SMC02G/SMC02F/Variants - Product Manual
1 Description
The SMC02G and SMC02F are robust flush mounting Station Master’s Consoles suitable for mounting in 19”
DIN equipment racks or other flat surfaces. The SMC02G has a panel mounted gooseneck microphone with
a console mounted Push To Talk switch, and the SMC02F has a fist microphone with integral Push To Talk
switch.
These microphones are designed to work with the whole range of ASL Voice Alarm and Public Address
systems, and are typically used by the Station Master for making announcements to any of the PA/VA zones
within a station.
The standard SMC02 units have the facility to act as a ‘Fire Microphone’ and activate the Router’s bypass
mode as required by BS5839 Pt 8. These units should be connected to Router’s inputs 1 and 2, which
operate in the All-Call failsafe override mode in the event of processor failure.
The ‘S’ variants (SMC02GS and SMC02FS) do not have the facility to act as a ‘Fire Microphone’, and are
configured as a normal ‘Paging Microphone’. These can be connected to any of the Router’s Mic/Line inputs
which support the required number of microphone buttons.
A flexible listen-in facility is also provided, whereby a mix of all zones or of selected zones may be monitored
via the SMC's built-in loudspeaker.
In a system which is configured with more than one SMC unit the listen-in facility can be controlled from only
one of the SMCs, i.e., the listen-in switch should only be configured on the primary SMC. However the listen-
in facility can also be controlled by a SMS/HCI type system connected to the Router’s host port. Although
only one SMC can control the listen-in facility, the listen-in audio is still available on all SMC units in the
system.
Microphone audio is provided as a balanced 0 dBu (nominal) analogue signal. The unit features an in-built
signal limiter to accommodate varying operator techniques.
An outgoing 20 Hz surveillance tone is generated to enable the audio cabling to the router to be monitored.
A multi-pole connector provides field connections.

1 Microphone
• SMC02G and SMC02GS:
Gooseneck microphone
• SMC02F and SMC02FS:
Fist microphone with integral Push To Talk button
2 SPEECH LEVEL METER
A LED bargraph speech level meter where the LEDs light in turn to indicate the sound pressure
being received at the microphone. This meter is annotated to indicate the correct speaking
level. The meter operates continuously, to allow the operator to ‘practice’ achieving the correct
level before making a broadcast.
3 PA LISTEN-IN VOLUME SWITCH
This switch controls the volume of the listen-in audio from the microphone’s listen-in speaker.
4 PA LISTEN-IN LED (green)
Illuminates while the listen-in mode is active.
Note that normal paging is not possible while listen-in is active.
PA LISTEN-IN LED SWITCH
Pressing this switch once will activate the listen-in function, such that all active audio from all
zones in the system is mixed and output from the microphone’s listen-in speaker.
Pressing this switch while holding down a zone select button will cause only that zone to be fed
to the listen-in speaker. Pressing subsequent zone buttons will add their audio to the mix. Re-
pressing buttons will de-select their zones from the mix.
Pressing the listen-in switch a second time will cancel the listen-in function.
5 BUSY LED (red)
One BUSY indicator LED is located adjacent to each of the ZONE SELECT BUTTTONS, and
when lit they indicates that the zone (or one or more of the group of zones) addressed by the
button is already in use by another input. This microphone can only select the zone if the other
input is of a lower priority.
If a higher priority input selects a zone during a paging announcement from the SMC02, then
the zone will be deselected for the SMC02, and the BUSY LED will illuminate. The
announcement will however continue to any other zones if the SMC02 is broadcasting to a
group of zones.
6 SELECT LED (green)
One SELECT indicator LED is located adjacent to each of the ZONE SELECT BUTTTONS, and
when lit they indicate that the zone (or one or more of the group of zones) controlled by that
button has been successfully selected, and is ready for use by the Microphone.
When a ZONE SELECT BUTTTON is initially pressed to select a zone the SELECT LED will
flash.
Once the Press to Talk (PTT) button is pressed and a broadcast is being made, then the
SELECT LED will stop flashing and will be steadily lit (as long as a higher priority input has not
selected the same zone).
If a higher priority input selects a zone during a paging announcement from the SMC02, then
the zone will be deselected from the SMC02 and the SELECT LED will go out. The
announcement will continue to any other zones if the SMC02 addresses a group of zones.
7 ZONE SELECT BUTTON
Selects which zone(s) will receive the paging announcement from this microphone unit. If
pressed a second time, the zone (or group of zones) will be de-selected.
Each Zone Select button can be configured to control a single zone, a group of zones, or all
zones.

8 ZONE IDENTIFICATION LABEL
This label carries the name or description of the zone (or group of zones) which is selected by
the adjacent Zone Select button.
A template for printing these labels is available from the “Data Downloads” page of Application
Solutions website: www.asl-electronics.co.uk/downloads.
9 SPEAK NOW LED (green)
When the Press To Talk (PTT) button is pressed, and the chime (if programmed at the Router)
has finished, then these LEDs are lit to indicate that the announcement can now be made by
speaking into the microphone.
10 PUSH TO TALK BUTTON
The Press To Talk (PTT) button is integral to the fist microphone on SMC02F units, and fitted
onto the microphone console on SMC02G units.
When pressed, it activates the zone selection, opens the microphone channel and triggers the
pre-announcement chime (if selected at the Router) ready for the paging announcement. When
released, the microphone channel is closed and the zone selections cancelled.
11 ALL CALL ONLY LED (yellow)
These LEDs illuminate if a processor or communication failure occurs with the standard SMC02
units. Pressing the Press to Talk (PTT) button in this mode causes a broadcast to all zones, via
the Router’s hardware bypass.
This LED and emergency bypass function are not functional on ‘S’ variant paging microphones
(SMC02GS and SMC02FS).
12 SYSTEM FAULT LED (yellow)
Illuminates if any fault is present on the PA/VA system.
Note that this does not indicate that the SMC02 is not working. A fault may be present with a
fully operational system, for example, if an amplifier has failed but has been automatically
replaced by a standby amplifier.
13 POWER LED (green)
Illuminates to indicate that unit is receiving DC power.

go ahead with the broadcast if it is not important for the
broadcast to definitely be heard in the affected zone or
zones. It is possible that the other audio source could be
of lower priority, and therefore be overridden by the
SMC02 microphone, however it is not good practice to
routinely override other announcements in general day to
day usage.
Note that the above is the standard LED indication

‘All Call’ at the Router. When an ‘All Call’ button is
pressed, all outputs, which have been configured
as being affected by any zone selection buttons on
the microphone, are selected for broadcast from
the microphone, i.e. the button press has the same
effect as if all zone selection buttons on the

Recommendations for Optimum Results
Speak slowly and clearly while observing the correct
positioning of the microphone in relation to your mouth:
a. Gooseneck microphone:
Speak at a normal conversational level positioning
the mouth 5-10 cm from the microphone capsule.
b. Fist microphone:
Speak at a normal conversational level with the
mouth directly adjacent to the Fist Microphone
capsule. A lip-guard is fitted to the front of the Fist
Microphone, which should be placed directly above
the top lip.
The SPEECH LEVEL meter indicates the sound pressure
being received at the microphone, and is annotated to
indicate the correct speaking level.
On VAR4/12/20 a ‘cough timeout’ is configurable. If
the ‘cough timeout’ has been configured at the
Router, then the PTT button can be released to
stop the broadcast while the user coughs, and then
re-pressed to continue the broadcast. The PTT
button must be re-pressed within the configured
cough timeout, or the broadcast will be ended.
 If a higher priority input selects a zone during a
paging announcement from the SMC02, then the
zone will be deselected from the SMC02 and the
SELECT LED will go out. The announcement will
continue to any other zones if the SMC02
addresses a group of zones.

2.2.2 Routing Digital Voice Messages (DVA Routing Buttons)
The ‘DVA Routing’ button function enables simple control of a single broadcast route, or complex broadcasts
to be set up. For instance when a button is pressed a route can be made that connects any desired
combination of audio inputs to any combination of outputs. Audio inputs are typically DVAs, however other
types of inputs such as microphone and background music can also be routed.
An example of this is a button programmed to cause an EVACUATE message to be broadcast in one zone,
and simultaneously cause an ALERT message to be broadcast to adjacent zones, while all remaining zones
are unaffected. Another example would be a set of ‘DVA Routing’ buttons which controls background music
broadcast to selected zones in the system.
• ‘DVA Routing’ buttons are only supported on microphones connected to VAR Router’s
Mic/Line inputs 1 or 2.
• ‘DVA Routing’ buttons are not fully operational when the standard SMC02 units are
operating in All Call Only failsafe override mode.

2.2.3 Playing Digital Voice Messages (Play DVA Buttons)
The button function is ‘play DVA to selected outputs’. When the button is pressed a route is made connecting
a DVA audio source from the Slave Unit or the Audio Control Unit (ACU) to outputs which have been pre-
selected using buttons configured for zone selection.
The ‘Play DVA’ button can be considered a variant of the ‘DVA Routing’ button, which routes only one DVA
audio source, and requires the zones to be pre-selected using Zone Select buttons.
