The automatic fire alarm system is a type of building fire protection facility, consisting of two complete systems: fire detection alarm and fire linkage control 1. Check the manual button alarm, whether the alarm bells on this floor and its upper and lower floors sound, and whether the alarm area presented by the fire center is accurate 2. Thoroughly inspect the detector for compliance with regulations, and check the sensitivity of smoke and temperature detectors 3. Check whether the communication and control signals between each interface and the peripheral devices of the host system are in a normal state, and whether the output voltage of the interface is normal to ensure normal operation 4. The Pan Geo Remote Smoke Monitoring System is composed of three parts: front-end devices, user/server apps, and PC large screen terminals. Users can log in to the user app/PC to view the real-time operation status of the smoke sensor, and can also visually monitor the system's operation status on the large screen of the mobile phone. When a smoke alarm occurs, it can synchronously receive the alarm information and quickly respond to eliminate hidden dangers 5. Check the operation status of the working battery pack and charger, as well as check whether the voltage of the backup battery and other indicator parameters meet the requirements 6. Check whether the main control screen is in a normal state, whether the detector in a certain area is correctly displayed when an alarm signal source appears, and whether the alarm bell beeps normally 7. Check the system wiring for any looseness or detachment
