Early fire detection with TITANUS® air sampling smoke detectors

Detect fires early, with no false alarms

Every second counts where fire is concerned. The faster a fire is detected, the faster action can be taken in order to prevent more serious damage. The head start that WAGNER’S TITANUS® air sampling smoke detectors offer can be crucial to a company’s continued existence. After all, fire is an ever-present risk that is not to be underestimated. Material assets, operational processes, people and the environment are always exposed to this threat, which is why appropriate fire protection solutions are so important.

According to statistics by Siegfried Bussenius, the majority of damaging fires (68 %) develop from prolonged smouldering fires. Conventional smoke detectors have a crucial disadvantage there: depending on whether they are optical fire detectors or heat detectors, these smoke detectors will only react to high concentrations of smoke or increased temperatures within the protected area. By that time it is often too late to implement countermeasures.

WAGNER’s highly sensitive air sampling smoke detection systems (previously known as aspirating smoke detection systems) offer early smoke detection in the pyrolysis phase along with graduated alarms. High response sensitivity, continuous air sampling, and a graded alarm-activation concept ensure early detection of smouldering and incipient fires, so that users have time to react to alarms appropriately.

TTITANUS® air sampling smoke detectors - functional principle

When it comes to early fire detection, WAGNER relies on optical air sampling smoke detectors with HPLS (High Power Light Source) technology.

Air sampling smoke detection system structure is based on a pipe system with air sampling points and a base unit with a detector module. For project configuration purposes, each of the air sampling points correspond to one point-type smoke detector. Air sampling smoke detectors use vacuum pressure to take continuous samples of the ambient air, and guide these samples to a sensitive optical detector that examines them for the smallest traces of smoke particles.

Detection chamber sensitivity is expressed in terms of light obscuration per meter; WAGNER’s air sampling smoke detectors have high to very high sensitivity levels (EN 54/20 Classes A, B and C). They react with up to 2,000 times more sensitivity than conventional point-type detectors.

A fan inside the base unit generates the vacuum pressure needed to sample the air. Integrated air flow sensors continually monitor the pipeline system for potential blockages or breaks in order to ensure that the air sampling process functions correctly.

Air sampling smoke detection systems can be configured perfectly to individual situational needs, and compared to point-type systems, they detect fires much earlier and with much greater security against false alarms. Increased security against false alarms in modern air sampling smoke detectors thanks to LOGIC.SENS: If the air contains aerosols, the system compares the signal paths they create against previously learned fire patterns. If the signal path matches a fire pattern, an alarm is triggered.
