• expander CLK connected to control panel CLK4
• jumpers C1 & C2 in lower position
• expander address programmed as fourth keypad address in the control
panel
• expander zones Z1 & Z2 available as system zones 15 & 16.
Where the expander is installed at a large distance from the control panel (a few
tens of meters), the power supply and ground of detectors connected to the
expander zones should be connected to the control panel with separate wires.
The LCD keypads can only interface in the alarm system with the expander
version manufactured since February 1998.
Connection of Detectors
The CA-10 plus can operate with any type of detectors. Each zone of the control
panel can work in the configuration:
• NC (normally closed),
• NO (normally open),
• EOL (one-parameter),
• 2EOL/NO (two-parameter, NO type detector),
• 2EOL/NC (two-parameter, NC type detector).
When the zone works in a one-parameter configuration (EOL), a 2.2 kΩ resistor
should be used to make the detector circuit.
With two-parameter inputs (2EOL), the detector circuit is closed by two 1.1 kΩ
resistors. The zones of 2EOL type enable the status of detector and its anti-
tampering contact to be monitored at the same time.
The detectors may be power supplied from any of the electronically protected
outputs (OUT1 to OUT4). The output should be programmed as the "POWER
SUPPLY OUTPUT". Detectors connected to the keypad zones can be power
supplied from the +KPD output, however, care must be taken so that the permissible
load of 1.5A is not exceeded for that output.
Figure 6 shows how the detectors are
connected to the two-parameter
configuration zone inputs. Separation of
the detector power supply ground and
the line ground makes it possible to
eliminate the harmful effect of wiring
resistance. Assuming that the wire is
rather short, and only one detector is
connected to it, the installation can be
simplified by using one wire for the
power supply ground (GND) and the
signaling ground (COM).

- Connection of 2EOL detector.
The NO and NC detectors in two-parameter configuration are connected in the same
way, it is only important to correctly indicate to the control panel, what type of
detector is connected to the zone input (2EOL/NO or 2EOL/NC).
