56-Siren calibration
The siren calibration allows the panel to calculate the required impedance
tresholds for the connected siren. The treshold values are stored in the panel and
used to ensure reliable siren fault and tamper detection.
Siren: 1-External, 2-Internal, 3-Strobe
Siren:
To start the calibration, choose the appropriate output first.
This starts the appropriate output measurement.
The calibration may cause one of the following messages.
Table 13: Calibration errors
Message
Cause
AS391V - No calibration required
In case of the VdS compatible sirens the calibration is not
applicable
Calibration Failure
Impossible to set power supply >12 V
Impedance is too low
The siren impedance is below the required minimum
Impedance is too high
The siren impedance is above the required maximum
If the siren impedance is acceptable, the panel calculates the allowed treshold.

The panel calculates two allowed impedance ranges, one for mains supply, and
another one, wider, for battery supply.

Notes
• This data is stored in the panel non-volatile memory. It can be changed during
another siren calibration, or by setting the panel to the factory defaults. See
“14-Defaults” on page 113 for more details.
• If the siren has not been calibrated, the panel detects siren faults using the
defalut values. In this case the siren fault detection does not comply with the
EN 50131 regulations.
• The calculated values can be requested and displayed via the management
software.
