Partition keypad
CA-64 S SATEL
MODULE INSTALLATION AND STARTING
The schematic view of part of the board with cable terminals is shown in Figure 2.
The set of switches on the board is used for setting the individual module address.
If the door status monitoring input IN is not used, connect it to ground.
Two NO relay terminals are used for controlling the door electromagnetic lock.
The microswitch, located at the keypad board, is used as anti-tampering protection. When the
module is installed correctly, the spring on the microswitch should be pressed against the wall.
MODULE TERMINALS:
NO
- relay terminal
IN
- door status monitoring input (NC)
COM
- ground
+12V
- power supply input
DTA, CLK - expander bus

INSTALLATION
The partition keypad module may be mounted either directly to the wall or in the OBU-M-LED
metallic casing. This casing is closed with a key, which makes access of unauthorised persons
to the keypad more difficult.
MODULE WIRING
NOTE: Disconnect power supply for the whole system before you start to wire the module
to the existing alarm system.
1. Remove the plastic module casing by pressing the clips, which fix the casing bottom.
2. Fix the bottom of plastic casing to the wall. The connecting leads should be passed through
the rectangular opening in this part of casing.
3.
Connect the leads of first or second expander bus to the following terminals: DTA, CLK and
COM (first bus: CK1, DT1, COM; second bus: CK2, DT2, COM –as marked at the control
panel main board). As many as 32 modules of different types may be connected to one
single bus.
4. Set the expander address by means of switches.
The module address is set with switches numbered from 1 to 5. The remaining switches
(6, 7, 8) are irrelevant. In order to define the expander address, summarise numbers
corresponding to switches set to position ON, according to the table:
Switch
number
1 2 3 4 5
Corresponding number
1 2 4 8 16
Examples of addressing:
address
= 4
address
=2+8=10
address =1+8+16=25
These five switches allow to address 32 expanders (numbers from 0 to 31). The
addresses of expanders connected to one, common bus must be unique, and the order of
1 2 3
4 5 6
7 8
ON
ADDRESS
NO NO IN COM+12V DTA CLK
1 2 3 4 5 6 7 8
1 2 3 4 5 6 7 8
