1.2 One Output Layout with Diversion Boxes: FG-DTC and FG-DTCS
In order to fit the complex installation, TTK offers two kinds of boxes: FG-DTC and FG-DTCS. They have
their own characteristics but both of them facilitate the extension of the system in different situation.
Layouts in session 1.2 explain different situations.
Digital Diversion Box: FG-DTC
The digital diversion box FG-DTC makes it possible to break up a detection circuit into two parts,
so as to allow the system to cover more horizontal spaces (figure 1.2).

● Use jumper cable for wall or corridor passage between two sensing cables. Maximum jumper cable length for
each FG-SYS output is 150 meter.

Extensive Density Protection
Typical ‘very important place’ extensive density protection, allowing perimeter and total floor coverage of the
room.
Typical application: mission critical facilities, data center,
hospital, expensive equipments/machines, UPS room,
etc.
Perimeter Protection
Typical and the most commun design for prevent external
liquid leak come inside the protected zone.
Sensing cable typically installed about 1 meter from the
walls.
Typical application: offices, archives room, kitchen, toilets, technical room, tank room, lift pit, etc.
Perimeter ACU Protection
Typical design for air-conditionners and leak possible
objects, prevent leaks extend without acknowledge.
Sensing cable typically installed about 75cm in front of
