POWER SUPPLY IS CURRENT LIMITED TO 1 AMP PER EVERY THREE ZONES
The six zone receivers have 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.
It is not allowed to draw more than 1 amp from each of the cards (a card is the vertical strip of zone and com-
mon control connections). The control outputs are current limited to 200mA.
The CT 300.3 has one power supply card for keypads, IR sensors and 12VDC control outs. Anything con-
nected to the +12V zone keypad output, a zone control out or a common control out must have its power
consumption noted and added up. The total must not draw more than 1 amp for a CT 300.3.

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 may 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 straight
through CAT-5 cable terminated into RJ-45 between the two keypads. All the chained keypads need be pro-
grammed separately . Daisy-chained keypads may 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 may 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. Do not program a slaved keypad while it is physically
connected to the master keypad.
