Two ways to enter emergency mode and broadcast an emergency message:
1) Activate the emergency mode by pressing the red button with cap. Immediately the red light will start
flashing. Then select all or those areas where you want to launch the emergency message, and press the
"EVAC MSG" or "ALERT MSG" button as desired.
2) The automatic emergency emission can be activated by closing any of the remote controls Trigger Inputs
on the rear panel of the SLA-500M control unit and the SLA-expansion units.
Two ways to exit emergency mode and restore normal operating mode:
1)Press the red capped button on the front panel to end the emergency mode and to end the emergency
message broadcast.
2) The automatic way to exit the emergency mode is with a direct short circuit to the Emergency Reset Input
on the rear panel of the SLA-500M, then the evacuation voice message playback will stop and the zone
outputs speakers will be disconnected.
Note:
It does not matter if it is a manual input or an automatic input, the operating time and its activation can
be checked and reviewed in the LOG of the SF-500 software.
8. FAULT /ACK Button
If any system module during diagnosis fails, the FAULT indicator flashes, press the FAULT / ACK button to
stop the indicator flashing and the buzzer, until the equipment works normally the FAULT will stay on solid.

Note:
1. If any user wants to manually play the evacuation voice message, they must enter emergency mode,
select the zone or zones where they want to launch the message, and then press the voice message
key (EVAC MSG or ALERT MSG ).
2. In the system, by default, the priority of "evacuation" is higher than the "alert". Of course, it can be
modified with the SF-500 configuration software. If it is not a specific installation need, please do not
change the priority.
10. Line input selector for speaker zone outputs.
It is mainly used to select the external line input on this equipment. SLA-500M main unit audio inputs can be
routed to the SLA-500S expansion module outputs, but expansion modules audio inputs can only be used in
their own zones.
Note: Routing audio from one input to the desired outputs can be done and checked using the SF-500
control software. You can also enable or disable individualized routing for each host of one of its audio
inputs to its zones, from its own front panel.
11. All zones selector.
If the current zones are off, they will all turn ON; If all zones are armed, they will all be disarmed (OFF).

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

monitored in real time, maximum capacity of 32 GB SD memory card. SD memory card supports a maximum
of 255 messages. Never handle this card with the equipment turned on. Do not delete or manipulate the files if
you are not sure, make a backup copy of the original files before making any changes, otherwise the
equipment may stop working and will not come under warranty. VERY IMPORTANT THE AUDIO FILES
MUST BE IN "WAV" FORMAT.
In the root directory of the SD card there are 3 folders:
- BGM folder for music.
- EVAC folder:
"alert_message" where the alert message is. To
change the alert message we must replace the
audio file by putting the new file (WAV) with the
same name as the one originally in the folder.
“evac_message" where the evacuation
message is stored To change the evacuation
message we must replace the audio file by putting
the new file (WAV) with the same name as the one
originally in the folder.
"log" where the event log is stored. where the equipment configuration is stored. VERY
IMPORTANT DO NOT HANDLE THIS FOLDER.
"parameter_disable_del" where the equipment configuration is stored. VERY IMPORTANT DO NOT
HANDLE THIS FOLDER.
- PROMPT folder: within this folder are the "Ding Dong" warning tones that are emitted at the beginning and at
the end of voice messages, the warning tones can be modified according to customer requirements and be
replaced by others (Format WAV) these tones are for all notification desks, these warning tones are not
supervised in real time, they are only supervised once when the equipment is turned on, so if there are no
warning tones or the file has been lost, do not will be warned as a failure.

1. When a voice announcement is being made, if we press this button, the voice announcement will end;
2. When there is no voice prompt and a zone is selected, press this button to start the voice prompt
(you need to wait for the microphone light to turn on).
Note: If the microphone is in PTT mode, it will be necessary to keep pressing the button, otherwise the
voice announcement will end (PTT this mode is explained in point "11" of this manual, later).

Nota:
1. If the PZ-500F, PZ-500, PZ-500P or SLA-500S cannot communicate normally with the main
equipment (SLA-500M), activate the end-of-line resistor of the last connected equipment at the end of
the line. The PZ-500F firefighters microphone cannot be the last equipment in the installation, this
resistor is only for star wiring not for loop-type wiring.
2. If the installation is like Figure 2, the resistor should not activate.

Operation guide
Background music broadcast
Connect the audio sources or microphones to the inputs on the rear panel, select the line input via
the input source selector on the front panel of the main equipment or expansion equipment, connect the
zone output with the corresponding background music indicator means that music is playing in that area.
Note: Emergency messages and microphones are common between main equipment and
expansion equipment, while line inputs 1-6 are only for the equipment itself.
Automatic emergency broadcast
From the normal state, connect a fire panel or other external control equipment to the 8 control input
terminals (Trigger inputs) of the main equipment or an expansion one. The control input terminals receive a
contact from a fire panel or other external control equipment and then a general emergency message will be
issued. At the same time, a control output will be activated on the control equipment to activate third-party
equipment. There are two kinds of control inputs, by contact (short circuit) or by voltage level. Press the
emergency button or remote reset input again to end the emergency broadcast.
Manual activation of the emergency message
Press the emergency button, it will light up red, then select the zone and press the EVAC MSG or Alert MSG
button. For the manual emergency broadcast to work the message indicator light and the zone evacuation
light must be on. Press the emergency button or remote reset input again to end the emergency broadcast.
Warning with the emergency microphone
Press the side button of the emergency microphone to make the
emergency announcement to all zones at any time (in the process the
user can manually activate or deactivate the loudspeaker zones, by
default all partitions and zones are activated), the tone The pre-
announcement will sound first and the EMG microphone indicator will
light indicating that it is ready for the emergency announcement,
release the microphone to end the voice announcement. This
emergency microphone circuit is always supervised in real time.
General announcement or by zones of a microphone notification desk
Select the zone or ALL (in the selected zone or zones the green LED will flash), press the call button to make
the voice announcement with Chime (the green zone LED will light up steadily). Under PTT mode, the call
button must be held down to make any voice announcements.
