Dialer
he DialStat
TM
is a small, rugged, and simple, but powerful, device which easily
handles complex dialing notification and alarm monitoring. To accomplish these
tasks, DialStat

has an equally simple operator interface. Figure 1 illustrates the
controls and indicators of the dialer, and the following paragraphs describe them.
(1) FAULT LEDS in the upper middle indicate status for each of the four input channels:
GREEN (Steady) = Normal.
GREEN (Flashing) = Input returned to normal state, but is not yet acknowledged.
YELLOW = Input is in fault state, but alarm delay has not yet elapsed.
RED (Flashing) = Input is in unacknowledged alarm state.
RED (Steady) = Input is in acknowledged alarm state.
(2) ON/OFF SWITCH located in the upper right corner, turns the dialer on or off.
(3) RING/ACTIVE LED located adjacent to the LINE connector indicates call progress
while the dialer is off-hook and incoming ring detection when on-hook.
(4) LINE JACK is a standard RJ11 phone jack where an outside line is connected to the
dialer.
(5) AC POWER/CHARGING LED indicates that external power is present and is
charging the internal, standby battery
(6) OFF HOOK LED located adjacent to the PHONE connector is turned on whenever
the dialer senses that a telephone connected to the phone jack is off-hook, and
DialStat is ready to accept programming commands.
(7) PHONE JACK is a standard RJ11 phone jack used to connect a local phone--used
for entering programming commands--to the dialer.
(8) I/O TERMINAL BLOCK is used to wire external sensors to the dialer, and also
provides the local alarm contacts to external equipment.
(9) 12 VDC TERMINAL BLOCK for connecting 12 – 20 VDC Power.
