Connecting The Alarm Centre To The 230 V Mains Supply; Connecting Wired Detectors (Optional) - Abus Secvest 2WAY Installation Instructions Manual

8.6 Connecting the alarm centre to the 230 V mains supply

Connecting the alarm centre to the 230 V AC mains network is subject to national
regulations. Check that no voltage is present in the connection cable when fitting.
Connect the 230 V power supply to the mains connector according to EN60950-1 as
shown in the diagram. Remember to fix the cable with suitable tension relief.
Colour configuration of the lines:
L : Brown or black
: Green/yellow
N : Blue
Always replace the mains fuse with one of the same type. Never use
fuses with higher voltage ratings than those specified.
The green/yellow (earth) wire should be slightly longer than the live
and neutral wires.

8.7 Connecting wired detectors (optional)

If wired components are connected to the wireless alarm, then connect them as
shown in the diagram. Please note that the detectors can only be connected in this
way (DEOL).
Zone closed with a 2.2 kOhm line resistance (two resistors inserted). The 4.7 kOhm
resistor is also inserted, but is bypassed by the alarm contact of the detector (see
illustration).
In this variation, the tamper contact and alarm contact are monitored in one zone. In
the event of a change of resistance, the alarm centre can distinguish whether the
cause is an alarm or tamper attempt. Note that there are two different resistance
values:
A: 2.2 kOhm (red, red, red, gold)
B: 4.7 kOhm (yellow, violet, red, gold)
