7. Operation

Pushbutton Operation

When the pushbutton of the ETP-120 Series Call Station is pressed, the unit will go off-hook and dial up
to five (5) pre-programmed phone number(s) in round robin fashion if a phone number is busy or does
not answer.
The "ANSWERED" LED momentarily flashes while dialing.
When the call is answered, the voice message (if recorded) will automatically play to identify the
physical location of the phone call. The unit by default plays the voice message once, and then
automatically illuminates the "ANSWERED" LED to indicate that hands-free communication to the
answering point has been established.
During an active call, if the remote side (answering point or receiving end) presses the * key, the unit
will transmit the ID number (if programmed), then play the voice message again. The remote side will
then be advised of the physical location of the phone call through either the voice message or the
information displayed in the Talk-A-Lert software when it decodes the DTMF ID number.
Once the "ANSWERED" LED is activated, the # key can be used on the remote side to terminate the
call or hang up the ETP-120 Series Call Station.

Auxiliary Input Operation

The Auxiliary Input allows for remote call activation on the ETP-120 Series Call Station via a dry contact
closure. Examples of external devices that could provide this dry contact closure include Model SA-1
Scream Alert, an elevator emergency stop button, a sensor for a stuck elevator or open elevator door,
smoke detector, alarm switch, etc.
When a dry contact closure is provided to the Auxiliary Input, the unit will go off-hook and dial up to
three (3) pre-programmed phone number(s) in round robin fashion if a phone number is busy or does
not answer.
The "ANSWERED" LED momentarily flashes while dialing.
When the call is answered, the unit will automatically illuminate the "ANSWERED" LED to indicate that
hands-free communication to the answering point has been established.
The voice message feature is NOT supported on the Auxiliary Input.
Once the "ANSWERED" LED is activated, hanging up the handset or pressing the # key on the remote
side phone will terminate the call.

Calling the ETP-120 from the Remote Side

1. On a regular touch-tone telephone, enter the telephone number of the Phone you wish to call. After
a short pause, the unit will answer with an open channel (i.e. microphone and speaker are active).
2. Begin speaking to any person at the unit.
3. Hang up the handset on the remote side to terminate the call.
NOTE:
The # key cannot be used to terminate inbound calls to the ETP-120 unit.
