drops between 11vDC and 9vDC, the transmitter’s

alarm will sound. The low battery alarm
will continue until 110vAC power is restored and the
battery voltage is recharged to greater than 11vDC.
The alarm is a single, one second beep that will sound
once a minute.
The LED on the transmitter that is green during
normal operation, will turn red indicating that there is
a 110vAC power failure and that the system is operat-
ing on 12vDC battery backup power. The red LED
will alternately blink ON for one second and OFF for
four seconds.
A fully discharged 5.0Ah battery will take five
times its projected operating time to completely
recharge. The battery will take about 50 hours to fully
charge. The transmitter automatically charges the
backup battery while the system is operating normally
on 110vAC power.
Note: How long it will take the battery
to recharge to 11vDC will depend on
how low the battery’s voltage has dropped and
how wide the signal field is. The lower the
voltage is and the wider the signal field is,
the longer it will take to recharge the battery.
Note: A battery will take five times its
rated operating time to fully charge.
A 5.0Ah battery will take about 50 hours
to charge to full power.
If the voltage of the battery drops too low to pro-
duce a signal field, the LED will not be lit.
Connect the twisted pair ends of the signal field
wire to the ICT 775. Strip about 1/4 inch(6.4mm) of
insulation off each of the two ends of the twisted wire.
Twist the exposed wire strands on each end of the
wires together to hold the strands together. You want to
make sure that a loose strand on one end of the wire
does not touch the other end of the wire, or or the other
opening in the wire connector, or any other component
on the transmitter’s circuit board.
Connect each end of the twisted pair to the ICT
775 signal field wire connector labeled LOOP.
Use your thumb to push back and down hard on
the white tabs located on top of the signal field wire
connector. While holding down the tabs,
put one stripped end of the twisted wire
into each of the openings in the connec-
tor. Either end of the wire may be put into
either opening. Hold the ends of the wire
in the openings and release the tabs. The
ends of the wire will automatically be
crimped into the wire connector.
Note: You will have to apply pressure
to push down the white tabs on the
connector; the connector will not break, so
do not be concerned about pushing too hard.
To remove the signal field wire from the connec-
tor, push back and down on the tabs on the connector
and pull the ends of the wire out.
Note: Before you turn on the power to
the ICT 775 system be sure that the
loop type selector switch is in the mode that you
will want it to be. Either the Normal position,
UP, for a closed signal field wire, or the 3 Side
position, DOWN for a three sided system.
