12 INTEGRA 128-WRL SATEL

Terminals:

AC - power supply inputs (18 V AC)

COM - common ground

OUT1...OUT2 - programmable high-current outputs (if not used, they should be loaded

with 2.2 kΩ resistors)

+KPD - dedicated power supply output for devices connected to keypad bus

(13.6...13.8 V DC)

DTM - keypad bus data

CKM - keypad bus clock

+EX - dedicated power supply output for devices connected to expander bus

(13.6...13.8 V DC)

DT - expander bus data

CK - expander bus clock

AUX - power supply output (13.6...13.8 V DC)

Z1...Z8 - zones

OUT3...OUT8 - programmable low-current outputs, OC type

3.5 CONNECTING KEYPADS AND OTHER DEVICES TO KEYPAD BUS

Up to 8 different keypads or other devices to be connected to keypad bus can be installed in

the system. They are connected in parallel. The data are addressable and all devices

function independently.

The keypad bus terminals on control panel mainboard have designations COM, +KPD, DTM

and CKM. The +KPD output enables powering of the keypad bus devices (the output has

a polymer fuse).

The distance between the keypad or other device to be connected to keypad bus and the

control panel may be up to 300 m. Table 1 shows the number of wires required for correct

connection of devices to the keypad bus, if using a 0.5 mm

cross-section straight-through

cable.
