f)
De AF-X Fireblocker generators must be mounted in isolation (even if the Statement of Requirement does
not specify as such). Attach the mounting brackets, which need to comply with local rules and regulations,
to the wall, ceiling or other location, using the insulation glands and rings in all mounting holes that connect
the bracket to the mounting surface. Do this in such a way that the extinguishing units cannot move or get
damaged inadvertently.
g)
Take the AF-X Fireblocker from its packaging. Check the product for visible faults or damage as a result
of transport, etc. Take the AF-X Fireblocker from its packaging. Check the product for visible faults or
damage as a result of transport. Some generators are packed with nozzle protection brackets and
stickers. Remove them carefully and completely to assure the free outflow of aerosol during activation.
h)
The AF-X Fireblocker is delivered with a short circuit safety between the poles 1 and 2 of the female inlay
in the connector. This prevents unwanted currents in the activation unit. To assure a secure and safe
installation of the generator, please keep the short circuit safety as long as possible in its safeguarding
position.
i)
The cylindrical AF-X Fireblockers (Type CS and CM) are delivered with a protection cover on the nozzle.
After unpacking remove the protection cover.
j)
Check 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 6.1 and 7.5 Ohm.
The test current should not exceed 20 mA for a maximum of 300 seconds.
k)
Attach the AF-X Fireblocker firmly to the mounting brackets with the clasp and ensure an unobstructed
discharge. It is very important that there be no obstacle in the space immediately in front of the discharge
for a distance of at least the length of the AF-X Fireblocker generator itself (cf. drawing above). Always
maintain distance to cable ducts. Although the AF-X aerosol’s discharge temperature should not be
damaging to the cables, it is important that the discharge cannot be influenced. The correct distance at
which this unit must be installed is to be found on page 20 in annex 1.
l)
The MCU Monitoring and Control unit is specially developed for application at Kentec Sigma XT, AX-T or
the Honeywell Notifier RP1r-SURPA panels. The connection will be displayed in the image on page 9.
m)
Before
attaching the AF-X Fireblocker connector, check whether the cables have been connected to the
disabled maintenance switch correctly (red LED on the maintenance switch is on), and whether the
maintenance switch has been connected to the Fire extinguishing control panel correctly.
n)
Connect the power supply to the appropriate parts of the fire extinguishing system.
o)
Check whether the Fire extinguishing control panel functions properly.
p)
Check whether all requirements in this manual have been met.
q)
The final step is to switch the maintenance switch(es) to ‘on/active’ (red LED is off)
