Remote Control; Call Button - Federal Signal AudioMaster 310-MV Instrucciones Para La Instalación Y El Mantenimiento

PRIMARY MODE:
Each intercom can be configured as a Primary unit (Push‑to‑Talk) or a Secondary unit (Push‑to‑Listen) by
changing the MAS/SLA jumper (J7) on the printed circuit board (see figure 1). The intercom comes from the
factory set in the Primary (MAS) mode.
In the Primary mode the intercom acts as an amplifier, constantly broadcasting over its speaker any signal
that it receives on the signal lines. Holding down the Listen/Talk switch changes the unit from a speaker to a
microphone (see figure 2). The intercom will now transmit over the signal lines to additional intercom(s) also set
in the Primary mode. When the switch is released it will default back to the Listen or Speaker mode, allowing the
user to receive any messages transmitted back to it.
SECONDARY MODE:
Some applications may require that the intercom constantly transmit (i.e., act as a microphone) as opposed to
constantly receive (i.e., act as a speaker). To accomplish this the intercom must be switched into the Secondary
(Push‑to‑Listen) mode.
To switch an intercom into the Secondary mode there are three steps to follow.
Disconnect power to the intercom before any installation, maintenance, or configuration changes are performed.
Move the J2 jumper block on the P.C. board from the MAS to SLA position (see Figure 1). This can be done
using long nose pliers, pulling the block off the "MAS" and center position and placing it on the "SLA" and center
position.
An intercom configured in the Secondary mode needs to have the Listen/Talk switch default to the talk position
on the cover plate (see Figure 3).
The second change required is to rotate the position of the Talk/Listen switch. This can be accomplished by
loosening the rubber boot covering the toggle switch enough to allow the toggle switch to turn 180 degrees. The
dimple on the locking ring must seat itself in the locating hole (see Figure 4). The rubber boot is then tightened up
against the cover plate with the toggle switch leaning to the talk position, as shown in Figure 3.
The third change involves the interconnect wiring. When a unit is placed in the Secondary mode it defaults to
the Talk or transmit position. When hooked to a Primary unit it is necessary to override the Secondary unit in
order for the Primary unit to be able to transmit. The #6 pin (remote) on both terminal blocks (see Figure 5) must
be connected between the Primary and the Secondary unit. Paragraph G. WIRING DIAGRAMS contains wiring
diagrams of typical intercom configurations.

REMOTE CONTROL:

Remote control is used to change the operation mode of a remote intercom from listen to talk or from talk to listen
upon activation of a local intercom. The wiring diagram section illustrates Primary/Secondary Installation and Using
Foot Switches Diagrams. (See Figures 8 and 9.)
Normally open foot switches can also be connected to the Remote Control line in order to allow "hands free"
operation of the listen/talk functions.

CALL BUTTON:

Depressing the call button sends a 1 kHz tone onto the signal lines. All units listening to the line will then broadcast
this signal as a call.
The call signal is substantially louder than normal voice messages being carried on the line.
Do not depress the call switch while carrying on a conversation with someone on the system.
This will subject the listener to very loud sound levels.
