VESDA FAAST Automatic Purging Unit- Freezer Applications

Under §8 of the DGVO these purging units are pressure equipment with low risk potential, designed and manufactured in accordance with the engineering practice of a Member State, and the CE labelling of the device expressly does not result from the guideline 2014/68/EU.

F-BO-AFE70-3 is an automatic purging unit of the Automatic Purging Units Series F-BO-AFE70, working on the sampling pipe network of an aspirating smoke detector. Its solenoid valve gives a typical air flow rate of approx. 5,000 l/min (ANR) at 0.7MPa (7bar), which suits even larger and further-flung pipe systems, while the DF designation covers refrigeration area down to -20°C and allows use in environments with low temperatures.

The purging unit does not represent an additional air resistance in the sampling pipe network and therefore does not have to be included in the calculation of that network, although the values specified in the project planning guidelines of the aspirating smoke detector must not be exceeded.

Operating conditions are shown on the status LED, and the purging program, the internal clock, the time and the device number are all set at the unit, by the user or by the installer. A Slave activation output supports master-slave working with direct actuation through the fire detection control panel, alongside the standard connection with indirect actuation through the panel, both in accordance with EN 54-13.

CE marking rests on the Electromagnetic Compatibility Directive 2014/30/EU with EN 55022:2010 and EN 50130-4:2011 + A1:2014, and expressly does not result from the guideline 2014/68/EU.
