B&K CT600, CT602, CT310, CT610, CT300 Adding Additional Keypads in the Same Zone, Left Control Card

16 12V Power Supply

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.

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.
