Aspirating Smoke Detection

Aspirating smoke detectors deliver highly accurate standard detection, early warning fire detection, and very early warning fire detection for a variety of applications including mission-critical facilities such as data centres

FAAST FLEX

FAAST FLEX aspirating smoke detectors

The FAAST FLEX is an aspirating smoke detector featuring very quiet operation and a -40 °C operating temperature rating.

The product is available as a single channel or dual channel detector. Each sensing channel includes a pipe inlet, a metallic mesh filter, a smoke sensor and a flow monitoring system. Both models have a single aspirator (fan) and a single exhaust outlet. The FAAST FLEX is powered by an external 24 volt dc power supply.

FAAST FLEX detectors may be configured using internally mounted DIP switches.

Components subject to periodic maintenance are designed to be easily reachable in any cabling situation. An in-line filter can be installed on the piping close to the inlet in order to improve protection to the sensing elements in particularly harsh (e.g. dusty) environments.

How It Works

FAAST FLEX detectors draw air from the monitored environment, through a network of air sampling pipes into the detection chamber. An alarm is triggered if the smoke level exceeds the pre-configured threshold. The exhaust should be returned to the monitored environment.
