Metal box alarm with 4G module BP-AP512NGW

The power supply is DC15V/4A switching power
Use 12VDC, 7Ah sealed lead-acid battery, and replace it every 3-5 years.
A standard system with a keyboard power consumption of 180mA can support 24 hours.
When using without siren, connect a 2.2K resistor to clear the siren fault.
The total power supply demand of the keyboard, auxiliary power supply, siren, etc. does not exceed the maximum power of the host.
The maximum charging current of the battery is 350mA.
When using wired/bus defense zones, you need to set the defense zone attributes in the defense zone attribute settings.
