PAF - The Smart Heat- & Fire Detection SystemDetection and Alarm Devices Fire warning is a basic function and often early Detection
of excessive high temperatures is most critical.Excessive heat, even without the presence of smoke, canbe a potential hazard of fire or explosion.The prevention of a potential fire, caused by excessiveheat, allows corrective action to avoid igniting flames. In conclusion - effective action can save lifes and protecthigh value buildings and assets.
The system can be used for single or unused Heat Detec-tion using 2 equal switching temperatures. Ex e & Ex dboxes available. It also can be using by programming 2(or more) different switching temperatures. Also the use ofdifferent Salt-filled Inconel wires is possible. The flexibleand highly effective system gives accurate data acquisitionand warning of excessive high temperatures.

NPT-threads:
National Pipe Thread Tapered Thread (NPT) is a U.S. standard for tapered threads used on threaded pipes and fittings. BSP is a British Pipe thread (see also Whitworth-threads)
Jointing threads: These are pipe threads where pressure-tightness is made through the mating of two threads together. Additional seal tapes or thread sealant compounds might be necessary for both NPT & BSP-
joints.
MIP: stands for Male Iron Pipe, or Male International Pipe, or MPT Male Pipe Thread. It is a term for pipe fittings.
FIP: stands for Female Iron Pipe, or Female International Pipe, or FPT. It is a term for pipe fittings that MIP fittings fit into.
Mating of NPT and BSP is not possible due to different cone angle, threads per inch, depth and pitch.
Das National Pipe Thread (NPT-Gewinde, NPT-Rohrgewinde) nach ASME/ANSI B1.20.1 ist eine US-
amerikanische Gewindenorm für selbstdichtende Rohrverschraubungen entsprechend der europäischen Anschauung..
Die Dichtung wird dadurch erreicht, dass die Gewinde kegelig angeordnet werden. Bei Zusammenschrauben konventioneller Rohrgewinde wird zusätzlich ein Dichtmittel (z. B. Teflonband, Hanf) zwischen die Gewinde gelegt. Im Gegensatz dazu benötigt das National Pipe Thread - Dryseal Form (NPTF-Gewinde, NPTF-Rohrgewinde) nach ASME/ANSI B1.20.3 primär kein Dichtmittel. Häufig werden jedoch flüssige Schraubendichtmittel oder Hanf oder Teflon zur Sicherung eingesetzt. Gelegentlich werden NPT-Gewinde auch als MPT (Male Pipe Thread) oder FPT (Female Pipe Thread) und auch als MIP (Male iron pipe) and FIP (Female iron pipe) bezeichnet.
Gegenüber dem Withworth-Gewinde, welches auch als British Standard Pipe (BSP) bekannt ist, sind die Durchmesser, Gangzahl (Steigung in Gängen pro Zoll, threads per inch) als auch Kegelwinkel leicht unterschiedlich, so dass die beiden Gewinde nicht miteinander verschraubbar sind.

HDL-units are constructed and manufactured according CE, this includes Equipment- and protectionsystms for dedicated and proper use in explosion-hazardous areas (94/9/EG), as far as this regulation is applicable.
Effective ignition source is a term defined in the European ATEX directive as an event which, in
combination with sufficient oxygen and fuel in gas, mist, vapor or dust form, can cause an explosion. Methane, hydrogen or coal dust are examples of possible fuels.
Effective ignition sources are:
Lightning strikes.
Open flames. This varies from a lit cigarette to welding activity.
Mechanically generated impact sparks. For example, a hammer blow on a rusty steel
surface compared to a hammer blow on a flint stone. The speed and impact angle (between surface and hammer) are important; a 90 degree blow on a surface is relatively harmless.
Mechanically generated friction sparks. The combination of materials and speed
determine the effectiveness of the ignition source. For example 4.5 m/s steel-steel friction with a force greater than 2 kN is an effective ignition source. The combination of aluminium and rust is also notoriously dangerous. More than one red hot spark is often necessary in order to have an effective ignition source.
Electric sparks. For example a bad electrical connection or a faulty pressure transmitter. The
electric energy content of the spark determines the effectiveness of the ignition source.
High surface temperature. This can be the result of milling, grinding, rubbing, mechanical friction in a stuffing box or bearing, or a hot liquid pumped into a vessel. For example the tip
of a lathe cutting tool can easily be 600 degrees Celsius (1100 °F); a high pressure steam pipe may be above the autoignition temperature of some fuel/air mixtures.
Electrostatic discharge. Static electricity can be generated by air sliding over a wing, or a non-conductive liquid flowing through a filter screen.
Radiation.
Adiabatic compression. Air is pumped into a vessel and the vessel surface heats up.

ATEX Directive (94/9/EC)
The ATEX Directive 94/9/EC ("ATmospheres EXplosibles", French for explosive atmospheres) for CE Marking
addresses Potentially Explosive Issues.
The Directive 94/9/EC became mandatory within the European Union as of July 2003. The new ATEX Directive
based on the New and Global Approach replaces three Old Approach directives, 76/117/EEC, 79/196/EEC and
82/130/EEC.
ATEX applies to all kind of, electrical or non-electrical equipment, machines and industrial installations, placed in
potential explosive Atmospheres.
It also applies to safety devices, controlling devices and regulating devices intended for use outside potentially
explosive areas, but required for or contributing to the safe functioning of equipment and protection systems with
respect to the risks of explosions.
Equipment in the scope of the ATEX Directive is divided into groups and categories depending on the intended use
and the duration or frequency of the presence of the explosive atmosphere.
Informationen zur ATEX Betriebsrichtlinie 1999/92/EG Diese Information ersetzt das Studium und die Anwendung der Richtlinie NICHT.
Die ATEX Betriebsrichtlinie 1999/92/EG (auch inoffiziell als "ATEX 137" bezeichnet, wegen des relevanten Art. 137 des EG-Vertrages) über die Mindestvorschriften zur Verbesserung des Gesundheitsschutzes und der Sicherheit der Arbeitnehmer, die durch explosionsfähige Atmosphäre gefährdet werden können. Diese Richtlinie wurde 2002 im Rahmen der Betriebssicherheitsverordnung in deutsches, bzw. durch die Verordnung explosionsfähige Atmosphären (VEXAT) in österreichisches Recht umgesetzt. Diese Richtlinie enthält grundlegende Sicherheitsanforderungen die der
Betreiber/Arbeitgeber umzusetzen hat. Dazu gehören:
Vermeidung oder Einschränkung der Bildung explosionsfähiger Atmosphäre (primärer Explosionsschutz)
Vermeidung wirksamer Zündquellen (sekundärer Explosionsschutz)
Beschränkung der Auswirkung einer eventuellen Explosion auf ein unbedenkliches Maß (tertiärer oder konstruktiver Explosionsschutz)
Einteilung der explosionsgefährdeten Zonen
Gase Zone 0 ist ein Bereich, in dem
gefährliche explosionsfähige Atmosphäre als Gemisch aus Luft und brennbaren Gasen, Dämpfen oder Nebeln ständig, über lange Zeiträume oder häufig vorhanden ist.
Zone 1 ist ein Bereich, in dem
sich bei Normalbetrieb gelegentlich eine gefährliche explosionsfähige Atmosphäre als Gemisch aus Luft und brennbaren Gasen, Dämpfen oder Nebeln bilden kann.
Zone 2 ist ein Bereich, in dem
bei Normalbetrieb eine gefährlich explosionsfähige Atmosphäre als Gemisch aus Luft und brennbaren Gasen, Dämpfen oder Nebeln normalerweise nicht oder aber nur kurzzeitig auftritt.
Stäube
Zone 20 ist ein Bereich, in dem
gefährliche explosionsfähige Atmosphäre in Form einer Wolke aus in der Luft enthaltenem brennbaren Staub ständig, über lange Zeiträume oder häufig vorhanden ist.

IP69K (Colloquially: Kärcher Safe)
German standard DIN 40050-9 extends the IEC 60529 rating system described above with an IP69K rating for high-pressure, high-temperature wash-down applications.[5] Such enclosures must not only be dust tight (IP6X), but also able to withstand high-pressure and steam cleaning.
The test specifies a spray nozzle that is fed with 80°C water at 8–10MPa (80–100bar) and a flow rate of 14–16L/min. The nozzle is held 10–15 cm from the tested device at angles of 0°, 40°, 60° and 90° for 30s each. The test device sits on a turntable that rotates once every 12s (5rpm).
The IP69K test specification was initially developed for road vehicles, especially those that need regular intensive cleaning (dump trucks, cement mixers, etc.), but also finds use in other areas (e.g., food industry, car wash centres).

DESCRIPTION:
Die Eigenschaften des Sensorkabels:
Völlig wasserdicht korrosionsfest
schock und vibrationssicher klärt Überhitzung binnen
weniger Sekunden Hitzefest bis ~1.100°C
Damit ist das Sensorkabel seit über
50 Jahren der Industriestandard das Herz vieler Überhitzungsschutz- und Brandschutzsysteme.
Bei zig-tausenden Installationen werden diese Systeme entweder als Überhitzungsschutz eingesetzt, also als ALARM-Einrichtung und oder als Einrichtung zur hitzereduzierenden Aktion, zB Abschalten der
Anlage) oder bei der Feuerlöschung als auslösende Einrichtung um das Löschmittel freizusetzen. In vielen Fällen werden auch kombinierte Funktionen wie systemabschaltender Überhitzungsschutz UND Auslösen der Löscheinrichtung eingebaut.
STANDARD DATA: Alarm Temperaturen: 124°C, 154°C, 204°C, 302°C, 407°C, höhere Schaltpunkte nach technischer Klärung
T max reversibel: bis max. 1100°C

FUNCTION: Der Inconel-Röhre ist mit einem chemisch behandelten eutektischen Salz gefüllt. Unter normalen Umständen ist der Widerstand / Leitfähigkeit des dotierten Salzes so hoch, daß es zu „keinem“ Stromfluss kommt. Anm: der Stromfluß ist extrem gering) Die Eigenschaft des Salzes ist es, bei
Erreichen der Nominaltemperatur den Widerstand abzusenken und damit leitend zu werden. Damit werden der Innenleiter mit dem Mantel leitend verbunden und genau auf den dotierten Nominalwert wird das Alarmpanel aktiviert..

FUNCTION:
Bei einem typischen OVHT/Feueralarmsystem gibt es üblicherweise 2 identische Kabelschleifen.
Diese können je nach Planung & Layout entweder in Serie oder parallel geschalten werden. Die Auslegung kann sich wie folgt darstellen: Beide Schleifen für Überhitzung oder eine Schleife für Überhitzung, die andere Schleife für Feuer. Somit kann klar und ohne den Einsatz von weiterer Elektronik bei Erreichen der Nominaltemperatur = Schalttemperatur der Alarm geschalten oder auch zB eine Löscheinrichtung oder Kühlung eingeschalten werden. Üblicherweise muß bei elektronischen Lösungen eben mehr oder weniger Elektronik zum Einsatz
kommen. Nicht nur, daß dies die Fehleranfälligkeit erhöht, eine elektronische Lösung gestattet auch nicht mehr, daß der auslösende Schalter selbst den Alarm auslöst oder zB ein Löschventil öffnet. Bei fest eingestellten Punktdetektoren muss erst an dem jeweils vorgegebenen Punkt die Alarmtemperatur erreicht um den Schalter auszulösen. Ist die Hitzequelle zwischen 2 Schaltern kann es zu einem entsprechenden Zeitverzug kommen, bis der eine oder andere Schalter auslöst. Das HT-CFD – Inconel-Kabel wird bei Erreichen der Nominaltemperatur systeminherent AN JEDER
BELIEBIGEN STELLE leitend und damit „schalten“. Diese technische Lösung gestattet damit beim allerersten Auftreten von Überhitzung die Gefahr bannen zu können, noch bevor es zu einem Brand
kommt.

ALARMLINE DIGITAL
Comprises a twin-conductor "switching" cable with temperature-sensitive insulation
protected by a special sheath. It operates by melting of the insulation between the conductors
at a pre-determined temperature. This creates a short circuit which is detected by a simple
electrical device, which in turn provides a fire alarm signal. Fault conditions are detected by
continuous monitoring for an open circuit state.
ALARMLINE ANALOGUE
Consists of a four-conductor cable surrounded by an outer sheath of PVC. A change in
temperature produces a change in resistance, which is monitored by an Alarmline Control
Unit, which in turn actuates an alarm signal at a predetermined level. The cable is
continuously monitored for open and short circuit fault conditions. It detects either a
localised hot spot or a lower level of temperature increrase over the entire length. It is
recoverable after operation.
