Compact KNX security solution for detecting and reporting attempted break-ins, robberies and technical faults. The device has 4 monitored inputs and 3 relay outputs. A 12 V DC SELV auxiliary voltage is required.
The security terminal MT/S 4.12.2M is used as an interface
between security technology sensors and the KNX. The device has
4 inputs, so-called detector groups. They are used for the monitored connection
of passive detectors (e.g. magnetic contacts and/or glass break sensors)
to ABB i-bus® KNX and/or for the connection of potential-free contacts
in applications with increased safety requirements. The device can be used as a system
with independent alarm logic or in combination with the security module
or an intrusion detection system with KNX interface.
Functions of the application program:
-Monitoring 12 V DC auxiliary power supply
-Direct and delayed arming
-Internal (presence) and external (absence) arming
-Detector types (interior, exterior, hold-up, sabotage detectors,
technical detectors, locking detectors)
-Reset input and arming input
-Detector monitoring (closed-circuit, open-circuit principle,
primary line with 2.7 kOhm terminating resistor,
arming line with sabotage monitoring)
-Detector groups can be switched off
-Alarm types (burglary, hold-up, sabotage alarm, Technical alarm)
-Freely programmable relay outputs
