5. Connect the DTM, CKM and COM keypad terminals to the appropriate terminals of the
control panel communication bus (Fig. 2). It is recommended that the unshielded
non-twisted cable be used for making the connection. If you use the twisted-pair type of
cable, remember that CKM (clock) and DTM (data) must not be sent through one
twisted-pair cable. The wires must be run in one cable. The length of cables must not
exceed 300 m.
6. If you wish to connect any detectors to the Z1 and Z2 zones, connect the wires to the
terminals (connect the detectors in the same way as to the control panel onboard zones).
7. Connect the supply wires to the KPD and COM terminals. The keypad can be powered
directly from the control panel, from an expander with power supply or from an additional
power supply. The table shows the requirements regarding the power wires (KPD and
COM), if conductors with 0.5 mm diameter are used.

8. Place the front panel onto the catches and snap close the enclosure.

3.1 Description of terminals

KPD - power supply input.
COM - common ground.
DTM - data.
CKM - clock.
Z1, Z2 - zones.
RSA, RSB - terminals provided for future applications (RS-485).

3.2 Address setting

Each keypad connected to the control panel must have its individual address set in it.
By default, address 0 is set in the keypad.
