The SIMATRIX NEO V2 is able to process alarm sensors signals, which can be
configured as normally closed or normally open contacts.
The schematic below shows how to connect alarm sensor contacts:
Fig. 15 Connecting a detection group to Alarm 1 - 16/ TTY out
The detection group must be no further than 10 m distant from the SIMATRIX
NEO. If the distance is greater than this, relays should be inserted in the circuit.
The "SysLink" socket allows connection of an extension bay and an alarm box via
the serial bus.
