Multiple Parallel Keypad & Speaker Connections
In some systems, any one room on the Genesis may need to provide audio to several rooms.
Typically, these rooms are common to each other such that it will not present an operation
problem if all common rooms turn on at once. Furthermore, such a room area will have more
than one keypad so that the system can be engaged from any one room. In addition, each room
will most definitely have its own volume control for local volume attenuation.
Example
In a particular home, there are a total of nine rooms yet the Kitchen, Dining Room, Living Room,
and Entry Hall are all open to each other. You can therefore, group these four rooms together
as one "common room". They will connect to only one of the Genesis System's six independent
room outputs. This will leave the remaining five Genesis room outputs open for use with other
rooms. While some of the common four rooms could include only a volume control, all of them
could also include a full keypad with volume control. Please note, that when one room is on,
so are all the other common rooms. You can then lower the volume control to its lowest setting
to eliminate the audio from playing in any one room.
Note
While this option can be repeated for several of the six Genesis room outputs, the overall
impedance level of the Genesis's built in amplifier is 1/2
Ω
. Thus you should connect no more
than 16 pair of 8
Ω
or 8 pair of 4
Ω
speakers to any one Genesis. To determine your speaker
load for the entire home when wiring speakers in parallel, use the following equation.
1/(Room 1's
Ω
) + 1/(Room 2's
Ω
) + ....... + 1/(Room N's
Ω
) = 1/(Total
Ω
)
When using more than one keypad per Genesis Room, ADA recommends running each
keypad's control cable individually home to the system mainframe. This will permit some
flexibility should the client wish to expand the system at some later date and will also provide
for easy troubleshooting should a problem exist with one of the keypad wires. While you can
daisy-chain both control cable and speaker cable, running from the equipment mainframe
(home) to the key-
pads location, with
each sub-room's
speaker cable run
individually to
each room's key-
pad location, run-
ning each sub-
room's control and
speaker cable di-
rectly from the
keypad location to
the mainframe is
the best option.
