Compliance
Praesideo is compliant.
Praesideo provides an 'Indicator test' action that can be
configured for a key on a call station keypad or keypad
module. When activated all indications on that call station
and all its connected keypads are switched on to visually
check the indicators. Bi-color indicators alternate between
both colors. The call station monitor loudspeaker will sound
a single tone chime with priority 223. If a numeric keypad is
connected to the call station, its LCD shows an alternating
test pattern to visually check all pixels.
The installer must take care that indicators that are
connected to control output contacts are testable.
Praesideo is compliant.
The output power of the amplifier elements of the
Praesideo system (Power Amplifiers, Basic Amplifiers) are
specified in the data sheets and in the IUI.
The A-weighted signal-to-noise ratio of the Praesideo
amplifiers (Power Amplifiers and Basic Amplifiers) is
specified in the data sheets and in the IUI. The signal-to-
noise ratio is above 85 dB. The complete signal chain from
microphone to loudspeaker is compliant to this clause.
