ARDEA

THE ARDEA DETECTOR IS PARTICULARLY SUITED TO FIRE DETECTION IN THE FOLLOWING SITUATIONS:
Industrial sheds – High rise store and traditional warehouses – Garages – Supermarkets and malls – Cinemas – Theatres – Conference rooms – Trade exhibition centres – Public buildings in general – Schools and hospitals and all other large civil or industrial spaces of all shapes and sizes.

THE ARDEA INFRARED FIRE DETECTION SYSTEM is designed to achieve or exceed the following
characteristics:
Operating distance between the opposed units up to 200 m with an area of coverage of 3.000 square meters set by the standard Pr.EN 54/14 at up to 1.600 square metres per system – Swivel movement of units to any desired horizontal or vertical working angle – Complete long-term directional stability – Sensitivity thresholds for incipient fires selectable in a continuous and wide range of levels – Automatic and instant working reset if the infrared beam is broken – High rejection of optical and electromagnetic disturbances – Extremely simple to install and
set-up – Notably reduced installation and maintenance costs.


The ARDEA models meet and exceed the European product standard EN54/12-2001 in terms both of the quantity and quality of performance levels and are certified by one of Europe’s strictest Test Competent Bodies. The models are built to an IP 44 rating but are also available in IP 65 and in explosion
proof EEXd-II°B+H2-T5/6.

THE ARDEA S/2 2P/100, SMOKE DETECTION ONLY, consists of three units the, ARDEA Tx, ARDEA Rx and the Interface INT 8BA.
The interface unit is necessary if the control unit accepts closed or open contact input for electrical faults and fires. The ARDEA Tx emits an infrared beam that can be directed as desired by means of special micrometer pointer mechanisms. The infrared beam crosses the area to be protected and strikes the Receiver unit ARDEA Rx. As it crosses this area the infrared beam collects information on any incipient fire and “transports” this by projecting it to the ARDEA Rx unit. The processing of the data performed locally at the receiver works out if the smoke information corresponds to that of the beginnings of a fire as statistically reproducible. This data processing is specific to the algorithm developed to this model.

The Rx unit has its own automatic, and practically instantaneous, sensitivity checking system effected through special circuits that mean no long-term sensitivity checks are in practice required.
LED’s can be seen through a transparent section of the front main filter window.
These show: - “Green” Supply on, “Red” Smoke alarm, “Red” Fire alarm (SF only) and “Yellow” operational fault. The system has an automatic exclusion system to deal with a situation where an object passes between the Tx and Rx units.
When the obstacle is removed, reset is automatic and normal function recommences are achieved within approx. 15 seconds.
The model can handle different smoke sensitivity levels over a very wide range so that the alarm thresholds can be selected as required for the context. Smoke sensitivity management in model S/2 can be regulated by special UTA control instrumentation or ADM and Voltmeter.
The use of this detector in civil or industrial environments that may be replete with all kinds of disturbances requires no special knowledge or skills of the operator.

THE ARDEA SF, FIRE AND SMOKE DETECTOR, consists of three units:
the ARDEA Tx, ARDEA Rx and the Interface INT8BA.
The principle of its working, its size and the quality of the devices are as those of the S/2 model. The basic
difference is that this model processes smoke and fire information, as analysed in the Receiver unit.
The processing of the data consists in translating each aspect of incipient smoke and fire identified by the receiver through electrical signals, each of which corresponding to calculations regarding a single “symptom” of a fire from smoke and/or from fire. This examination of the data is not an abstract or theoretical event but is associated with the specific working conditions of the protected area in which the detector is installed, even though this may be an area subject to many disturbances of various kinds. This model’s algorithm makes highly subtle and complex calculations possible that enable the detector to precisely identify data that reflect the presence of fire or smoke, on the basis of probabilities and proven scientific parameters. The calibration of the ARDEA SF involves the need for a portable UTA unit or ADM and Voltmeter. When this is connected to the Receiver unit it enables the operator to determine the morphology and duration of any
disturbances present in the environment to be protected.
An understanding of these values means that properly reasoned threshold settings for Fire and Smoke can be
established in accordance with the instructions given. The use of this detector in civil or industrial environments that may be subject to all kinds of disturbances requires no specialist knowledge or skills of the operator.
The size and shape are the same as for the ARDEA S/2 and ARDEA SF models.
The two models differ in the colouration of the housings’ anodising:
- For the ARDEA S/2, Black.
- For the ARDEA SF, Silver.

The interface unit is necessary if the control unit accepts closed or open input contacts for faults and fires. As with the ARDEA models it must be supplied by 24 V. DC, also true of the ARDEA S/2 and SF. Delivery may be with or without a protective plastic box.
