22 Installation Guide CA-10 plus SATEL

The keypads are not be connected in parallel to one CLK signal (one partition - two

keypads), with the exception of the CA-10 KLED keypads. The other LCD keypads

as well as the CA-10 KLED-M and CA-10 KLED-S keypads must not be connected in

parallel.

The keypad anti-tampering contact has no connection with the system anti-tampering

circuit. Its state is defined by the control panel, based on the data received from the

keypad. When the control panel is in the service mode, the anti-tampering contact is

not controlled.

Connection of Zone Expander

In order to increase the number of zones, a zone expander can be connected,

instead of a full set of

keypads. It makes

available the zones of

keypads required for full

configuration. The

expander should be

connected as a next

keypad. It can be used in

combination with a

different number of

keypads.

Figure 5 shows how the

expander is connected to

the CA-10 plus control

panel.

The jumpers A, B, C, D are used for setting the expander address – the upper

position corresponds to a jumper set in the keypad. The jumpers C1 & C2 should be

set as required by the number of keypads connected to the panel. The expander

jumpers must be set in either upper or lower position - they must not be permanently

removed.

The expander TMP input is an equivalent to the keypad tamper – normally it should

be shorted to ground.

The control panel and expander can be configured in three ways:

1 keypad and expander:

• keypad connected as first keypad (CLK1)

• expander CLK connected to control panel CLK2

• jumpers C1 & C2 in upper position

• expander address programmed as second, third and fourth keypad address

in the control panel

• expander zones Z1 to Z6 available as system zones 11 to 16.

2 keypads and expander:

• keypads connected as first and second keypads (CLK1 & CLK2)

• expander CLK connected to control panel CLK3

• jumper C1 in upper position, C2 in lower position

• expander address programmed as third and fourth keypad address in the

control panel

• expander zones Z1 to Z4 available as system zones 13 to 16.

3 keypads and expander:

• keypads connected as first, second and third keypads (CLK1, CLK2 &

CLK3)
