IMPORTANT
:
Triggers on open circuit.
If either trigger wire is not used, it must be
grounded. If not, the unit will operate.
Note: You can program telephone
numbers and voice messages prior to
connecting power as long as the 9VDC
battery is inserted. The stand-by
battery will retain programmed
information and allow for
approximately 24 hours of operation.
1.Select a location for the dialer that is
near both an AC outlet and the alarm
control panel. Keep the E-920A out of
sight of intruders.
2.Connect to power:
a. If the dialer is to draw power from the
alarm control panel, connect the red,
black, yellow, and green wires of the
4-pin connector to the panel as shown
in the wiring diagram.
b. If local power is preferred, plug in an
optional 12VDC adapter. It is not
necessary to connect the red wire of
the 4-pin connector to the alarm
control panel. However, the black,
yellow, and green wires MUST be
connected.
c. For backup power, connect both the
red wire and the 12VDC adapter.
Note: The E-920A utilizes an EEPROM
to retain memory even in the event of
a power loss.
3.Two trigger inputs can be connected to
two separate alarm control panel trigger
outputs. Each trigger input has its own
voice message. The yellow wire (trigger
input #1) is for the first voice message,
and the green wire (trigger input #2) is
for the second voice message. The
messages should reflect the type of
emergency which the alarm's output
represents. The green and yellow wires
should be connected to separate N.C.
dry contacts on the alarm.
Note: If DIP Switch 5 is set in the OFF
position, the N.C. contact for trigger
input #1 or #2 must remain open in
order for the dialer to complete the
dialing cycle. In this case, the dialer
must be connected to a triggering
device with a timed output.
4.The dialer can be connected to a pulse
or touch-tone phone line via the included
telephone cable.
5. Once all connections have been made,
the unit is ready to be programmed.
