ADDRESSING SAFETY SYSTEMS WITH INTELLIGENCE
Fire Detection - Addressable
The Protec Algo-Tec™ 6300 Interactive Digital
Addressable System unwrapped:
The Protec Algo-Tec
TM
6000 protocol developed by
Protec’s in-house Research and Development team is
utilised by the Protec Algo-Tec
TM
6300 interactive digital
addressable fire control systems. Immunity to false
alarms, more responsive fire detection, and ease of use
has all been achieved to develop one of the most reliable
systems available.
Protec Algo-Tec™ 6300
The name Algo-Tec
TM
is a derivative of Protec algorithms.
Algorithms are logical mathematical procedures for
solving problems. Protec have developed fire detection
algorithms coupled with fuzzy logic specifically designed
to reduce unwanted fire alarms and to enhance the
sensitivity of the system to true fire phenomenon. The
Algo-Tec
TM
algorithms are exclusively utilised by the
Protec Algo-Tec
TM
6400 and 6300 Interactive Digital
Addressable Fire Control Systems.
Interactive
Algo-Tec
TM
evaluates the data of each fire sensor
and is able to learn from the information received.
This may simply be to recognise that a sensor is
becoming contaminated or in a dirty environment
and to automatically increase the alarm threshold
to compensate for the background levels (Threshold
Compensation).
More complex Algo-Tec
TM
functions include the ability
to discriminate between certain fire and non-fire
conditions, filtering out certain environmental stimuli,
and increasing the sensitivity of a sensor when an
increase in temperature is detected.
The net effect of the interaction between the sensors
and the Algo-Tec
TM
decision making is enhanced
performance, through immunity to false alarms and more
responsive fire detection.
Digital Addressable
The data communication between the sensors and the
control equipment is Digital.
The Algo-Tec
TM
protocol utilised by the 6000 system
enables high levels of data to be transferred, providing
far more detailed information than was previously
achievable with analogue addressable systems. It should
however be noted that many analogue addressable
systems use digital communication but do not transfer
the high levels of data associated with the Algo-Tec
TM
protocol. Speed, stability, excellent EMC and security all
serve to enhance the Algo-Tec
TM
Digital signalling. Why
go analogue addressable when you can now choose
Algo-Tec
TM
Digital Addressable.
