The alarm activation sensitivity for radio smoke detectors DOW1171 can be set for
each detector point.
The table below lists the possible parameter sets and the average reaction times
with test gas:
Parameter set no. Parameter set name
1 (Default) No verification
Test, applications that are
not prone to deceptive
phenomena
2 Short verification period
3 Medium verification period
4 Maximum verification period 105
5 Maximum verification
period,
additionally with strong filter
Power supply of the radio gateway is normally ensured via the FDnet detector line.
Short-term power failures (< 5 hours) on the detector line can be bridged by the 9V
battery.
