Aspirating Smoke Detection



Aspirating Smoke Detection is based around a central detection unit which continually draws air through a network of small and unobtrusive pipes. Aspirating smoke detectors use discrete sampling pipes with multiple holes and a fan unit to draw air through the pipes from the protected area. As this happens the air is filtered, removing any contaminants or dust to avoid false alarms, before it is processed by the highly sensitive detection unit. As the air moves through the units sampling chamber, the detection unit uses a laser-based light source to measure the amount of light that is scattered (or reflected) by smoke particles in the chamber.

Aspirating smoke detectors are highly sensitive and can detect smoke even before it is visible to the human eye, providing a very early warning of a fire event and prompting investigation at the earliest smoldering stage of fire when it can be easily dealt with.

This type of fire detection is suitable for environments where highly sensitive rapid smoke detection is required. Sampling points are often very discrete and pipe networks can be easily hidden, this makes aspirating smoke detection suitable for environments where the aesthetics of a property are to be maintained. Aspirating smoke detection can also be used in dusty or dirty environments as long as the correct design, installation and maintenance processes are followed.

Eurofyre support a wide range of Xtralis Aspirating Smoke Detectors including:


VESDA aspirating smoke detectors by Xtralis, offer very early warning aspirating smoke detection with continuous air sampling to provide the earliest possible warning of an impending fire. This allows fires to be contained and investigated with an appropriate response time to prevent injury and property damage, with minimal disruption to a business.

VESDA detectors use an aspirating fan – capable of functioning in high air flow areas, air-conditioned environments and clean rooms – to actively draw air through rigid, 25mm pipes, perforated along their length with sampling holes. Areas of up to 2,000m² can be protected by these high sensitivity smoke detectors which feature 100 metres of pipe length per inlet depending on the detector.

VESDA aspirating smoke detectors have multi-level warnings and a wide sensitivity range that does not degrade or change over time. Therefore, even the smallest levels of smoke can be detected before a fire has time to develop.

VESDA systems are manufactured using targeted Six Sigma techniques and ISO 9000 standards and are certified by regulatory bodies worldwide.

VESDA early warning detectors are available in a variety of models to accommodate an expansive range of environments and applications. From small to very large, open spaces and from the cleanest to the dirtiest environments, VESDA multi-level detection provides reliable, high-sensitivity, very early warning smoke detection.


VESDA-E is the next generation of aspirating smoke detection and offers unique features to increase sensitivity, target detection of the most common fire threats, Improve flexible networking, improve programming capabilities and provide up to 40% improved coverage in high airflow areas. This is achieved using a number of innovative technologies such as VESDA Smoke+, VESDA Analytics, VESDA Connect and VESDA TCO.


ICAM detectors transform traditional point detectors into powerful aspirating systems for use in harsh, dusty and inaccessible spaces. ICAM detectors use a powerful aspirating fan to draw air into the detection chamber which can house virtually any manufacturer’s conventional or analogue addressable point detectors.
