconds @ 25°C.
Four LEDs show the loads current consumption (3 green and 1 red: DL2, DL3, DL4, DL5)
One LED shows the Mains presence (LED1)
Check of battery efficiency
The power supply periodically carries out the efficiency of the batteries:
- At first activation of the power supply, the microprocessor will carry out the test of battery presence
after about 20 seconds. If connected, the test will be carried out every 10 minutes whilst in case it is
not connected, it will continue carry out the test every 20 seconds showing indication FAILURE.
- During normal operation, the battery efficiency is checked by controlling the batteries voltage. If
batteries do not manage to maintain an acceptable voltage during test, there will be the indication
FAILURE.
- A test of the battery internal resistance is carried out within 15 seconds after the battery connection
and then repeated every 2,5 hours, at least (in conformity to attachment EN54-4/A2); if the internal
resistance is over 1 ohm, there will be a FAILURE indication. With internal resistance failure
detected, this test is repeated every 5 minutes at most 5 times, to ensure recovery from spurious
failure detection. It will then be necessary to replace the batteries and check that terminals and fuses
have a good electrical contact. When the battery is replaced, the user should wait 15 seconds after
battery connection, with presence of mains voltage, for the repetition of the test and check if the
failure is removed. It is possible repeat the test by pressing the button on the back of front panel
display board for more than 2,5 seconds.
-
A microcontroller system controls various possible anomalies and gives a FAILURE indication in the following
conditions:
1. Output Fuses or Battery fuse interruptions
2. Overloaded Battery (> 28,3 V )
3. Low Battery Voltage (< 20,8 V )
4. Mains power supply absence and no battery charge
5. Disconnected Battery
6. Internal battery resistance >1 Ω
Failures are displayed on a frontal board; the detailed failure is showed on the internal power supply board.

MA-AL-T500-01-07 Manual TUL500EN eng rev7 Page 2 of 8
In order to avoid that a possible failure in the regulator damages the charges or the battery, a protection
circuit has been inserted against over-Voltages, made of a SCR and a fuse. A fuse for mains alternated
supplying is also present.
In case of failure in the power supply or of mains missing, the logic and control circuits are supplied by
batteries.

SECURITY INSTRUCTIONS
1. For mains input and DC outputs + alarms, use separate holes on the bottom of the box to pass the
cables. Furthermore, the material of the joint pipe/box must have a flammability class V-1 or better
2. The relay contact “GUASTO” and “RETE” must be connected only to circuits operating with SELV
Voltage.
3. For AC supplying, provide an omnipolar switch of the power supply network compliant with Annex L.
of IEC 62368-1 (separation between the contacts of at least 3 mm), easily accessible.
4. The wires must have a section of 1,5 mm and be equipped with adequate buttonholes where they are
subject to pressure contact.
5. The installation of the power supply must be carried out by qualified personnel aware of the security
standard IEC 62368-1 and concerning power supplies CEI-64-8.
INSTALLATION
Mechanical mounting
This device has to be mounted on vertical stable walls, suitable to support the power supply, by means of 4
screws with 8 mm diameter, for spacers and screws on the 4 holes on the bottom of the box. The battery

SYSTEM RUNNING
Battery voltage is monitored continuously, if the voltage drops below V(B)low = 20,8 V , the relay
“GUASTO” turns on and the Front panel “Battery Low” lights on.
If the voltage drops below V(B)min = 19,8 V , the battery is isolated to avoid the deep
discharge. After the battery gets unplugged, the battery will be connected to the system if the
voltage is higher than 16 V .
Battery internal resistance is tested every 2,5 hours, at least. If the resistance is higher than 1 Ohm a warning
in raised. The Front Panel LED “Failure” is lighted on, the LED “Overcharged battery”
slow flashes and the internal DL1 quick flashes.
Battery Fuse monitoring, in case of fault of the fuse, the LED “Low battery” starts to flash slowly. When the
fuse is replaced the signal disappear.
Fuses monitoring, if a fuse became open the LED lights on, when the cause of fault disappears the LED
lights off.
Mains monitoring, when the mains is missed, The Front Panel LED “Mains” is lighted off, and the relay
“RETE” is activated. When the mains return LED “Mains” is lighted on, and the relay “RETE”
is restored.
SERVICING
Periodical programmed servicing must be carried out by qualified personnel in order to prevent the possibility
of a malfunctioning of the power supply. It is recommended to carry out servicing every 6 months and to
evaluate control panel of the system in order to check possible alarms during tests.
- Check the connections of the 230 V~ supplying lines
- Check the connections of the alarm indication lines and related shields
- Check the battery connections, they have to be well tightened and there must be no oxidation
- Check the output Voltage on the charge (see electrical specifications)
Although the power supply is equipped with a self-diagnosis system carrying out a periodical control of the
battery and indicating possible failures, it is suggested to manually check the battery every six months.
- Disconnect the battery and check if the voltage of the power supply is within the values shown.
- After re-connecting the battery, disconnect the primary supplying and check if the battery can
maintain the Voltage on the higher 23 V charge. On the contrary, replace battery immediately.
- Check presence of related alarms during tests.
