E-200 SERIES INTERCOM SYSTEM — EF-200 DUAL CHANNEL MASTER STATION
the system will leave the global mode, stopping blinking the associated LED to the buzzer switch.
If we want to leave the global mode without carrying out any of the functions previously
mentioned, we simply will press quickly the BUZZER switch and the system will leave the global
mode, stopping blinking the associated LED to the buzzer switch.
REMOTE MUTE ALL MICS AND BUZZER SWITCHES
These switches allow to disable all the microphones (ALL MICS) and all the
buzzers (BUZZERS) of both channels of the intercom system (including all the
beltpacks, desk station units and master station units) except the one from the
master station from that these switched are activated.
The remote mute ALL MICS switch carries out the function upon pressing it. This
means that the units (beltpacks, desk stations units, etc.) connected to the system can turn on the
microphones again when it’s required. When this switch is pressed, its associated LED turns on
during a moment.
The BUZZERS switch, on the other hand, carries out an on/ off function. If the remote mute
buzzers function was enabled, when the remote mute buzzers switch is pressed the remote mute
buzzers function is disabled and the associated LED becomes turned off (in this moment all the
external units could enable their local buzzers again); if, on the other hand, it was disabled, when
the remote mute buzzers switch is pressed the remote mute buzzers function is enabled and the
associated LED becomes turned on (at this moment the buzzers of all the external units will be
disabled and they can not be enabled again locally).
CALL SWITCH
The EF-200 master unit is provided with two call switches, one per intercom
channel. When one of these switches is pressed a call signal is sent to the
corresponding intercom channel. The call signal makes the LED associated with the
switch start blinking; if the buzzer is enabled (consult buzzer on/ off section for more
information) an intermittent sound takes place during three seconds (the LED blinking, as well as
the buzzer sound is different if the call takes place in the channel A or B), the same as in all the
units (beltpacks, desk stations, master stations, etc.), connected to the same intercom channel.
If the CALL switch is pressed continuously, the duration of the call signal will be higher (the
time that the switch is pressed, and approximately 3 seconds more).
If a call signal is generated in an external unit (beltpacks, desk stations, master stations, etc.),
the LED associated to the CALL switch of the channel in which the call signal is received, will start
blinking and if the buzzer is enabled (see buzzer on/ off section for more information) an
intermittent sound will take place during about three seconds.
MIC ON/ OFF/ PUSH TO TALK SWITCH
The EF-200 master unit is provided with two talk switches, one per intercom channel.
The TALK switch allows to enable/ disable the microphone, so that we are able to speak
with other units connected to the same intercom channel. If the channel A micro-phone
isn’t activated (for example), and the channel B microphone is activated, we will speak with
the stations connected to the channel B, but the connected stations to the channel won’t hear us.
If the microphone is activated, its associated LED will light up, and on the other hand, if it is
disabled, its associated LED will turn off.
The TALK switches have two operation modes. When this switch is pressed quickly, the
microphone changes its state; if it was enabled, being pressed it gets disabled and turns off the
associated LED, and if it was disabled, being pressed it gets enabled and turns on the associated
LED.
