IFC-640
Intelligent Addressable
Fire Alarm System
General
As a stand-alone small-to-large system, or as a large network,
the IFC-640 meets virtually every application requirement.
Designed with modularity and for ease of system planning, the
IFC-640 can be configured with just a few devices for small
building applications, or for a large campus or high-rise application. Simply add additional peripheral equipment to suit the
application.

FlashScan®
Exclusive World-Leading Detector Protocol
At the heart of the IFC-640 is a set of detection devices and
device protocol — FlashScan® (U.S. Patent 5,539,389). FlashScan® is an all-digital protocol that gives superior precision and
high noise immunity.
In addition to providing quick identification of an active input
device, this protocol can also activate many output devices in a
fraction of the time required by competitive protocols. This high
speed also allows the IFC-640 to have the largest device per
loop capacity in the industry — 318 points — yet every input and
output device is sampled in less than two seconds. The microprocessor-based FlashScan® detectors have bicolor LEDs that
can be coded to provide diagnostic information, such as device
address during Walk Test.
Keypad Program Edit (with KDM-2) The IFC-640 has the
exclusive feature of program creation and editing capability from
the front panel keypad, while continuing to provide fire pro-
tection. The architecture of the IFC-640 software is such that
each point entry carries its own program, including control-byevent links to other points. This allows the program to be
entered with independent per-point segments, while the IFC640 simultaneously monitors other (already installed) points for
alarm conditions.
VeriFire® Tools is an offline programming and test utility that
can greatly reduce installation programming time, and increase
confidence in the site-specific software. It is Windows® based
and provides technologically advanced capabilities to aid the
installer. The installer may create the entire program for the IFC640 in the comfort of the office, test it, store a backup file, then
bring it to the site and download from a laptop into the panel.
AWACS™ Advanced Warning Addressable Combustion Sensing
AWACS is a set of software algorithms that provide the IFC-640
with industry-leading smoke detection capability. These complex
algorithms require many calculations on each reading of each
detector, and are made possible by the very-high-speed microcomputer used by the IFC-640.
Drift Compensation and Smoothing: Drift compensation
allows the detector to retain its original ability to detect actual
smoke, and resist false alarms, even as dirt accumulates. It
reduces maintenance requirements by allowing the system to
automatically perform the periodic sensitivity measurements
required by NFPA 72. Smoothing filters are also provided by
software to remove transient noise signals, such as those
caused by electrical interference.
Maintenance Warnings: When the drift compensation performed for a detector reaches a certain level, the performance of
the detector may be compromised, and special warnings are
given. There are three warning levels: (1) Low Chamber value,
usually indicative of a hardware problem in the detector; (2)
Maintenance Alert, indicative of dust accumulation that is near
but below the allowed limit; (3) Maintenance Urgent, indicative of
dust accumulation above the allowed limit.
Sensitivity Adjust: Nine sensitivity levels are provided for
alarm detection. These levels can be set manually, or can
change automatically between day and night. Nine levels of prealarm sensitivity can also be selected, based on predetermined
levels of alarm. Pre-alarm operation can be latching or selfrestoring, and can be used to activate special control functions.
Self-Optimizing Pre-Alarm: Each detector may be set for
“Self-Optimizing” pre-alarm. In this special mode, the detector
“learns” its normal environment, measuring the peak analog
readings over a long period of time, and setting the pre-alarm
level just above these normal peaks.
Cooperating Multi-Detector Sensing: A patented feature of
AWACS is the ability of a smoke sensor to consider readings
from nearby sensors in making alarm or pre-alarm decisions.
Without statistical sacrifice in the ability to resist false alarms, it
allows a sensor to increase its sensitivity to actual smoke by a
factor of almost two to one.

Field Programming Options
Autoprogram is a timesaving feature of the IFC-640. It is a special software routine that allows the IFC-640 to “learn” what
devices are physically connected and automatically load them in
the program with default values for all parameters. Requiring
less than one minute to run, this routine allows the user to have
almost immediate fire protection in a new installation, even if
only a portion of the detectors are installed.
