Fogmaker Universal
7. Measures in the Event of Fire
The following measures should be taken in case there is a fire in the protected room:
1. Stop engines and ventilators
2. Turn off the electricity
3. Shut, if possible, the doors/hatches to the room
4. Activate Fogmaker Universal
If the system is not fully automatic or if it is in manual mode:
Use the pull-cable(s) or press the release button
5. Shut down the fuel supply to the engine
6. If possible, keep the protected room closed for five minutes after extinction.
You should have a hand-held extinguisher prepared, if the fire should flare up again.
8 Measures after Extinction
Fogmaker Universal contains an anti-freeze agent, a corrosion inhibitor and a film-forming liquid
(which is decomposed by nature's own organisms). However, when the extinguishant dries up, the
corrosion inhibitor loses its effect. In order to avoid corrosion, you should clean any metal parts as soon
as possible after the system has been discharged. This is done by rinsing the equipment with fresh water,
preferably using a high-pressure washer. We also recommend that you use an alkaline detergent, to
facilitate the removal of the film-forming chemical. If this is not done properly, any remaining film
may gather dust and dirt.
In order to protect the engine, electrical fittings and other metal parts from corrosion, you should
wash away any remains of dried or damp extinguishant as soon as possible after the extinguisher
has been discharged (preferably using a high-pressure washer). This should always be done,
whether the extinguisher has been activated in connection with a fire or for any other reason.

2. Release Valve
WARNING
When the safety screw (7) and the protective cover (17) have been removed, Fogmaker
Universal can be accidentally activated by a slight pressure to the release catch which is located
under the protective cover (16). The release valve must not be dismantled if the cylinder is
pressurized. If the valve or any of its nipples are removed when the cylinder is under pressure a
liquid jet, strong enough to injure a person seriously, will be discharged.
2.1 Release Valve (Fig. 2A, 2B)
Fogmaker Universal can be activated manually, electrically from a control panel, or automatically
through a detector circuit, see Fig 2A. The valve could also be automatically activated using a pneumatic
device (Firetrace), see Fig. 2B.
Fogmaker International AB provide a range of central units – manual, semi-automatic or fully
automatic - which can be used to control the electrical release device. Contact your retailer for further
information.
The release valve (4) is attached to the lid of the cylinder (15). The valve has an outlet opening (5) for
the extinguishant. For security reasons the outlet is equipped with a safety plug, which should always be
inserted before you service or transport a pressurized cylinder. There are two sockets for pull-cables
(13). The valve is secured from accidental activation by a safety screw (7), which should always be in
place when servicing or installing/dismantling the extinguisher and when transporting a pressurized
cylinder. Electrical activation connector cables (9). Two protective covers (16 and 17) will prevent dirt
from affecting the function of the release mechanism. The safety screw should be removed when the
cylinder has been installed and you want to take the extinguishing system into operation. At all other
times the safety screw should be mounted, in order to prevent unintentional activation. Keep the safety
screw hanging by the wire (18) when you have unfastened it.
Fig 2B displays the fully automatic pneumatic valve and the connector for the pneumatic hose (18).
Pneumatic detection can not be combined with pull-cables. For mechanical activation of Firetrace, see
section 3.
2.2 Valve Hose
The valve outlet and the sprinkler system
are connected through a valve hose. This
hose is designed to absorb vibrations and
thereby prevent vibration damage to the
pipes.
