FDnet – connecting Sinteso
•
Fault-protected FDnet - thus allowing the use of unshielded cables.
•
No additional power supply required for hooters and input/output modules.
The power for all elements is supplied by the FDnet and is protected against failure by
short-circuit disconnectors in the elements.
•
Simple migration of existing systems using T-taps in the FDnet.
•
Selectable detection behavior using application-specific sets of parameters with S-LINE
detectors.
•
Customized detector settings using customer-specific sets of parameters with S-LINE
detectors.
•
The alarm organization and alarm delay and fault delay functions are adjustable as with
SIGMASYS detectors.
12.6.1
Detector network:
•
126 address elements per FDnet (detection loop) can be connected
•
All types of cable can be used
•
Wires with a diameter of 0.28 mm
•
The detector network can be laid out in any form: ring, spur, ring with T-taps
It is recommended that you use:
•
Shielded fire alarm cable, e.g. IY (ST) Y at least 0.6 mmØ.
•
Unshielded twisted pair cable.
In the case of low interference environments, unshielded non-twisted pair cable such as NYM
can also be used. Here the maximum line capacity (500 nF) must be adhered to.
