Special detectors – tailored to suit your needs

Our special detectors are put into operation when standard detectors, such as optical smoke detectors, are unsuitable due to challenging environmental conditions, or if there are particular risks or safety requirements to take into account. Special detectors feature specialized sensors developed for specific applications or to meet specific requirements.

Which special detectors are available from TELENOT and how are they used?
TELENOT offers special detectors with a variety of technologies, for example

• smoke aspiration systems
• linear heat detectors
• linear smoke detectors

They offer the best protection in challenging environments:

The smoke aspiration system (RAS) works based on the same principle as an optical smoke detector. Instead of a circular smoke detector on the ceiling, we install a pipeline that sucks in smoke from various points within the room and guides it to a smoke detector in a sensor chamber. The sensor can then detect the tiniest smoke particles in the air sample. RAS systems are particularly useful in challenging environmental conditions. Frequent use-cases include elevator shafts, high bay warehouses, warehouses, electrical substations, or animal stalls.

Linear heat detectors are often used in tunnels, parking garages, or on flat roofs, where they can detect temperature changes along a sensor cable.

Linear smoke detectors consist of a transmitter and receiver located opposite each other. The transmitter emits a beam of light which the receiver detects. If smoke comes between the transmitter and the receiver, it absorbs the light. The detector then triggers an alarm after the light has been reduced by a defined amount. These detectors are used to monitor large, open areas such as warehouses, production sites, air terminals, or malls, as well as in rooms with high ceilings, or very dirty or dusty environments.

What do you need to take into account when using special detectors?

Whether or not a special detector will work for you is heavily dependent on the specific requirements and risks associated with the building. In addition, installation and use of special detectors must comply with current local standards and regulations. Most countries have specific guidelines and standards for fire detection and fire alarm systems and solutions. Which specific detector is required is therefore a decision that must be made by fire detection technology professionals.
