4.2.5 Sizing of audio Bus
Whenever vocal keypads are used, it is necessary to connect them to the 1067/012A - 1067/012B vocal synthesis board,
which must be added in the 1067/024, 1067/032A and 1067/052A control panels. To connect the audio bus, only a
cascade connection can be used, beginning at the control panel.
The total length of the audio bus must not exceed 300 metres.
IMPORTANT! The use of the vocal card invalidates the EN50131 certification.
4.2.6 Sizing of Input/Output connections
The length of the cable connection between the detector or the actuator and the input to which it is connected must not
exceed 500 metres.
If the device should be connected to an input configured for fast pulses (rollers, shock etc.), the length of the
connection must not exceed 100 metres.
4.3 CONTROL CRITERIA OF THE MAINS POWER SUPPLY VOLTAGE
The 1067/024, 1067/032A and 1067/052A systems constantly control the presence of the mains power supply in the
control panel, which is detected by means of the presence of voltage in the power supply unit.
The absence and return of the mains power supply generate the following behaviours.
4.3.1 Blackout event
When the absence of the mains power supply is detected:

The alarm system is powered by the battery.

The green power supply LEDs of the keypads flash to signal the problem.

The event is recorded in the Diagnose Log.

The system does not generate an alarm immediately, but starts the "T Lack of power" count (1 hour). This parameter
can be modified during programming. Every time electrical power is restored, the "T Lack of power" count is reset to
zero.
The delay determined by the "T Lack of power" serves to prevent the sending of alarms due to brief interruptions in the
mains power supply.
This is particularly useful in those places where temporary blackouts are frequent. In this way the sending of a telephone
message to signal a brief blackout and a successive call at the time power is restored are avoided.
4.3.2 Continued blackout alarm
If the blackout persists until the Time of the Lack of power set expires, the following occurs:

The system generates a “Continued blackout alarm”.

The specialised lack of power output
s are activated (“LACK OF POWER”)

A dedicated alarm message is sent via the telephone transmitter.

The alarm is memorized in the Diagnose Log.
IMPORTANT!
If the battery level descends below the threshold of 12.5 V, the “Continued blackout alarm” is
generated immediately, even if the time Lack of power has not yet passed.
4.3.3 Restoration of the mains power supply
Once the mains power supply restores power, the green power supply LEDs of the keypads stop flashing and remain on
and the system restarts a time count. Once 5 minutes have passed, if the power has been continuously present, the
following occurs:

Via the telephone transmitter, the message dedicated to the restoration of mains power supply is sent.

The event of the restoration of the mains power supply is memorized in the Diagnose Log.
Potential brief interruption in the mains power supply during the time count will result in the resetting of this time.
4.4 BATTERY MANAGEMENT CRITERIA
The system is capable of detecting all the possible conditions under which the back-up battery may be needed and to
provide for its management adequately in automatic mode. The detection is based on the voltage read at the battery
terminals
+BT and
–BT
.
The control carried out on the status of the battery is done in two ways, depending on the presence or absence of the
mains power supply.
4.4.1 Control and charging of the battery with the mains power supply present
The 1067 systems, when the mains power supply is present, provide constant control of the battery. If the battery is not
detected, or if it is completely dead, the system assumes the status of
“No battery”. In this status the battery charging
circuit is turned off: this means that if the battery is not connected to the terminals of the connection cables, (red and
black faston) there is no power. As soon as battery is connected, the charging circuit is once again activated and keeps
the battery charged with a limited maximum current.
Note: If due to some anomaly the battery should reach a charge of 14 V, the charging circuit is automatically deactivated
to prevent damage to the battery.
