Before
attaching the AF-X Fireblocker connector, check
Ø
whether the cables have been connected to the disabled system isolating switch, and whether
the system isolating switch has been connected to the Fire extinguishing control panel correctly
and;
Ø
whether the electric circuit of the AF-X Fireblocker generators is intact with an ohmmeter with
an accuracy of at least 2.5%. The resistance must be between 1.3 and 3.2 Ohm.
ü
Any test current should not exceed 40 mA for a maximum of 300 seconds.
k)
Connect the power supply to the appropriate parts of the fire extinguishing system.
l)

Measures after activation of the extinguishing system
If the extinguishing panel activates the AF-X Fireblocker generators, the aerosol will present itself as a white cloud
that is rapidly dispersed from the unit. This aerosol cloud will enter into stable connections on a molecular level with
the free radicals that, as a catalyst, accelerate the fire reaction.
a)
If extinguishing is in progress, indicated by alarm signals of the control panel or otherwise audible or
visible, the protected area should be kept closed for a minimum of 30 minutes. Though longer is better, as
it will allow for heated materials to cool down to safe temperatures. Allowing air (with new free radicals)
to come into the protected area, might increase or restart the fire if temperatures are still (too) high.
b)
After extinguishing please contact your dealer immediately so that proper advice on the reconditioning and
restoring of the protected area and the fire extinguishing system can be followed directly.
c)
On the cleaning and reconditioning of the protected area after extinguishing more can be found in chapter
8, though it is always recommended to organize restoring and cleaning work of electronics or other delicate
equipment by specialized and trained organizations or staff.
