Connect the spade quick-connect
on the BLACK wire to the negative
(-) terminal on the 12v battery.
Caution: Be careful not to reverse
the RED and BLACK wires when
you connect them to the terminals on the bat-
tery. The RED wire is po) and
the BLACK wire is negative(--).
Slide the
battery into the
battery box.
The bottom of
the battery
should sit on
the internal
reinforcing ribs
on the bottom
of the box.
When the
battery is in the battery box,
cinch the zip tie tightly
around the battery to hold the
battery securely in the box.
Use 4, 3/4 inch(19mm),
#10 pan-head sheet metal
screws to fasten the battery
box to the wall.
After the battery box has
been fastened to the wall,
connect the battery to
the transmitter’s
circuit board.
Finish the installation
by feeding any loose wire
between the transmitter
and the battery box into the
hole on the back edge of
the battery box.
ICT 775 transmitters have a two position header-
connector that the plug holding the two leads from the
battery is plugged into. The rectangular connector has
two metal prongs and is labeled -- BATT +. It is
located on the bottom, left of the transmitter’s circuit
board between the LED and the 12vAC Power Jack.
The battery connector is designed so that the plug
that holds the two inboard ends of the wires that are
connected to the battery will only go into it one way,
making it nearly impos-
sible to reverse the bat-
tery wire connections
at the transmitter.
There is a replaceable, 2amp fast-blow fuse on
the bottom left side of the transmitter’s circuit board
to protect the transmitter and the battery. If the wires
are accidentally crossed when they are connected to
the battery, or if the plug is connected to the transmit-
ter incorrectly, the fuse will blow.
Batteries Recommended by Invisible Technologies,
Inc., are all 12vDC, 5.0Amp hours.
Warning: Only use one of the
approved lead-acid batteries.
Using a battery that is not lead-acid, or
a battery with a different voltage can damage
both the transmitter and the battery.
Note: The recommended 12vDC
lead-acid batteries have a five year
shelf life, and should be replaced,
whether they have been engaged often or not,
after that time.
Detecting Low Voltage in the Backup Battery
After a 12v battery is fully charged, a micro-
processor in the transmitter will automatically check
the battery’s voltage. If the voltage of the battery
