When the fire alarm or fault is handled, clean up the fire main engine. The operation method is to press the "reset" key and enter the user password to realize the reset function. The main function of resetting the fire main engine is as follows: clear all current fire alarms, faults and action displays.

Reset the status indicators on all bus control devices and manual fire-fighting startup disks, clear the commands that are being requested and delayed, and clear the mute state. Clear the isolation display, but the isolation marker light remains unchanged, and the isolation content still works. Enter the quarantine, cancel the quarantine operation, and the quarantine information will be displayed again.

Introduction to router network reset:

Sometimes you need to reset the router because you forget the password of the router or the password of the WiFi network. Resetting is a very simple matter, but many friends don't know how to reset the router after resetting.

Reset the setting parameters of the router instead of reinstalling it, so there is no line problem involved. You can directly enter the default gateway in the browser of the computer, and enter the default account information of the router in the pop-up interface to enter the management interface of the router. If the front-end device of the router is an optical cat, then a direct connection is enough.
