Fire Detection and Alarm Systems Issues to be Considered in Cabling
One of the most important reasons for not working as expected of a fire detection and alarm system wiring is done correctly and properly. Wiring in the assembly phase of design should be very careful about the following points.
– The zone where the detector (fire department) cables must be selected according to the manufacturer’s recommendation.
– The cable section must be calculated.
– Manufacturer zones (fire department) must be complied with in length.
– Cable load calculations must be performed.
– Connections must be made resistant manner and accurately.
– Cable routing should be selected so that it can be managed.
– It should not be water or very high humidity in the cable route. If the cable must be used in accordance with these terms.
– Cable shielding, standards and regulations must be grounded properly.
