Tamper reset circuit “11=Eng Rst”
VdS
Tamper reset circuit “11=Eng Rst”
VdS
A brief interrupt of this group (e.g. with a key switch) causes the stored
alarms (e.g. internal, intrusion or personal attack alarms) to be deleted
including a tampering alarm.
Internal set circuit
“12=Int Set”
Internal set circuit “12=Int Set”
An internal set circuit switches the area internally set/unset. It is
programmable for button mode (pulse on) or switch mode (pulse off).
For button mode (recommended), touch contacts can be connected and with
every transition from interrupted to non-operation (terminated with 2.7
kOhm) switch over occurs. In switch mode, an interrupted circuit
corresponds with internal set and a non-operational circuit (terminated with
2.7 kOhm) is unset.
User code circuit
“13=Log On”
User code circuit “13=Log On”
A brief interruption of this group (e.g. with a key switch) has the same effect
as the entry of a valid 4-digit user PIN on Keypad L240/PT. Access to the
user level (access level 1) is enabled. The activation of this user code circuit
is stored in the event log as “Code-Cct on”.
External set circuit “14=Ext Set”
External set circuit “14=Ext Set”
An external set circuit switches the area externally set/unset. It should be
programmed for switch mode (pulse off) (button mode not supported). This
option applies for the circuit inputs on the main circuit board.
Conventional setting (arming) contacts can be connected.
In switch mode, the circuit is terminated in the unset state with a 2.7 kOhm
resistor. For setting purposes, a 560 Ohm resistor is switched in series to the
2.7 kOhm resistor (= 3.26 kOhm). In this way not only the set/unset states
but also the short circuit/open circuit states are monitored.
An interrupted circuit (except 2.7 kOhm or 3.26 kOhm) causes a “Tamper
setting” alarm.

1=Standard
; 2=EIB/KNX
The selection
Standard
ensures no access from the KNX to the circuit. The
L240 “wired” circuit is evaluated.
The selection
EIB/KNX
enables access from the KNX to the circuit, i.e. only
the KNX circuit is evaluated, the L240 “wired” circuit is
not
evaluated.
