Keypad Connections
Keypads connect to the CT Receiver at the Zone Control I/O Terminals. Termination of the Keypad cables to
the Control Terminals is done by a straight through CAT-5 cable.
CK1.2 Keypad Connections
Each of the 5 functions for the keypad control ports are defined as follows:
+12VDC - Use this terminal to power the sensors and keypads for this zone. Each control card is limited to 1 amp capacity per three
zones in each vertical array. See the next page for examples.
GND - Use this terminal as a common ground for data, control and power.
RS-232 XMIT - This terminal transmits RS-232 information. This pin allows RS-232 status feedback to the CK1.2 keypad or other RS-
232 capable devices. It may be configured with Tab 11 of BK Suite. The CT Receiver may not receive RS-232 via this terminal.
DATA IN - This terminal is an IR data port feeding both the flasher port of the selected input (unless routing is set to ALL) and the
m a i n CT microprocessor for B & K commands.
CTRL OUT - The 12VDC 200mA outputs are used to control external amplifiers, relays, screens or devices that activate when a volt-
age is detected. The default action is that the voltage is ON when the Zone is ON, OFF when the zone is off. This is controlled by
going into the Advanced FULL Setup Tab 9 in BK Suite. The 12VDC controls may be modified to the following choices:
Zone On The 12V Control Out is on if the corresponding Zone is on (This is Default).
Zone Active The 12V Control Out will turn on only if the Zone is on AND the CT Receiver may
detect an audio or video signal on the selected input for that hardware zone.
Zone Off The 12V Control Out will turn on only if the corresponding hardware Zone is off.
Selected Input The 12V Control Out is on only if this input is selected (switched to) by the user.
Note - when this option is selected, the input check boxes are active. Check all inputs that are desired to
turn on the Zones Control Out.
If needed, the pin out configuration of the keypad wiring is
located on the back of the CT receiver.
