• In addition to the internal magnet sensor you can attach
several external sensors to the door/window detec-
tor, such as when you have a wide window bank with
several windows/doors.
These must be NC contacts (normally closed), which
must use the ‘KL2’ connection. See page 31, figure
23.
When connecting several external NC contacts, they
must be connected in series (figure 20).
Do not connect terminating resistors!
• To complete the monitoring, NO contacts (normally
open) can also be used on the door/window detector
(use connection ‘KL1’, see page 31, figure 23).
They must have a potential-free/currentless switch-
ing output.
When connecting several NO contacts, they must be
connected in parallel (figure 21).
Do not connect terminating resistors here either!
Please note:
The ‘KL1’ connection for NO contacts is always active, irrespective of whether
‘disarmed’, ‘internally armed’ or ‘externally armed’ is set. This is ideal, if glass break
sensors with NO contacts are used. An alarm is set off immediately when a pane
of glass is smashed!
• The maximum attainable wiring length per alarm loop greatly depends on the cable used and
the transmission resistance of the magnet and/or glass break sensors. Under ideal circum-
stances 100m or more is possible.
• The wireless range may be reduced when you install the door/window detector and magnet
on metal doors or windows.
• As a rule, the magnet is mounted to the moving part (window, door panel, picture, for example)
and the ‘FAZ 3000-TF-2’ door/window detector is attached to the static part (window frame,
door frame or wall, for example). Please observe the recommended distances between the
magnet and the door/window contact that are illustrated in figure 19 on the previous page.
• The magnet and the ‘FAZ 3000-TF-2’ door/window detector can be attached using the enclosed
double-sided tape.
You can use suitable screws to mount both components to the surface and thus
prevent them from being sabotaged. However, you should first check that they are
working properly so as to avoid drilling any unattractive holes in the ‘wrong’ location.
