u Dual Ray Technology provides better particle size

differentiation resulting in fewer false alarms

u Smoke threshold is adjustable and automatically

compensated

The FAP‑440 Dual Ray Detectors are open-area smoke
detectors of which some models are enhanced with
heat or heat and CO sensors. These detectors work
with the FPA‑1000 Analog Addressable Fire Panels.
Use the detector with the FAA‑440 bases to provide
general life safety and property protection.

Functions

Address Range

The FAP‑440 Dual Ray Detectors have 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 FAP‑440 Dual Ray Detectors are part of a
two‑piece modular design for detector assemblies. An
FAP‑440 Dual Ray Detector attaches to an FAA‑440

u Flexible work modes determined by the control

Series Analog Base. The base’s security locking tab
prevents any unauthorized detector removal from the
base.

Advanced technology for false alarm reduction

Dual ray technology: The detector contains two
emitters operating at different wavelengths. The
different wavelengths enable better differentiation of
particle sizes to distinguish smoke particles from other
particles that may be present. This results in fewer
false alarms due to dust, water vapor, or cigarette
smoke.
Multi‑sensor detector: The multi‑sensor detector
contains a photoelectric smoke sensor and a heat
sensor. Either sensor can detect a fire and activate an
alarm signal. The smoke threshold is adjustable (see
Sensitivity Calibration and Compensation below) while
the heat sensor’s threshold is set at 135°F.
Multi-criteria detector: The multi‑criteria detector also
contains smoke and heat sensors that work
independently of each other, but in conjunction with
the CO sensor. In this model, an alarm signal will be
activated by either one or both of the sensors only if
the CO level is also exceeded.

Notice

Carbon monoxide sensors:

Detectors that contain carbon monoxide (CO)
sensors must not be used as stand-alone CO
detectors. The CO sensor is supplied to confirm
the presence of CO as a by-product of combustion
thereby reducing false alarms, but not to confirm
the presence of CO as a hazardous gas.

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.

Sensitivity Calibration and Compensation

The sensitivity of the smoke sensor is programmable
with 12 levels from which to choose. Throughout its
normal life cycle, the smoke detector monitors itself
against its factory calibrated level and periodically
compensates itself to keep the sensitivity at its
programmed level. When the detector is excessively
contaminated, this condition will be annunciated at
the control panel.

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 smoke
detectors should be no more than 30 ft (9.14 m).

Wiring Considerations

The control panel communicates to the detectors via
the analog addressable loop, which allows the use of
standard non‑twisted, non‑shielded wiring for the
SLCs.
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.

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
