Fire detection and fire alarm system - Part 28: Non-resettable line type heat detectors
This European Standard applies to non-resettable line type heat detectors consisting of a sensing element using an electrical sensor cable connected to a sensor control unit, either directly or through an interface module to a control and indicating equipment intended for use in fire detection and fire alarm systems installed in buildings and tunnels. The non-resettable sensing element has a fixed temperature alarm threshold and does not distinguish between short circuit and alarm condition. This standard also covers non-resettable line type heat detectors intended for use in the local protection of plants and machinery. Non-resettable line type heat detectors with special characteristics and developed for specific risks are not covered by this standard. This standard specifies the requirements and performance criteria. This standard specifies the corresponding test methods and the evaluation of conformity of the product to the standard.
Brandmeldeanlagen - Teil 28: Nicht-rücksetzbare linienförmige Wärmemelder
Diese Europäische Norm gilt für nicht-rücksetzbare (digitale) linienförmige Wärmemelder mit einem Sensorelement, das ein elektrisches Sensorkabel nutzt, welches mit einer Auswerteeinheit oder, entweder direkt oder über ein Interface-Modul, mit einer Brandmelderzentrale verbunden ist, und dienen der Verwendung in Brandmeldeanlagen, die innerhalb und außerhalb von Verwendung in Brandmeldeanlagen, die innerhalb und außerhalb von Hoch- und Tiefbauten installiert sind.
Das nicht-rücksetzbare Sensorelement hat einen festen Temperatur-Alarmschwelle und unterscheidet nicht zwischen Kurzschluss und Alarmzustand.
Diese Europäische Norm gilt auch für nicht-rücksetzbare linienförmige Wärmemelder, die zur Einrichtungsüberwachung von Anlagen und Einrichtungen vorgesehen sind.
Nicht-rücksetzbare linienförmige Wärmemelder, die spezielle Eigenschaften haben und für Fälle mit besonderen Risiken entwickelt wurden, sind nicht Gegenstand dieser Norm.
Diese Europäische Norm legt Anforderungen und Leistungskriterien, die entsprechenden Prüfverfahren und die Bewertung der Konformität des Produkts mit dieser Norm fest.

Introduction
Non-resettable Line Type Heat Detectors (NLTHD) have been used for a considerable number of years and
are incorporated into fire detection systems and in some countries even into fire alarm systems if accepted by
the fire brigade. These detectors are typically used in areas where point type heat detectors are presented
with challenging environmental characteristics and also, where access to the detectors, may significantly
influence the fire alarm system design.
This standard defines the minimum system functionality for NLTHD products.
Due to the various applications for NLTHD, it is necessary to devise separate environmental classification
tests for the sensing element and the sensor control units of these systems. It is not the purpose of this
standard to define applications or how NLTHD should be used in applications.
Generally NLTHD operate on using the same basic principle. However, they can have different performance
with respect to the temperature response. Therefore they have been classified by a type code which reflects
the nominal alarm temperature, the tolerance range and the maximum ambient temperature at which they
could be used.
