ICT 725 Transmitter
Features and Functions
The ICT 725 Invisible
®
pet containment sys-
tem is designed for systems up to 3,000 feet of loop
wire and up to 150 feet of twisted pair.
The ICT 725 has a green LED to indicate that
power is on and there is no break in the loop wire.
This LED is ON for 1 second and then OFF for 4
seconds. The LED turns red when the transmitter is
in battery backup mode. The ICT 725 has both an
audible and visual BreakAlert
®
. Should a break
occur in the loop wire, the green/red LED will stay
on without blinking and the BreakAlert will sound
an alarm. This alarm will continue until the break is
repaired, or the unit is turned OFF; disconnected
from the 12v AC transformer. The ICT 725 also has
a course and a fine signal field adjustment knob,
and a switch that changes the channel of operation
between 10k, the UP position and 7k, the DOWN
position.
Lightning and surge protection is provided by
an LP Card that is plugged into the right side of the
circuit board. The signal from the transmitter must
pass through the LP Card to the signal loop wire. If
the LP Card is damaged or removed from the circuit
board the LED will stay on without blinking and the
BreakAlert will sound as previously described.
Another feature of the ICT 725 is internal bat-
tery backup circuitry, that will charge an external
12v battery. With a charged 12v battery the ICT 725
will power the loop if AC electric power is lost.
Removing the ICT 725 Cover
To remove the cover on the transmitter,
hold the base cover of the transmitter in one
hand and, using the thumb and index finger of
your other hand, gently compress the top and
bottom of the top cover plate and remove it.
