Note: Without an acknowledgement, the message will be
repeated until the maximum number of message repeats is
reached (see Location 20 in Para. 5.8). The dialer will call the
remaining numbers and will then repeatedly retry the number
that didn't acknowledge, until the maximum number of dialing
attempts is reached (see Locations 12 and 13).
F. After acknowledgement, the dialer enables the "listen in"
function for a preprogrammed period.
G. At the end of the listen-in period, a short beep sounds. If the
called party keys "1" within 10 seconds, a new listen-in period
begins. Otherwise", the dialer will go "on hook". The listen-in
period may be prolonged as many times as necessary or
terminated at any time by keying "9" twice in succession.
H. Upon conclusion of the communication session with the first
telephone, the procedure in A through G above will be
repeated for all remaining telephone numbers in the relevant
group (provided that the "non-backup mode" has been
selected in Location 24).
Note: Location 24 allows selection of "backup" or "non-
backup" mode. In the backup mode, acknowledgement from
one telephone is enough to close the event. In the "non-
backup" mode, acknowledgement must be obtained from all
telephones in the group.
I. Once the entire communication cycle is concluded, the dialer
disengages the line and reverts to the standby state. If you
are using the DL-125C, the communication routine may be
aborted at any time by pressing the STOP button on the
keypad (provided that the input is no longer in alarm). If you
are using the DL-125CA, the only way to stop the dialer is to
disconnect the power, because the STOP button is disabled.

4. Wiring
The dialer can be powered by constant power supply or by a
switched power supply. When the dialer receives switched power
from an alarm system, it will be disabled upon stopping the alarm,
since the alarm relay cuts off the power. This type of wiring is
ideal when the dialer is mounted in a locked box that prevents
access to the STOP pushbutton.
Note: Both Z-1 and Z-2 inputs can be programmed as N.O.
(normally open) or N.C. (normally closed) inputs (see Locations
22 & 23 in Para. 5.8). With N.O. inputs selected, a short circuit
across the relevant input will activate the dialer.
With N.C. inputs selected, an open circuit across the relevant
input will activate the dialer.
Use 15 AWG or larger conductor to connect the EARTH terminal
to the nearest electrical ground, preferably a ground rod.
Failure to earth the unit compromises safety!
The phone connected to the SET terminals will be automatically
disconnected from the line whenever the dialer goes into action.
