2.3 Components of the extinguisher system
Detection tube (Lifdes
TM
)
Warning!

The Lifdes
TM
pneumatic detection tube must not be damaged under any circumstances! It
must not be kinked or crushed! If this happens, the extinguisher system may not switch on in
case of fire, which could lead to serious damage to property and injury to persons.

Do not expose the Lifdes
TM
pneumatic detection tube within the machine tool to any direct
source of heat!
Note!
The pneumatic detection tube bears the inscription “
LIFDES
– do not cut kink crush “.
The heart of the extinguisher system is a special high-tech polymer tube.
It is positioned in the object to be protected according to the fire risk, and
is connected to the extinguisher cylinder via a valve, and is permanently
under pressure. It serves as a detection tube, i.e., as a linear sensor.
As soon as the ambient temperature rises above 110 °C, the tube will
burst. As a result, there is a pressure drop in the system and the valve of
the extinguisher container will open at virtually the same time.
Valve
The Sinorix
TM
al-deco STD extinguisher system is fitted with a specially
developed high-pressure valve. When the detection tube bursts, the
valve opens and starts the extinguishing procedure.
(See Chapter „5 What happens when there’s a fire?“)
.
DIMES
A DIMES (Digital Measuring System) is integrated into the valve. It
ensures the constant monitoring of the quantity of extinguisher in the
extinguisher container and passes this data on to the communication
interface.
The sensor also indicates the status of the extinguisher container via an
LED, as follows:
Filling level > 80% (green)
Technical alarm/fault (blinking red)
Extinguisher container empty or filing level < 80% (red)
Ball valve
A ball valve is fitted directly on the valve. This can be used to activate or
deactivate the extinguisher system
(see Chapter „3.3 Deactivating/
activating the system“)
. The position of the ball valve will be forwarded to
the Communication Interface.
The improper opening of the ball valve is prevented by a locking pin.
