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

ASAtechnology™ 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

ISOtechnology™ - 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.

For 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.

The detector is very versatile, and meets the following fire-industry standards:

• Multi-criteria fire detector ( UL 268 7

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 ASA–patented algorithm technology,

which combines the signals into a neural

network to create an intelligent, multi-

criteria addressable detector.
