12. Speaker zone failure indicator.
Yellow
Change in speaker impedance in circuit A or B, or the zone may be open or short-circuited.
Off
Current impedance of the speaker zone loop is within the impedance measured when it was first installed.
Important note:
it is necessary to carry out a measurement and subsequent recording of the
impedance to obtain the value of the impedance of the speaker circuit of each zone, if we connect new
speakers we must do the measurement again.
The method is as follows: on the rear configuration switches turn down the seventh switch, wait until
you hear alternate beeps from the buzzer and see the fault indicator light blink on the front panel, when
finished raise the seventh switch. When an impedance variation occurs in the speaker circuit that
exceeds ± 10-30% of the impedance value recorded by the equipment, the impedance variation will be
recorded in the LOG and the user will hear a beep and the fault light will flash will light up yellow. The
detection sensitivity of the zones is equal to or greater than 20W.
13. Message indicator with the emergency microphone or microphone desk (PZ-500).
When giving a voice announcement in one or more zones, this indicator will turn on to notify us that a voice
announcement is being made.
14. Indicator that a voice evacuation message is being broadcast in a zone.
When an evacuation or alert message is playing the indicator will light.
15. Indicator that the zone is playing background music.
In general, it is recommended to first select the zone or zones where you want to hear an audio signal, and then
select the audio input to be played in these zones. This selection and redirection of audio input signals to zone
groups can also be done from the SF-500 software.
16. Zone selection button.
To individually select the six output speaker zones. If none of the zone output indicators are lighting in
"PAGING", "EVAC / ALERT" or "BGM", one of them will be turned on by pressing this key (the corresponding
LED light is on according to the current output audio level) .
Note:
If one of the zone indicator lights are on
PAGING
,
EVAC / ALERT
or
BGM
and is on, you can
close the zone output by pressing this key.
17. Attenuation of the output level of the output zone.
Increase or decrease the zone output volume individuallyup to 6 levels, with a maximum attenuation down to
-15dB.
18. Hand Microphone Input.
Input for emergency microphone or fireman's microphone with highest priority.
19. Monitor speaker attenuator.
Increase or decrease the volume of the monitor speaker.
20. Adjusting the output sensitivity of the handheld microphone.
Used to adjust the emergency microphone input sensitivity.
21. Treble control.
Increase or decrease the total treble output.
22. Bass control.
Increase or decrease the total bass output.
23. Master volume control.
Increase or decrease the overall volume level.
