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

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.

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.

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.

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.

The maximum wire length for connecting up to five units is:

Wire Size

Wire Length

18 AWG (1.2 mm)

300 ft (91 m)

16 AWG (1.5 mm)

450 ft (137 m)

14 AWG (1.8 mm)

750 ft (229 m)

Note To ensure interconnected units can signal an alarm, the line load after the last detector on
