I. Overview

YX-ZD optical fiber sensing alarm device (vibration cable, optical fiber alarm, vibration optical fiber or optical fiber perimeter for short) is a proprietary perimeter alarm system independently developed by the Company. Using optical cable as the sensing detection unit, the system can realize highly sensitive, long-perimeter and wide-range protection. It’s widely applied in government, petroleum, chemical engineering, water conservancy and military affairs fields, and in prisons, airports, railways, highways, mine lots, power plants, cultural relics and historic sites, scenic spots, schools, villas and high-end residential communities.

II. Key Features:

1. Patented Product: In response to traditional products prone to weather-caused false alarms or alarm failures, the Company has developed an equivalent weatherproof false alarm/alarm failure-proof product (weatherproof detector) certified as national patents numbered 200920043335.6, 201120165688.0, 201120179989.9 and 201120179990.1. Automatically shielding off the interference of the weather on the perimeter through hardware, the product has overcome the worldwide problem of weather-caused system false alarm. Counterfeiting will be held responsible.

2. Wide Range: The host machine can cover 35 defense areas, each of which maximally extends for 1 km. Each host machine can detect within a radius of 36 km. Accommodating infinitely extended host machines, the system can truly realize overall wide-range and long-perimeter protection.

3. Passive Defense Areas: Adopting monomode optical fiber as detection unit, the system realizes passive defense areas outdoors and effectively prevents interference of thunder and lightning. It´s particularly applicable for such inflammable, explosive and strong electromagnetic interference venues as oil depots, power stations, arsenals, airports and high-speed rails.

4. Good Applicability: As optical fiber is unrestricted by perimeter media, terrain, environment and other factors, the system is especially applicable for regions without media or with irregular, varying media, hostile environment and complicated geography.

5. Convenient Installation: The optical cable can be directly laid on perimeter media like wire entanglements, iron fences and walls, saving the trouble of digging cable ducts and greatly reducing installation fees and time.

6. Good Compatibility: As the frontend equipment of Internet of Things, the product has been designed with multiple data connection ports compatible with other integrated platforms like other alarm host machines, digital matrix, DVR, NVR, on-site sound-light alarm to realize data connection and system linkage. The host machine won’t affect the response speed of the whole system because of linkage.  

7. Service Life: As the outdoor service life of optical cables up to national standard is 20 years, the whole system offers long service life, stable performance and low maintenance cost.

8. Energy-saving and Eco-friendly: Realizing no-copper informationalization, the system only consumes 60W to 80W of electricity per 100 kilometers.
