In wired alarm systems, the quality of the cable used is critical for the stable operation and longevity of the system. Using low-quality or unsuitable cable can lead to signal loss, false alarms, and communication interruptions. Therefore, selecting the right cable for your alarm infrastructure is of paramount importance.
What cables are used in alarm systems?
Typically in alarm systems:
-
4×0.22 mm² alarm cable
-
6×0.22 mm² multi-core cable
-
Fire-resistant (halogen-free) cable
It is used.
The cable to be used is determined according to the number of sensors and the system structure.
What problems can a low-quality cable cause?
When using low-quality cables:
-
voltage drop
-
Signal attenuation
-
Noise (interference) generation
-
Random triggers
visible.
This increases the risk of false alarms.
Is cable quality more important over long distances?
Yes.
As the distance increases:
-
Signal loss may increase.
-
Resistance increases.
It is necessary to use high-quality cable with the appropriate cross-section.
This becomes even more critical in large areas, such as warehouses and factories.
Is Fire-Resistant Cable Necessary?
In businesses and large facilities:
-
Halogen-free
-
Flame retardant
cables should be preferred.
This reduces the formation of toxic gases in the event of a fire.
Interference and Electromagnetic Effects
Alarm cables:
-
Power cables should not be routed in parallel.
-
It should be kept away from high-voltage power lines.
Otherwise, electromagnetic interference may occur.
Does the cable's composition (copper quality) matter?
Yes.
Pure copper conductor:
-
Lower resistance
-
More stable signal transmission.
provides.
Copper-clad aluminum cables can reduce performance.
Risk of Failure in Wired Systems
In time:
-
Cable break
-
Oxidation
-
Loose connection
It may occur.
High-quality cabling and proper installation reduce the risk of malfunctions.
Is wired or wireless more secure?
Cable systems in large facilities:
-
It can offer a more stable infrastructure.
However, wireless systems are more practical for homes and small businesses.
Quality is important in both systems.
Is Installation Quality Important Too?
Yes.
Cable:
-
It should be drawn inside the pipe.
-
Joints should be insulated.
-
Connection points must be securely fastened.
Installation quality is just as critical as cable quality.
Why is cable quality more critical in workplaces?
In businesses:
-
There are many sensors.
-
The line distances are long.
-
The system is constantly active.
Therefore, the infrastructure must be robust.
