If two buttons are connected to the same
detachable terminals, the DC100 will chime the
same for the two buttons. It also may not provide
enough power for lighted buttons.
Do not terminate or connect unused detachable
terminal connections.
Connecting the DC100 to the amp or
controller
If the Source 4 input on the controller or
controller amp is not being used skip the rest of
this paragraph. If you are still reading this, then
connect the stereo source input planned for Source
4 to the “In” RCA jacks on the DC100 chime module.
Next connect the DC100 “Out” RCA jacks to the
controller or controller-amp Source 4 inputs using a
gold stereo RCA wire.
If this installation has more than one controller
and/or controller-amp use good quality Y cords to
connect each of the controller Source 4 jacks (in
parallel) to the DC100 stereo jacks labeled out.
Next connect the DC100 data port to the
controller or controller-amp data port using the
supplied 3.5mm stereo jack/cable.
DC100 Power
Using the provided PS1202 power supply connect
the power supply to the DC100 and plug the power
supply into full time unswitched power. If the
power is switched off then the door chimes will not
work!
Setting the gain.
The controller or amp-controller should be fully
installed with speakers to test it and set the gain.
We suggest that the DC100 gain be turned down
before testing the door chimes.
Turn the controller or controller amp on to standby
and any extra amps connected into the system.
Have someone push the door button and listen to
the level. Adjust it as desired. Some
experimentation with the chime sounds may be in
order. Most of our dealers feel the ding dong (low
tone) chime sound is the best to start with. After
adjusting the level it is important to check all of
the other zones to hear if they are being
overloaded by the chime sound. If they are, then
the DC100 gain (of the whole system) has to be
lowered.
Operation
The system operation should be quite
straightforward.
Press the door chime button and the chime is
sounded throughout the system.
When activated by pressing any of the three door
buttons, the DC100 sends a digital signal to the amp
or controller to turn on or “override” all zones to a
preset volume then runs the chime sound at a gain
set by the installer.
After the door chime sound ends, all zones revert
to their previous volume and input states.
Occasionally the system may become confused if a
door chime was pressed while something else was
going on in the command system of the controller or
amplifier controller. In this case just change the
input or shut the system down as desired from any
keypad. If this does not work turn the power off
then on to the controller or controller amp and the
system will reset.
DC100 size is 143x83x45mm (5.6"x3.25"x1.75").
