12.2.1 Magnetic reed contact
12.2.2 Lock bolt
switching contact
L240/BS
A magnetic reed contact is connected in a 4-wire configuration to the
intrusion circuit "Magnet", and the evaluation of the intrusion circuit must be
activated. The magnetic reed contact is used for opening surveillance of the
door (opened or closed). The intrusion circuit cannot be deactivated and
is active when the Intrusion Alarm Panel is set.
The required end of line resistor (2.7 kOhm) is already integrated into
Evaluation Module L240/BS.
Two adjacent wires are connected to terminals "19" and "20" (intrusion
circuit), the two other adjacent wires are connected to terminals "21" and
"22" (end of line resistor).
Magnetic reed contact
If a magnetic reed contact is not connected, the evaluation of the intrusion
detector circuit is off.
A lock bolt switching contact is connected in a 2-wire configuration to the
lock monitoring circuit "Lock", and the evaluation of the intrusion circuit must
be activated. The lock bolt switching contact is used for monitoring the lock
bolt switching contact on the door (bolt extended and door closed). Only the
normally open (N/O) contact is connected.
