FAAST FLEX Aspirating Smoke Detector

FAAST FLEX aspirating smoke detectors provide a highly-flexible and cost-effective aspirating smoke detection solution for a wide range of applications such as small to medium sized warehouses, cold storage facilities, lift shafts, ceiling voids, underfloor voids, transformer and electrical rooms and many more.

FAAST FLEX is available as a one-channel or two-channel detector. Each sensing channel consists of an inlet, a metallic filter, a sensing element and a flow monitoring system. FAAST FLEX detectors use an improved detection chamber design to provide constant detection with minimal nuisance alarms.

These innovative detectors allow a high degree of flexibility through pre-engineered pipe network design and out-of-the-box operation. They have a built-in user-friendly configuration and control mechanism and can be configured without the need for specialist tools.

EN54-20 Aspirating Smoke Detection Sensitivity Classes

EN54-20 specifies three classes of sensitivity to help with the variety of applications aspirating smoke detection can be used for. This is to ensure that the most appropriate sensitivity aspirating smoke detector will be selected for the proposed application/area.

These three classes are:
1Class A – Very High Sensitivity
For the earliest indication of smoke so that early measures can be initiated before any significant damage is incurred in areas containing high value, critical or strategically important artefacts or operations such as data centres.
2Class B – Enhanced Sensitivity
Enhanced sensitivity for effective early detection in challenging environments or within critical equipment e.g. to combat smoke dilution where there is high airflow or where the ceiling is higher than normal.
3Class C – Normal Sensitivity
As an alternative to point or beam type smoke detectors (normal sensitivity) for a variety of physical reasons e.g. maintenance access, building deflection, dilution of smoke and obstructions to line-of-sight such as cold stores and warehouse facilities.
