Xiao Bian talks to you about the problems that are easily existed in the automatic fire alarm system.
1, fire detectors (probes) extended service, domestic probe life is generally around 30,000 hours, (three and a half years), the world famous brand fire detectors up to 60,000 hours (seven years). However, after more than ten years in some building alarm systems, the probes are still not replaced, repaired, or cleaned. The sensitivity of the detectors cannot meet the needs of the work and the fire information obtained cannot be accurate. This may delay the alarm. The timing creates a disaster, which is a major fire hazard.
2. The automatic alarm system is inspected improperly. Some units cannot adhere to annual inspections, some test methods are not standardized, and test results lack reliability. (This type of responsibility testing unit should bear). Some units have perfunctory on the statutory annual inspection.
3. Some units are lax with the management of building fire protection facilities, and usually neglect the maintenance of the automatic alarm system. If problems arise, they cannot be repaired in time and run sick.
4. Some automatic alarm systems cannot be linked with fire-extinguishing systems and other fire-fighting facilities systems, and the function of fire-fighting facilities systems is flawed. This phenomenon is common in buildings in the late 1980s and 1990s.
5, some units fire control room usually on duty staff are insufficient, often one person a day, more than 12 hours of duty; less than two people in post. Do not fill in duty records.
6. There is a problem with the fire power supply, and it cannot be guaranteed that the automatic alarm system will automatically switch to continue working in the event of a power outage.
7. When the building fire-fighting facilities are upgraded or replaced, or when the equipment is updated, the design is unreasonable and it cannot be linked with other systems of the original equipment.
8, automatic alarm system to give up, do not apply for non-report, self-extinguishment. This situation is not small, it is a major fire hazard.
9, automatic alarm system did not establish a complete operating procedures, and do not follow the operating procedures to run, and some units do not guarantee the fire control room 24 hours monitoring, or even work to boot, off work.
