u Two-wire or four-wire bases
u 50 ft (15.2 m) maximum spacing between detectors
u Visible identification of model: F220‑135 = no ring,
F220‑135F = gray ring, F220‑190F = black ring
The F220 Heat Detectors include:
• F220‑135: An electronic rate-of-rise, fixed
temperature heat detector that initiates an alarm
when the ambient temperature exceeds +135°F
(+57°C) or when the ambient temperature increases
by +15°F (+8.3°C) or more in less than 1 minute
• F220‑135F: An electronic fixed temperature heat
detector that initiates an alarm when the ambient
temperature reaches +135°F (+57°C).
• F220‑190F: An electronic fixed temperature heat
detector that initiates an alarm when the ambient
temperature reaches +190°F (+88°C).
The detectors use low current electronic circuitry, so
they can connect to 12 VDC nominal or 24 VDC
nominal power source circuits. When mounted on the
appropriate F220‑B6 Series Mounting Base, the F220
Heat Detectors provide general property protection
from fire.
Notice
Heat detectors are not life safety devices.

Functions
Compatible Bases
Configure the detectors as either two-wire or four-wire
depending on the mounting base selected. These
detectors are compatible with any of the F220‑B6
bases:
• F220‑B6 12/24 VDC Two-wire Mounting Base
• F220‑B6R Standard 12/24 VDC Four-wire Mounting
Base
• F220‑B6RS 24 VDC Four-wire Mounting Base with
Sounder
• F220‑B6C 12/24 VDC Four-wire Mounting Base with
Auxiliary Form C Relay
• F220‑B6E 12/24 VDC Four-wire Power Supervision
Mounting Base
• F220‑B6PM 24 VDC Four-wire Addressable Master
Base
• F220‑B6PS 12/24 VDC Four-wire Addressable Base
Dual-color LED
To verify the detector has power and the heat
detection circuitry functions, a dual-color LED
indicator flashes green every 8 sec when operating
normally. It flashes once every 4 sec when a trouble
condition exists. The LED latches on red if an alarm

occurs, allowing the user to easily verify individual
detector alarms. Clear the alarm condition by
interrupting power to the detector.
Tamper Detection
When detector heads are correctly installed in any of
the F220‑B6 bases, the control panel initiates a
trouble signal if a detector is removed from its base. A
mechanical tamper lock comes with each base to
inhibit unauthorized head removal.
Supervision
The control panel supervises two-wire systems.
Supervision of four-wire system power is provided by
an end-of-line (EOL) power supervision device such as
a D275 or PAM-4, or an F220‑B6E Power Supervision
Mounting Base and an EOL resistor as specified by the
control panel manufacturer.

Installation/configuration notes
Compatible Control Panels
Addressable Systems: These detectors are compatible
with addressable systems controlled by D9412GV2,
D7412GV2, D9412G, or D7412G Control Panels or the
D9124 Fire Alarm Control Panel when used with the
F220‑B6PM or F220‑B6PS Addressable Detector
Bases.
Two-wire: Bosch Security Systems, Inc. makes no
claim written, oral, or implied that these detectors
work with any two-wire control panels except those
specified in the Control Panel Compatibility chart in
the Technical Service Note (P/N: 4998148185).
Four-wire: Thes detectors are compatible with all UL
Listed four‑wire control panels. For proper end-of-line
(EOL) resistor selection, see the control panel's
installation instructions.
Mounting the Bases
Depending on local regulations, the bases can be
surface mounted directly on four-inch square or
octagonal electrical boxes and single-gang switch
boxes.
Notice
The volume of any electrical box used should be
adequate to accommodate the number and size of
conductors as specified by the National Electrical
Code or any local authorities having jurisdiction
(AHJ).
End-of-Line Power Supervision
Loop supervision requires one D275 or PAM-4 or
F220‑B6E per loop when using F220‑B6R/B6C bases
and is accomplished by the control panel.
Wiring the Bases
For detailed wiring instructions, see the F220 Series
Detectors with F220‑B6/C/E/R Bases Installation
Instructions, the F220 Series Detectors with
F220‑B6RS Bases Installation Instructions, or the
F220‑B6PS/M Installation Instructions.
