NOTE:
1.
You can connect external equipment to clamp
N.O
instead of to clamp
N.C
.
If you connect to clamp NC (normally closed), the circuit between the system and an external device is
closed. If the switch output is activated, the system interrupts the circuit and the connected device is
switched off.
If you connect to clamp NO (normally open), the circuit between the system and an external device is
interrupted. If the switch output is activated, the system closes the circuit and the connected device is
switched on.
2.
The “COM/BLK” and “AUX/RED” clamps are collective clamps. You can connect more than one cable to
them.
Connect transistor outputs
UO3
(switch output 3) and
UO4
(switch output 4) as follows:
Connect the positive connector of the external device you want to control with “
AUX /RED
”
(+)
clamp and the negative with the
clamp of the switch output UO3 (or UO4).
5.5.4 Connecting a device ground
The grounding (earth) protects your electronic equipment against damage and interference caused by lightning and inductive
voltages.
An ideal grounding is the earth connection (green/yellow wire) in the power socket.
Important: Never connect 230V directly to the system. Only the earth!
Connecting to ground:
•
Make a connection between the earth contact of the
ABUS wireless alarm system
and an electrical earth connection to
protect it against lightning and static electricity.
!
IMPORTANT NOTE:
The earth contact must be made in accordance with local regulations.
5.5.5 Connecting a wired zone
The
ABUS wireless alarm system
has a wired zone –
Zone 33 (Z33)
, which can be used, for example, to connect a key switch or
a panic emergency call. Connect this zone using twisted-pair cables or a 4-core cable. The following figure shows the different zone
connection types – these have to be programmed accordingly in the installer menu later:
NOTE:
The wired zone cannot be used as a fire zone. For a zone with tamper, you can use a double terminal resistor (DEOL) to
save additional connections.
5.5.6 Connecting an external consumer
Use the collective clamps
AUX/Red (+)
and
COM BLK (-)
, to connect external devices or detectors that require a power supply of
9V DC with a maximum power consumption of 200mA.
!
IMPORTANT:
During a power failure, the AUX output is deactivated to ensure a longer system runtime.
NOTES:
The total current of collective clamps should not exceed 200mA.
If the collective output is overloaded (more than 200 mA) and it is silenced, you have to interrupt the load at the output
for at least 10 seconds before reconnecting a load to the collective output.
