5.11.3.3 Power supply
The power supply circuit controls the power supply and the power supply outputs, and also manages the battery.
More specifically, when the battery is charging, it carries out the efficiency test and, when there is a blackout, it
disconnects the battery when the voltage to the battery terminals reaches about 10.5 V, thereby protecting it from the
deep discharge.
The battery will be automatically recharged when the mains power supply is restored.
By referring to the
Figure 54 - 1067/092 Board , the functions of the terminals and LEDs dedicated to the Power supply
are the following:
Terminal

Group Terminal Connection / Function
M5 Battery
+BT Back-up battery power supply input (positive pole)
- BT Back-up battery power supply input (negative pole)
M6 Power supply
+PS Power supply input (at the positive terminal of the power supply)
- PS Power supply input (at the negative terminal of the power supply)
M7
Outputs
Auxiliaries
+SR
Power supply (14.4 Vdc limited to 200 mA) for recharging the batteries of the
self-powered devices (ex. sirens).
It is possible to connect up to 2 self-powered sirens.
Important: In case of blackout, +SR supplies no voltage, therefore it must be
used only to connect self-powered devices.
The self-powered devices must have a positive anti-return diode in series.
Note : all the Urmet self-powered actuators come equipped with this device.

5.12 CONNECTIONS
This paragraph contains instructions on how to carry out all the electrical connections and necessary signals for starting up the
system.
IMPORTANT! Before running the cables, check that the sections are correct and that conform with the maximum
distances. If in doubt, consult paragraph 4.1 .
IMPORTANT! The end of the stranded conduction must not be consolidated with a soft-solder welding in the
points where the conductor is subject to contact pressure.
Therefore it is not allowed to solder the terminals of the cables connected to the terminals of the devices.
5.12.1 230 Vac power supply line
IMPORTANT! Before making any connections to the mains power supply, disconnect the mains power supply.
In fulfilment of the electrical safety standards for 230 Vac power supplies, a suitable isolating device must be installed,
like a double-pole thermo-magnetic circuit breaker to protect the mains power supply (
Figure 55 - Diagram of the
connections to the mains power supply ).
It is advisable to position the circuit breaker upstream from the differential switch (the so-called "automatic cut-out
switch), in order to be able to disconnect other sections of the electrical system, thereby maintaining the functionality of
the systems.
For the 230 Vac power supply, use a 2 x 1.5 mm
2
cable.
The 1067/024 and 1067/032A control panels have double isolation and do not need earths (PE). However, the earth
connection is required only for the connection to the telephone line.
The 1067/052A control panel and the 1067/092 power supply require, instead, an each connection (PE) made with cable
of a section no less than that of the cable used for the power supply. For this connection, there is a Faston connector
provided with the control panel.
