−
relay output: LED is ON – terminal NO is shorted to common terminal C, and terminal
NC is disconnected from common terminal C;
−
relay output: LED is OFF – terminal NO is disconnected from common terminal C,
and terminal NC is shorted to common terminal C.
4 - relays – all relays are only installed in the CA-64 O-R version. In the CA-64 O-ROC
version, the relays are installed for outputs from 5 to 8.
Description of the terminals:
C1...C8
- common relay terminal or OC type output;
NO1...NO8
- terminal normally disconnected from the common relay terminal. When in
active state or in case of reversed polarization, it is shorted to the common
terminal.
NC1...NC8
- terminal normally shorted to the common relay terminal. When in active state
or in case of reversed polarization, it is disconnected from the common
terminal.
AUX
- power supply output (+12V DC).
COM
- common
ground.
TMP
- tamper input (if no tamper contact is connected to this terminal, it should be
shorted to common ground).
CLK
- clock.
DTA
- data.
+12V
- power supply input.
The RESET
pins are used during the manufacturing process, hence they must not be
shorted.
1.1 DIP-switches
The DIP-switches from 1 to 5 are to be used for address setting. The address must be
different from that of the other modules connected to the communication bus of alarm control
panel. In order to determine the expander address, add up the values set on individual
switches as shown in Table 1.
