1、 Installation and deployment precautions

1. Reasonable site selection
   • Avoid interference sourcesStay away from strong electromagnetic interference sources such as high-power motors, frequency converters, and wireless transmission equipment to prevent false alarms or signal interruptions.
   • environmental adaptabilityThe installation location should be dry, ventilated, and avoid high temperatures (such as boiler rooms), humidity (such as bathrooms), or corrosive gas environments to prevent equipment aging or short circuits.
   • Protection levelChoose the protection level according to the environment, and provide a rain cover for outdoor installation.
2. Wiring specifications
   • dedicated lineThe power and signal lines of the alarm system should be laid independently to avoid mixing with power cables and reduce electromagnetic interference.
   • Wire diameter matchingChoose the appropriate wire diameter based on the device power to prevent overheating caused by line overload.
   • Reserved marginThe length of the line needs to consider future expansion needs to avoid difficulties in system renovation due to insufficient lines.
3. grounding protection
   • Equipment groundingEnsure reliable grounding of alarm hosts, detectors, and other equipment to prevent damage from lightning strikes or static electricity.
   • Equipotential bondingInstall equipotential terminal boxes inside buildings to connect metal pipes, equipment casings, etc., reducing sparks caused by potential differences.

2、 Daily usage precautions

1. Prohibit arbitrary modifications
   • Lines and equipmentNon professionals are not allowed to modify the circuit, replace detector types, or adjust alarm thresholds without authorization to prevent system failure.
   • Alarm SettingsIt is strictly prohibited to turn off the alarm function or reduce sensitivity, ensuring that the system can respond promptly in case of abnormalities.
2. Avoid misoperation
   • Test SpecificationDuring regular testing, specialized testing tools (such as simulated leakage generators) should be used to avoid direct short circuiting of the circuit and equipment damage.
   • Reset operationAfter the alarm, it is necessary to first investigate the cause of the fault, confirm safety, and then reset the system to prevent repeated alarms or fire hazards.
3. External Device Management
   • Linked devicesIf the system is linked to a fire extinguishing device (such as gas fire extinguishing), it is necessary to regularly check whether the linkage function is normal to prevent accidental spraying.
   • communication equipmentEnsure smooth communication between the alarm host, fire control room, and monitoring platform to avoid signal interruption.

3、 Maintenance and upkeep precautions

1. regular testing
   • Detector cleaningClean the surface dust of the detector with a soft bristled brush every month to prevent dust accumulation from affecting sensitivity.
   • Functional testingSimulate faults such as leakage and overload every quarter, test whether the alarm host sends out sound and light signals in a timely manner and cuts off the power supply.
   • Battery inspectionIf using a backup battery, it is necessary to check the power level every six months to ensure that the system can continue to operate in the event of a power outage.
2. Calibration and Update
   • parameter calibrationEvery year, a professional organization calibrates the sensitivity of the detector to ensure that the alarm threshold meets the standard (such as the leakage alarm value, which is usually 300mA-500mA).
   • software upgradeTimely update system software, fix known vulnerabilities, and optimize functionality (such as adding self diagnostic capabilities).
3. Fault handling
   • Common FaultsIf there are false alarms, missed alarms, communication interruptions, etc., it is necessary to first check the line connection and detector status, and then troubleshoot power or software issues.
   • Spare Parts ManagementReserve commonly used spare parts (such as detectors and modules) to ensure quick replacement in case of malfunction.

4、 Personnel training and emergency management

1. Operation Training
   • userProvide system operation training for duty personnel, electricians, etc., to master alarm handling procedures, equipment reset methods, etc.
   • emergency drillRegularly organize fire emergency drills, simulate scenarios such as alarm, evacuation, and firefighting, and enhance personnel response capabilities.
2. Record and Archive
   • Maintenance RecordDetailed records of the time, content, and results of each inspection, calibration, and repair for easy traceability and management.
   • fault recordEstablish a fault file, analyze the causes of frequent alarms (such as line aging and improper equipment selection), and optimize system design.
