User Manual AF-X Fireblocker Nano Series version 3.5
Warning: the AF-X Fireblocker may only be installed, maintained or serviced by technically qualified
and trained persons and in accordance with the latest applicable local laws, regulations and
standards.
When working with the AF-X Fireblocker it is prohibitedto:
- open and/or dismantle extinguishing units;
- by any means apply force to the units that could result in distortion, physical or mechanical
damage to the casing;
- carry out welding activities in the vicinity of the AF-X Fireblocker extinguishing units;
- smoke in the vicinity of the AF-X Fireblocker extinguishing units.
In case an extinguishing unit has fallen, it should be checked for damage to the activator’s electric
switch and/or other components. When damage and/or dysfunction cannot be ruled out with
certainty, the unit cannot be used and must be returned to the authorised AF-X distributor or dealer.
Please see to it that all legal requirements, regulations and advice are adhered to. Pay attention
to the risks involved in working at height. Be careful of your footing and use reliable tools and
proper personal protective equipment. Should you have any queries, please consult your employer
and/or qualified consultancy agencies.
To avoid unnecessary exposure of occupants to the discharged extinguishant, factors such as the time
for egress and the risk to the occupants by the fire should be considered when determining the system
discharge time delay. Where national standards require other precautions, these should be implemented
5.0 Design and installation of a standalone system with one generator
A standalone AF-X Fireblocker generator can be activated by means of a thermal circuit. For this the AF-X Bimetal
Switch can be used. A standalone system cannot be larger than the max coverage volume of the generator.
Please note that equipment used for heating or welding, and other sources of energy, might provoke
activation of the fire extinguishing generator if the self-activation temperature is of 300 ºC will be reached.
5.1 Design and installation of a multiple generator system
The fire extinguishing system’s basic design determines which detection system and/or peripheral equipment will
be chosen. Please be aware that local rules and regulations or a certifying authority may require specific
equipment. For proper installation of the systems we expressly refer to the information in this DIOM and to the
Fire detection and fire alarm systems manufacturers installation requirements.
The minimum standard requirements for an aerosol fire extinguishing system with multiple extinguishing
generators are:
1. The Fire Extinguishing Control Panel FECP (whether or not connected to a Fire Alarm System, FAS) which
connects, supplies power to, monitors and controls the various components of the extinguishing system must
comply to CEN/TS 54-14, Fire detection and fire alarm systems - Part 14: Guidelines for planning, design,
installation, commissioning, use and maintenance or to similar local legislation, guidelines and / or standards;
2. The Fire Extinguishing Control Panel FECP must be able to provide sufficient energy to activate all the
generators in the system and as designed;
3. Unless otherwise specified in a standard, 72 h minimum standby sources of energy shall be used to provide
for operation of the detection, signalling, control and actuation requirements of the system.
4. Fire detection and fire alarm system must be able to generate acoustical and optical signals to warn or inform
people present in the protected area about the current status;
5. Wiring, components and connectors connecting the various parts of the system must meet the relevant part
of EN54 or similar.
