tional Detector Bases
Features
▶ Easy installation
▶ Interchangeable detector heads
▶ UL listed when used with an F220 Series detector
The F220‑B6 Series Detector Bases work with the F220
Series Photoelectric Smoke and Heat Detectors. The
F220‑B6 is a 12 V or 24 V base for two‑wire loops. The other
bases in this series are 12 V or 24 V bases for four‑wire
loops.

Installation/Configuration Notes
Compatibility Information
Two‑wire:
 Bosch Security Systems, Inc. makes no claim
written, oral, or implied that the F220‑B6 Series Detector
Bases work with any two‑wire control panels except those
specified in the Two-wire Detector/Control Panel
Compatibility List Technical Service Note
(P/N: 4998148185).
Four‑wire: Compatible with all UL Listed four‑wire control
panels. Refer to the control panel's Installation Instructions
for proper end‑of‑line (EOL) resistor selection.
Detectors: Compatible with the following F220 Series
Detector Heads:
F220‑P Photoelectric Smoke Detector
F220‑PTH Photoelectric Smoke Detector with +135°F
(+57°C) Heat Sensor
F220‑PTHC

 The F220‑PTHC detects carbon monoxide (CO) as a
component of a fire. It is not a CO detector and cannot
activate an alarm in the presence of CO only.
Mounting Considerations
Depending on local regulations, surface mount the bases
using anchors, mollies, or wing nuts; or mount the bases
directly on four‑inch square or octagonal electrical boxes or
single‑gang switch boxes.
Note
The electrical box must be large enough to
accommodate the number and size of
conductors specified by the National Electrical
Code or any local authorities having
jurisdiction (AHJ).
Wiring Considerations
In a two‑wire system, the maximum loop length depends on
the number of F220‑B6 bases on the loop, the wire size, and
the control panel specifications. Refer to the control panel's
installation instructions for specific wiring information.
In a four‑wire system, the maximum loop length and number
of bases that can be placed on a loop depend on the voltage
drop on the power circuit. Use standard voltage drop
calculations to ensure that the last detector on the loop has
at least 10 V.
