A) INSTALLATION WITH A TRANSFORMER
Follow the wiring diagram on the backplate. If your existing
doorbell has two wires, install one wire to the “F” terminal and
the other wire to the “T” terminal. To test, slide the iChime
product onto the backplate and press the doorbell button.
If you have a backdoor button, follow the wiring diagram. In
this case there will be three wires to connect: “F” “T” and “B”.
If batteries are installed in iChime, you are done!
Since so little power is required to operate
iChime, the batteries will last for quite a long time. However, iChime can be exclusively powered
by a transformer, In this case it is necessary to install a diode across the exterior pushbutton (at
the front door). Even with AC power from a transformer, batteries can also be installed so that the
chime will operate when it is removed from the wall mounting bracket.
A typical diode (part number 1N4001) is pictured to the left, and is about
1/4" long with wires coming out of each end. The diode allows power to
be supplied to iChime. A diode can be supplied for free with your
purchase. The easiest way to install the diode is across the pushbutton
terminals.
The diode needs to be installed on the back of the pushbutton out by the front
door, as shown on the picture to the right. The diode is marked with a band on
one side. The banded side of the diode has to be connected to the wire leading
to the “F” terminal. If it is not possible to determine which wire goes to the “F”
terminal it is OK to guess and test to see if the operation is as expected.
Installing the diode backwards will not damage the chime or the diode. To install
the diode, remove the front doorbell pushbutton from the wall, loosen the two
screw terminals and wrap the wires from the diode around each one. Be careful
to not let the wires on the diode touch any exposed metal parts. Then tighten
the screw terminals and test the operation. After confirmation, reinstall the
pushbutton to the wall.
