12.5.1 Function switch 1

12.5.2 Function switch 2
L240/BS
The following settings and parameters can be undertaken with function
switch 1:
Function switch 1-1 "Connection of 0 V potential bolt lock-XIB":
Function switch 1-1 can establish potential equalization between the minus
of the bolt lock voltage supply (terminal 16) and the minus of the XIB security
bus (terminal 4).
As there is a separate voltage supply for the lock bolt and the XIB bus,
differing cable lengths and current loading can result in potential shifts.
Note: The power supply for the bolt lock must be provided from the
same Intrusion Alarm Panel as the XIB bus.
OFF: No connection between the 0 V potential from the bolt lock and the
XIB bus (standard)
ON: A connection and thus the same potential between the 0 V potential
from the bolt lock and XIB bus
Function switch 1-2:
Must be "OFF".
Function switch 1-3 "free":
Function switch 1-3 has no function and must be set to OFF.
Function switch 1-4 "Send High/Low":
Must be "OFF".
Function switch 1-5 "Test wireless communication":
Must be "OFF".
The following settings and parameters can be undertaken with function
switch 2:
Functions switch 2-1 "Sabo resistor"
Using function switch 2-1, the end of line resistor (2.7 kOhm) for the
tampering circuit (terminals 7-8) in the evaluation module can be bypassed.
OFF: The end of line resistor in the evaluation module is looped in. Only
the cover tamper contact (N/O contact) in the SafeKey Wall Reader and
no end of line resistor is required (standard).
ON: The end of line resistor in the evaluation module is bypassed. Only
the cover tamper contact (N/O contact) in the SafeKey Wall Reader and
an end of line resistor (2.7 kOhm) are required.
Function switch 2-2 "free":
Function switch 2-2 has no function and must be set to OFF.
