Fire Alarm Cable

J-SH (St) SH FE180 E30 / E90 Fire Alarm Cable

Under fire conditions (below 750 ° C heat and flame) hard work condition (FE-180) can be maintained at 180 minutes, energy transmission, fire resistant cables are halogen free. These cables in the fire alarm system, fire equipment required to work in, the control cables of the elevator and machine, the power cable in fire alarm system connected to the ventilation system in the desired environment of corrosive gases are burned during cable fire in hospitals, schools and office centers, and so on. Used in place.

JE-H (St) H FE180 / E30 HFF Fire Alarm Cable

Industrial facilities, major hotels, hospitals, shopping centers, power plants, cultural centers, housing, airports, subway, as the large number of people, automatic control to ensure the continuation of current flow in the fire at the plant, in the security and fire alarm systems with analog and digital signals used in transmission. Such cables do not conduct flame during fire, smoke density is so low it does not create a favorable environment for corrosion and does not remove the toxic gases to affect human health.

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.
