Fire Alarm Systems | F220‑B6RS 24 VDC Four‑wire Detector Base with Sounder  
F220‑B6RS 24 VDC Four‑wire Detector  
Base with Sounder  
Easy installation  
Interchangeable detector heads  
UL listed when used with F220 Series Detector Heads  
UL464 approved sounder driven by the detector head  
or the NAC circuit  
2. Reverse Polarity Configuration: In this configuration  
(not suitable for synchronized protocols; such as,  
Cooper Wheelock, Gentex, or System Sensor), the  
sounders in a loop activate due to reversed polarity on  
the power line. The output pattern is not controlled by  
the base in this operating mode; it follows the reversing  
power signal on the detector head's terminals as  
programmed at the control panel.  
The F220‑B6RS 24 VDC Four-wire Detector Base with  
Sounder meets the requirements of UL464 for a notification  
device and works with the F220 Series Photoelectric Smoke  
and Heat Detectors. Power the sounder from the control  
panel's NAC circuit or from auxiliary power.  
3. Local Annunciation Configuration: In this  
configuration, each sounder is individually set for one  
of the following patterns: Temporal (Code 3), March  
Time, or Continuous Tone. Use a D275 Power  
Supervision Module in this configuration to supervise  
the detector loop.  
4. Interconnection Configuration: In this configuration,  
up to five detectors supervise the end of the detector  
loop when interconnected by a common wire. All  
sounders within the group activate together. Set all  
units for the same output pattern (Temporal [Code 3],  
March Time, or Continuous Tone). All interconnected  
detectors are synchronized with and sound the pattern  
of the originating detector.  
Functions  
Sounder Configuration  
The output (sound pattern and synchronization) of the  
sounders on a detection loop can be configured in four  
different ways. Refer to the F220 Series Detectors  
Installation Instructions (P/N: 4998138694) for instructions  
on wiring and setting the F220‑B6RS detector base for  
these configurations:  
1. NAC Follower (Direct Wire) Configuration: In this  
configuration, the sounders on the loop follow the  
signal on the NAC terminals as programmed at the  
control panel. Refer to the control panel's installation  
manual for NAC configuration instructions. This  
configuration requires an extra pair of supervised wires  
for the sounder circuit.  
The maximum wire length for connecting up to five units  
is:  
Wire Size  
Wire Length  
18 AWG (1.2 mm)  
16 AWG (1.5 mm)  
14 AWG (1.8 mm)  
300 ft (91 m)  
450 ft (137 m)  
750 ft (229 m)  
Note  
To ensure interconnected units can signal an  
alarm, the line load after the last detector on
