How to calculate the number of connectable detectors (in progress)
For facilities that are under construction or renovation, cables are laid after the
main wiring of the facility. Use special protective tubes to route system cables
to organize and secure them; special ties, clips, and staples can be used to
secure the cables.
When laying cables externally (without mounting them inside the walls), use an
electric channel raceway. Raceways should be no more than half- lled with
cables. Do not allow cables to sag. The raceway should be hidden from view if
possible — for example, behind furniture.
We recommend laying cables inside walls, oors, and ceilings. This will provide greater
security: the cables will not be visible, and it will be impossible for an intruder to access
them.
When selecting a cable, consider the length of the connection lines and the
number of detectors to be connected; these parameters affect the signal
strength. We recommend using shielded copper cables with a high-quality
insulation layer.
When installing, observe the bend radius that the manufacturer speci es in the
cable specs. Otherwise, you risk damaging or breaking the conductor.
Be sure to check all cables for bends and physical damage before installation.
Perform the installation in a way that minimizes the possibility of damage to the
cables from the outside.
Signal strength and cable length
The Fibra signal level is determined by the number of undelivered or corrupted
data packages over a certain period. The icon
