F2121 Mk2 Digital Breathing-Air Flow Distribution Panels 

As standard, the unit is fitted with a 24 Volt lead acid rechargeable battery, this provides 10 hours of operation and can be re-charged from either a 110 Volt or 230 Volt supply. Alternatively the F2121 can be operated directly from a mains supply. 

 

The F2121 MK2 incorporates 4 flow channels each with electronic mass flow meters, all linked to a microprocessor alarm system. The input pressure can be initially adjusted by a pressure regulator. The flow from each channel is then easily adjusted with a ‘fine tune’ control valve and the sophisticated alarm system allows each flow channel to be pre-set with its own airflow parameters. In the event of the alarm being activated, an audible warning will sound and a visual beacon flash on top of the unit. The LED display will identify the reason why the alarm has been activated. The alarm also features a mute option to silence the audible alarm and allow verbal commands to be issued, however the visual beacon will continue to flash. An automatic feature resets the alarm if the airflow increases again to above the minimum level. The alarm includes the following operating parameters:- 

 

• Airflow monitoring – the alarm will activate if the airflow falls below or rises above the preset level 

• Low pressure - measured at the inlet to the unit 

• Fully charged battery – the alarm will bleep every 7 seconds to indicate the battery is fully charged. 

• Low battery level - when the unit measures that the battery voltage is low a warning bleep will sound every 2.5 seconds. 

• Very low battery level – the alarm will sound continuously.
