Due to the unique working principle of the heptafluoropropane gas fire suppression system, it must undergo regular inspections annually. How can one ensure that the heptafluoropropane fire suppression system is functioning properly? According to the "Code for Construction and Acceptance of Gas Fire Suppression Systems" GB50263-2007, a simulated start-up test should be conducted on each protected area once a year, as well as a simulated discharge test. However, in reality, if performed by non-professionals, the valuable heptafluoropropane agent could be quickly depleted during the test. Today, I will reveal the annual inspection methods for the heptafluoropropane gas fire suppression system.

Due toHeptafluoropropane Fire Extinguishing SystemThe uniqueness of the working principle necessitates regular inspections each year. So, how can one conduct inspections to ensure that the heptafluoropropane fire suppression system is functioning properly? According to the "Code for Construction and Acceptance of Gas Fire Suppression Systems."GB50263-2007 stipulates that each protected area should undergo one simulated start-up test and one simulated jet test annually. However, in reality, if performed by non-professionals, the valuable heptafluoropropane agent could be depleted in the test in no time. What should be done?Today, I'm here to share with you the annual inspection methods for the heptafluoropropane gas fire suppression system.

1. First, inspect the equipment's appearance.
Mainly for inspection:(1)Heptafluoropropane Gas Fire Extinguishing SystemAll equipment components are free from collision deformation and other mechanical damage; the surface is free from rust, and the protective coating is intact without blockages or loose fastenings; (2) there are no leakage phenomena in the pipeline and equipment, and there are no deformations, cracks, or aging in the connecting pipes, flexible hoses, and other pipelines; (3) the labels and signs are clear, and the protective covers, seals, and safety signs of the manual operation devices are intact; (4) inspect for any deformation, damage, rust, detachment, or loosening of the nozzle orifices, ensure the holes are unobstructed, and check for dust adhesions and blockages; if blockages are found, contact professionals for cleaning; (5) the wiring connections and instrument readings are normal.Heptafluoropropane Fire Extinguishing SystemVisual inspections are crucial not only for ensuring the system operates normally but also for guaranteeing the successful initiation of simulations and jet tests without any unintended spray. They must be conducted meticulously and with attention to detail.
2. Conducting simulation tests
Please note:Heptafluoropropane Fire Extinguishing SystemPrior to conducting all the following simulated jet tests, we must first shut off the electromagnetic drivers on the fire extinguisher storage containers and install the corresponding indicator lights, pressure gauges, or other devices.
01: During the simulation's automatic startup, we can bring lit cigarettes, incense sticks, etc. close to the smoke and temperature sensors within the test protected area to trigger simulated fire signals from them.
During simulated remote startups, manually operate the initiating device of the gas fire suppression system on the fire control equipment in the manual control room.
During the activation of the simulated emergency button, manually activate the emergency start button located outside the protected area.

In the above three simulated tests, it is necessary to observe whether the indicator lights are displaying normally, if the pressure gauge-measured pressure can drive the container valve and selector valve, whether the protective zone alarm device emits sound and light alarm signals, if the relevant fire-fighting equipment activates, and if the fire control equipment in the control room emits sound and light alarm signals with action signals from all parts.
04: Simulated Emergency Interruption. Inspection and Testing Method: Simulate fire signals within the protected area.(Or activate the emergency start button outside the protected area, or activate the emergency start device on the fire control equipment in the control room), within the 30-second delay time, activate the emergency shutdown button outside the protected area (or on the fire control equipment in the control room), and observe whether the gas fire suppression system operates and if the control room fire control equipment displays an emergency shutdown signal. Standard requirement: After the smoke and temperature detectors in the protected area alarm (or after the emergency start button outside the protected area is activated, or after the emergency start on the fire control equipment in the control room is activated), within the 30-second delay, manually operate the emergency shutdown button, the fire suppression command should be terminated, and the control room fire control equipment should display an emergency shutdown signal.
Annual inspections of the heptafluoropropane gas fire suppression systems are crucial; only thorough inspections can ensure the systems operate normally and reduce losses during fire incidents.
