At a glance
- Automatic Purging UnitF-BO-AFE70-2 is an automatic purging unit that purges the sampling pipe network of Honeywell Aspiration Smoke Detection (ASD) systems using compressed air.
- Six Purging ProgramsSix user selectable preventive or event-triggered purging programs are provided, with short or long purging cycle options.
- Solenoid Valve Flow RatesTypical solenoid valve flow is 1,300 l/min at 0.2MPa, 2,300 l/min at 0.4MPa, 3,200 l/min at 0.6MPa and 3,700 l/min at 0.7MPa.
- Working Pressure LimitsThe recommended minimum pressure is 0.2MPa (2.0bar) and the maximum permissible overpressure is 0.7MPa (7.0bar).
- Supply And ConsumptionThe unit runs on 21.6 - 30 VDC, taking 8mA (normal condition) and 300mA (solenoid valve energised).
- Housing And EnvironmentThe 204 mm wide, 160 mm deep and 68 mm high housing weighs 3.2kg (approx.), is finished grey white, RAL 9002, and operates from +5°C to +50°C at max. 95% at 40°C.
- Patented Purging DesignThe patented design (AT 514912) is without air resistance as defined by EN 54-20, and several systems can be coupled in Master-Slave mode.
Description
Purging the sampling pipework with compressed air is the whole purpose of F-BO-AFE70-2, the FAAST Purging System AFE70-2 (Low Flow). It works in Honeywell ASD systems and with VESDA, ICAM and FAAST aspiration smoke detection systems, drawing on a compressed-air supply.
Six purging programs, preventive or event-triggered, cover short and long purging cycles; they run from the internal clock, an external clock timer, an external push-button, or automatically when the ASD system reports a fault, activating through FACP only. Several systems can be coupled in Master-Slave mode, and the unit is a fully integrated and compact system designed for larger pipe networks.
F-BO-AFE70-2 is an automatic purging unit that uses compressed air to clear the sampling pipe network of an aspiration smoke detection system, and is the FAAST Purging System AFE70-2 (Low Flow). It is designed for Honeywell Aspiration Smoke Detection (ASD) systems and is compatible with VESDA, ICAM and FAAST ASD systems; a compressed-air supply is required.
The housing is 204 mm wide, 160 mm deep and 68 mm high, weighs 3.2kg (approx.) and is finished in grey white, RAL 9002. Supply is 21.6 - 30 VDC, the unit drawing 8mA (normal condition) and 300mA (solenoid valve energised), and it works from +5°C to +50°C at max. 95% at 40°C relative humidity.
Air is passed by a solenoid valve at a typical 1,300 l/min at 0.2MPa, rising to 3,700 l/min at 0.7MPa; 0.2MPa (2.0bar) is the recommended minimum pressure and 0.7MPa (7.0bar) the maximum permissible overpressure. The patented design (AT 514912) is without air resistance as defined by EN 54-20.

Electrically the unit takes 21.6 - 30 VDC at 8mA (normal condition), rising to 300mA while the solenoid valve is energised. Compressed air should be at least 0.2MPa (2.0bar) and never above 0.7MPa (7.0bar), the solenoid valve passing typically 2,300 l/min at 0.4MPa and 3,200 l/min at 0.6MPa. The grey white RAL 9002 housing, 204 mm by 160 mm by 68 mm and 3.2kg (approx.), works from +5°C to +50°C.

Six user selectable preventive or event-triggered purging programs are offered, with short or long purging cycle options. A cycle can start automatically on a fault message from the ASD system (activating through FACP only), on the internal clock or an external clock timer, or by hand from an external push-button. Several systems can be coupled in Master-Slave mode, a multicoloured LED indicates the system condition, and commissioning is carried out without software tools.
