The six zone CT Receiver 12VDC outputs support a maximum of 20
keypads total, ten keypads to each vertical array of three zone control
connections. Thus, a three zone CT Reciever can support a maximum
of 10 keypads. If power is being supplied to relays, screens or sensors,
these devices must be accounted for and would reduce the total num-
ber of potential keypads.
Each CK 2.2 keypad consumes 75mA.
Terminate the RJ-45’s using any color code, just connect the cables
straight through, i.e. exactly the same color to pin on each end of the
cable. Standard pre-terminated LAN (Local Area Network) cables work
fine.
For convenience, the T568-B color scheme is listed and shown below. N/C is Not Connected.
Each of the zone/control cards of the CT600.3 are indentical to the single card of the CT
300.3. Zone/Control cards incorporate 3 zone keypad/sensor connectors and 1 common
control output. The total power consumption of all devices attached to one card
cannot exceed 1 amp
.
