The GAS sensors connected to this equipment are of various types and must be positioned at different
heights depending on the type of gas to be detected.
These heights are:
- 30 cm. from the lowest point of the floor to detect:
heavy gases (G.P.L., etc.)
- 30 cm. from the highest point of the ceiling to detect:
light gases (Methane, Hydrogen etc.)
The probes must be selected with an "IP" degree of protection depending on the area to be
controlled (Kitchens, Boiler rooms, Laboratory, Factories, etc.) by choosing one of the probes
produced by Beinat that goes from IP30 to ATEX.
It is important to remember that the remote probes must be installed keeping in mind that:
1) The probes must not be installed near the appliance to be controlled, boiler, burner, industrial kitchens,
etc.) but on the opposite side.
2) The probes must not be affected by fumes, vapors, and by sources of moving air, which could distort
the detection.
3) The probes must not be installed near sources of heat, fans or vacuum cleaners.
NOTE. Recall that the GAS detection sensors placed inside the probe are perishable components, whose
average duration is variable 5 years therefore after this period it is good to replace them.
Maintenan ce
The user is kept periodically (every 6 months), to perform a verification of the operation of the detection
system by spraying specific test gas to the connected probes, until the alarm status of the control unit is
obtained.
a) Once a year, a more thorough check must be carried out by a specialized technician.
b) The removal of the probes after 5 years from installation must be carried out by qualified personnel.
