FAAST FLEX offers a highly flexible and cost-effective ASD solution for a wide range of applications such as small to medium warehouses, cold storage, elevator shafts, ceiling and underfloor voids, transformer and electrical rooms, rest rooms and the like. FAAST FLEX provides consistent detection with minimum nuisance alarms to reduce operational costs enabled by improved detection chamber design.

FAAST FLEX allows a high degree of flexibility through pre-engineered pipe network designs, and true out-of-the-box operation with a built-in user-friendly configuration and control mechanism. It can be configured and commissioned using a 10-line dip-switch arrangement without the need for a special tool.

Through its Bluetooth interface and associated smartphone applications, FAAST FLEX offers extended configuration options and rapid diagnostics.

FAAST FLEX is easy to install with reduced effort and time; 1-man installation with an installation template, different orientations, direct wall-mounting and ample room for wiring. Through its modular design and field replaceable components, FAAST FLEX allows convenient in-field service and maintenance, thus minimizing downtime and reducing ongoing maintenance costs.

How It Works

Air is drawn into the FAAST FLEX through a network of air sampling pipes by speed adjustable aspirator. Each pipe inlet has an airflow sensor that monitors airflow changes in the pipe. Inside the FAAST FLEX, a sample of air is filtered and passed into the detection chamber and analysed for the presence of very small amounts of smoke. Air is exhausted from the FAAST FLEX and may be vented back into the protected zone.

Video Transcript

Small and medium businesses cannot afford disruption. For them, preventing fires is vital, but detecting a fire threat early enough to prevent disruption can be challenging. Xtralis FAAST FLEX Aspirating Smoke Detection. FAAST FLEX helps you detect fire threats faster while reducing your total cost of ownership in comparison to traditional smoke detection technologies. It combines effective and reliable smoke detection with quick and easy design, installation, commissioning, and maintenance all while enhancing the user experience. But how? FAAST FLEX actively monitors the air via an extensive network of pipes with sampling holes covering up to 2,000 square meters, 21,000 square feet. A speed-adjustable aspirator draws air, while an airflow sensor monitors changes in the pipes. The air sample is filtered and then passed into the detection chamber for analysis.

This way, you can detect the early signs of a potential fire threat and take action to prevent disruption and damage to your business. With FAAST FLEX, you get best-in-class performance with minimum nuisance alarms. This is thanks to the extensive detector coverage combined with reliable smoke detection and flow monitoring using advanced ultrasonic flow sensing technology. FAAST FLEX is also easy to design and install. It comes with pre-engineered pipe networks, screwless assembly, and ample wiring space. Its patented packaging design featuring an intuitive template enables you to install the device in less than two minutes. FAAST FLEX also gives you flexible mounting options, thanks to a patented reversible flexible cover.

Commissioning is made faster by out-of-box operation. Two configuration options are available depending on your needs. A built-in user-friendly dip switch-based configuration and an extended configuration and test mode, thanks to a Bluetooth interface with a mobile app. FAAST FLEX is very easy to maintain, helping you reduce downtime and associated costs. The extensive pipe network means you can install the device in a convenient location that makes maintenance easier than ever before. Not only that, the modular design and field-replaceable components enable easier in-field service operations. Ease of use is another key feature of FAAST FLEX. The Bluetooth interface with the mobile app allows you to control the device remotely. You can easily view its status in real-time and carry out rapid diagnostics and troubleshooting.

FAAST FLEX has an operating temperature of -40 degrees Celcius, meaning you can deploy it safely in refrigerated storage facilities. It is also ideal for low-noise environments, thanks to its quiet operation. All these features make FAAST FLEX the optimum ASD solution for a variety of applications across small to medium businesses, including warehouses, refrigerated storage facilities, elevator shafts, ceiling and underfloor voids, and transformer and electrical room.
