Features
5.1 Configuration
On the sounder base is a four position DIP switch.
Table 9: F220-B6RS Sounder Base Configuration
Position 1 and
2 (separately
controlled
sounder)
switches off
Control panel NAC circuit power is
applied to the base to Terminals 4(+)
and 5(-). The sounder follows the
configuration of the NAC. See the
control panel manual for NAC
configuration.
Positions 1 and
2 switches on
Power is taken from the head to activate
the sounder. Sounder output configured
by DIP Switches 3 and 4.
Position 3 on
Code 3 signal.
Position 4 on
March Time signal.
Positions 3 and
4 off
Steady signal.

5.2 Interconnect
feature
When the sounder is powered from the head, you can
connect up to five detectors by a common wire on
Terminal 3. All sounders within the group activate
together. Set all units for the same sounder type on
Switches 3 and 4, otherwise all detectors sound the
pattern of the originating detector.
To ensure interconnected units can alarm,
the line load after the last detector must not
exceed 10 mA so.
These restrictions do not apply to reverse
polarity activation.
