ABUS 2-Zone alarm system Conrad Alarm zones 2 Conrad 数据表

Alarm zone 1 triggers the alarm 
immediately  in case of alarm. 

Alarm zone 2 triggers the alarm 
with a delay after the end of the entry
delay (= 30 seconds).

Terminal clamp 2 is the joint reference point (-) for both alarm zones.
Connect the sensors with N.C. contacts in sequence, and those with N.O. contacts
in parallel.
If no sensors with N.C contacts are used, a 10kOhm EOL resistor must be integrat-
ed to secure the switching circuit (included in the delivery). 

☞

Alarm zone 2 is best suitable for sensors that are installed in the inside
area (such as motion detectors), since these sensors would trigger
alarm when the house is entered. An alarm is only triggered after the
end of the activation delay (= 30 seconds). The alarm system can be
disarmed in this period (for this, the mode selection switch at the front
must be returned to the “OFF” position).



To ensure proper sensor operation with an N.C. contact it must be
ensured that every sensor with an N.C.contact has a maximum resis-
tance of 1kOhm.
