The FAH‑440 Analog Heat Detector is an open-area fire
detector that works with the FPA‑1000 Analog
Addressable Fire Panels. Use it with the FAA‑440
family of bases in indoor dry environments with high
ambient temperatures where smoke detectors might
not be suitable because of steam or fumes; such as
kitchens, boiler rooms, or drying rooms.

Notice

The FAH-440 Analog Heat Detector is not a life
safety device.

Functions

Address Range

The detector has a valid address range from 1 to 254
which is set by rotary switches on the back of the
detector.

Indicator LED

The detector head has a multi‑color LED to indicate
status. To verify power to the detector and functioning
communication of the analog addressable loop, the
LED indicator flashes green when operating normally
(polling). Through panel parameter setting, it is

possible to turn on or off operation of the polling
indicator. In the event of an alarm condition, the
detector LED will always show a steady red light.

Modular Construction

The detector is part of a two‑piece modular design for
detector assemblies. A detector attaches to a base in
the FAA‑440 Analog Standard Base or Analog Isolator
Base family. The base’s security locking tab prevents
any unauthorized detector removal from the base.

Programming

Local programming is carried out at the panel keypad
or by computer through a Web browser. Remote
programming is carried out through a Web browser.

Selectable Threshold Setting

The detector has an alarm threshold temperature
range of +135°F to +194°F (+57°C to +90°C) with 17
possible settings. The rate-of-rise feature can be
switched on or off.

Mounting Considerations

Detectors are typically mounted on the ceiling.
However, if detectors are mounted on a wall, they
must be at least 4 in. (10.2 cm), but no more than
12 in. (30.5 cm), below the ceiling. When other
devices containing magnets or producing magnetic
fields (for example, loudspeakers) are present in the
area, the base must be at least 1 ft (30 cm) from these
devices to prevent unwanted activation of the test
switch.

For UL Listing requirements, the spacing between heat
detectors should be no more than 50 ft (15.24 m).

Wiring Considerations

The control panel communicates to the detectors via
the analog addressable loop (SLC), which allows the
use of standard non‑twisted, non‑shielded wiring.
The following wire gauges were tested and approved:

Wire Gauge Maximum length

18 AWG (ISO 0.75 mm2) 4000 ft (1200 m)

16 AWG (ISO 1.5 mm2) 6225 ft (1900 m)

14 AWG (ISO 2.5 mm2) 7200 ft (2200 m)

12 AWG (ISO 4 mm2) 9850 ft (3000 m)

Remote Indicator

If a remote indicator is used in the circuit, it must be
no more than 10 ft (3 m) from the base.
