FLASHSCAN®
WORLD LEADING DETECTOR PROTOCOL
At the heart of the AFP-3030 is a set of detection devices and device
protocol — FlashScan. FlashScan is an all-digital protocol that gives
superior precision and high noise immunity.
As well as giving 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 of
communication also allows the AFP-3030 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 FlashScan® detectors have bicolor LEDs that can be coded to
provide diagnostic information, such as device address during Walk
Test.
ONYX INTELLIGENT SENSING REDUCING
UNWANTED ALARMS
ONYX Intelligent Sensing is a set of software algorithms that
provide the AFP-3030 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 AFP-3030.
DriftCompensationandSmoothing. 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 AS1851. Smoothing filters are also provided by
software to remove transient noise signals, usually caused by
electrical interference.
MaintenanceWarnings. When the drift compensation performed for a
detector reaches a certain level, the performance of the detector may be
compromised, and special warningsare given. There are three warning
levels: (1) Low Chamber value; (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.
SensitivityAdjust. 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
pre-alarm sensitivity can also be selected, based on predetermined
levels of alarm. Pre-alarm operation can be latching or self-restoring,
and can be used to activate special control functions.
Self-OptimizingPre-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.
Co-operativeMultiDetectorSensing.A patented feature of
ONYX Intelligent Sensing 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 sensitivityto actual smoke
by a factor of almost two to one.
AlarmVercationFacility(AVF). All devices are capable of performing
an alarm verification facility, whereby communication between the panel
and the device performs an additional confirmation of an alarm event in
order to reduce unwanted spurious alarms.
FIELD PROGRAMMING OPTIONS
Autoprogram is a timesaving feature. The FACP “learns” what
devices are physically connected and automatically loads
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.
Keypad Program Edit. The AFP-3030 has the exclusive feature of
program creation and editing capability from the front panel keypad,
while continuing to provide fire protection. The architecture of the AFP-
3030 software is such that each point entry carries its own program,
including control-by-event links to other points. This allows the program
to be entered with independent per point segments, while the AFP-
3030 simultaneously monitors other (already installed) points for alarm
conditions.
VeriFire Tools. VeriFire Tools is a non-propretary offline programming,
test and reporting 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 program for the AFP-3030
and the entire network 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.
VeriFire Tools can use Noti-Fire-Net to configure, diagnose or report on
any node(s) from any location around the network.
ONYX INTELLIGENT TESTING
IntelligentWalkTest. One man walk test allows the testing engineer
to activate devices on the system to ensure correct operation and
connection. During a walk test ONYX AFP-3030 will deactivate intelligent
algorithms in the devices resulting in a further 60% reduction in test time.
AlarmTest. When Alarm Test is activated on a specific device or devices
on the system, the test engineer is capable of verifying the cause and
effect of the device in the same manner as an alarm event removing the
need to actually activate a device which may be difficult to access for
this task.
Automatic Device Test. Each Notifier FlashScan detector is capable
of performing an automatic device test each 24 hours to ensure correct
communication and operation between FACP and device.
