B&K CT600 - Manual (Page 20)

POWER SUPPLY IS CURRENT LIMITED TO 1 AMP PER EVERY THREE ZONES
The six zone receiver has two zone/controller cards, each is identical to the single controller card in a three
zone receiver. Each card has its own independent 1 amp power supply with built in current limiting protection.
You cannot draw more than 1 amp from each of the cards (a card is the vertical strip of zone and common
control connections). The control outputs are current limited to 200mA.
CT310/300 has one power supply card for keypads, IR sensors and 12VDC control outs. Anything connected
to the +12V zone keypad output, a zone control out or a common control out must have its power consump-
tion noted and added up. The total must not draw more than 1 amp for a CT310/300.

Adding Additional Keypads in the Same Zone.
When rooms are interconnected or are open to each other (for example: interconnecting family room, kitchen,
and dining areas are common in many homes) you may opt to expand a zone to include several rooms.
Many keypads can be connected in a daisy chain from the master keypad in that zone. The master is the
keypad which is home run back to the CT Receiver. To daisy chain keypads, simply connect a CAT5 cable
terminated into RJ-45 between the two keypads. All the chained keypads need be programmed separately .
Daisy-chained keypads can be programmed for independent zone control using the appropriate code-set.
The home run (master) keypad is connected using the MASTER [IN] on the keypad back panel. From the
Master Keypad's SLAVE[OUT] connect to the second keypad's MASTER [IN]. You can continue the daisy-
chain to as many as four keypads per zone control terminal. When programming daisy chained keypads,
each keypad must be programmed separately. Always program chained keypads in series order start-
ing with the Master keypad, then the first slave, etc.
