Alarm fault detector
-
NSM 1+
If you are using an NR-Line 230, the alarm fault detector handles the prescribed monitoring of the battery buffer in our OPS.
The fault messages "Low battery" or "Power supply restored" can be transmitted to a Telegärtner control centre or to a normal telephone. The functioning of the telephone cable and alarm fault detector can be checked regularly using a programmable timer function.
Tip: The NSM occupies one extension on the NR-Line, which means that only 5 extensions can be connected instead of the normal 6.
