BX449F Gas and fire control unit for industrial use
Cod. BX449F - Gas and fire control unit for industrial use
The new BX449F is born from the elegance and prestige that has always distinguished BEINAT S.r.l. and from the home fitness concept. The device has the capacity of controlling, through its connected probes, the presence of: “explosive gas, toxic gas, fire”.
The control unit has two danger levels:
1st LEVEL, pre-alarm. This is set at 13% of L.E.L. (200ppm) for all probes.
2nd LEVEL, main alarm. This is set at 20 % of L.E.L. (300ppm) for all probes.
To facilitate event readings, the control unit has a front panel with 4 LEDs indicating which probe is currently being monitored in rotation, and a display showing the gas concentration measured on each pass.
To the BX449F you can connect up to 6 fire probes per each zone, either temperature or optical smoke detectors, through a balanced line.
The control unit’s microprocessor checks the detectors and connection line efficiency, open or short-circuited.
When the probes detect a fire, they will switch the proper relay.
The BX449F is fitted with a TEST button to ease the system global check.
The Omega-type external structure, protection IP20, occupies 9 modules when installed on the panel gets the same protection of the panel itself.
In addition to the alarm signal light, it is fitted with an internal buzzer.
