Keypad Total Power Consumption
The CT six zone receiver 12VDC outputs can support a maximum of 20
keypads total. 10 keypads to each vertical array of three zone control con-
nections. Thus, a CT three zone receiver 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 number of poten-
tial keypads. Each CK1.1 keypad consumes 75mA.
Each of the zon e/control cards of the CT610 are identical to the single card of the
CT310. Zone/Control cards incorporate 3 zone keypad/sensor connectors and 1
common control output. The total power consumption of all devices attac hed to one
card cannot exceed one amp.

Mounting
After connections are made, the CK1.1 installs into a standard single gang
J-Box or an open backed single gang trim ring with the screws provided. If
you opt to use a closed J-Box, it must be a minimum of 2 3/4” deep to
accommodate standard RJ-45 plugs in the rear. It is fastest and easiest to
mount the keypad in an open backed trim ring as shown here:
Often the best solution to mounting a B & K keypad are the
mounting plate brackets for Low Voltage Class 2 devices.
Enclosed J-Boxes can be used, they must be deep enough
to accommodate the depth of the RJ-45 connectors
plugged into the rear of the keypad (2 3/4”).
