Application
As the unit is powered permanently, all wiring connections
must be made away from explosive atmospheres. The
unit should be grounded correctly to earth to avoid static
electricity issues.
As the unit housing contains aluminum, it is considered a
potential risk of ignition by impact or friction. Care must be
taken to prevent impact and friction during installation and
use.
The ambient temperature range is from -30°C (-22°F) to
80°C (175°F).
Conditions for installation and
maintenance
FG-STAD stands for "standalone alarm unit for hydrocarbon
leak detection sensors". This unit can be connected with one
hydrocarbon sensor only, and by TTK SAS.
This equipment can be installed in explosive atmospheres in
accordance with Directive 94/9/EC. The surface temperature
must not exceed the value shown below.
CAUTION
Please read all the instructions in this manual carefully
before installation. Do not start installation before reading
these instructions.
This equipment may receive some hazardous voltages.
Failure to read these instructions may lead to serious injury
or material damage. Before setting up the installation, check
that both the model and power supply suit your application.
This equipment must be wired in accordance with standard
practice by qualified staff.
INPUT SENSOR: This input will work only with a TTK
hydrocarbon detection sensor.

TTK’s FG-OD cables are certified ATEX / IECEx according to the marking mentioned above, according to EN / IEC 60079-0, EN / IEC 60079-18 and EN / IEC 80079-34.
Special installation precautions are required when working in explosive atmospheres, such as use of zener barriers, specific location of alarm and/or satellite panels etc.
The client is responsible for verifying that the design and installation of the detection system, in an ATEX / IECEx classified zone, is consistent with the classification of the area.
The client retains sole responsibility for its use of TTK’s products.

a. Discrete output.
Note: It is very important to follow the output circuit polarity as
shown below, with the positive (+) side of the circuit wired to the
CH1+/CH2+ terminal and the negative side (-) wired to the CMN
terminal. Otherwise, the output circuit will remain ACTIVE (or
CLOSED) regardless of the state of the output channel.
The discrete output of FG-STAD is driven by the unit and
designed to give an alarm signal.
Other faults: Leak and break sensor / bus simultaneous,
power supply lost.
