Multi-Criteria Fire Detector [with ASAtechnology™]
Model FDOOT441
Product Overview
Model FDOOT441 is an advanced, flexible
multi-criteria fire detector incorporating a
redundant optical / thermal sensor. Additionally, Model FDOOT441
utilizes
ASA
technology a distinctive forward / backward, light-scattering technology that
provides
high-tech, unparalleled fire detection to the widest range of fire types
allowing the detector to distinguish non
-threatening deceptive phenomena.
Each FDOOT441
unit is UL 268 7th edition listed incorporating advanced built-in
ISO
technology- True Class-X SLC operation (use is optional) greatly improving
system
reliability and circuit integrity while providing advanced addressable fault
finding.
The unit may be
programmed as a high-sensitivity detector, with a 0.2 %/ft Pre-Alarm
threshold and 1.0
%/ft Alarm threshold thus meeting NFPA 76 requirements
(
Standard for the Fire Protection of Telecommunications Facilities) as a Very Early
Warning Fire Detector
(VEWFD).
Every
FDOOT441 unit is a multi-purpose, addressable detector providing a
complete
contemporary solution meeting fire detection needs for commercial
facilities.
Each individual FDOOT441 sensor can be field programmed for
simultaneous and / or independent functionality, depending upon the precise
customer and application requirements.
F
or example, the detector can simultaneously utilize the optical and heat sensors
for enhanced multi
-criteria fire detection, as well as provide independent outputs
for heat detection. Any combination of the sensors is possible.
T
he detector is very versatile, and meets the following fire-industry standards:
Multi-criteria fire detector ( UL 268 7
th
edition)
Heat detector ( UL 521) with five (5) possible field-selectable
temperatures; combined with four (4) rate-of-rise options
Direct, in-duct (plenum) detector ( UL 268A)
Supervisory monitoring for temperature ranges
NFPA 76 (Telco Standard) as VEWFD
Low-temperature warning signal at 40°F
(4.4°C) for sprinkler systems, per NFPA 25 /
NFPA 72
For instance, the signals from the detector’s
sensors are monitored and processed via
the
ASApatented algorithm technology,
which combines the signals into
a neural
network to create an intelligent, multi
-
criteria addressable detector.
