4. The resistors in series with each zone and the common OUT port provides current sharing to each
emitter and also allows the use of dual emitters in combination with single emitters. You may,
therefore, connect any combination of emitter models 282, 283, 284 & 286 series emitter series to the
zone ports and the common OUT port, to control the desired number of components.
5. When using fewer than 10 emitters on the 791-44 (common) emitter ports, you may plug them in
without regard to order, as shown in
Fig. 2
.
6.
Considerations for Shielded Wire and Long Lead Lengths.
When using long lengths (>50 ft.) of
inter-room shielded cable (> 75 ft. unshielded), it may be necessary to connect a 470 Ohm 1/8 Watt
resistor between IR
IN
(signal) and
G
at the 3-screw terminals of the 796-20. Refer to
Fig. 3
.
Please Note:
The zone numbers for the
rooms in
Fig. 2
do
not
agree with the zone
numbers marked on the 796-20. The reason
for this is that the 796-20 is designed to
expand the zones of a 795-20 as shown in
Fig. 4
, in which case the zone numbers do
match.
