8. Restart - the button restarts the device. Hold the button for 2 seconds and release, the system will restart.
9. Activity - green LED shows the device system status.
   
   Device operating mode: blinks twice per second; successful software update completion: blinks four times per second.
   
   Error - red LED indicates errors and traffic.
   
   Device operating mode: if everything is normal, the LED is off; if not, there is a steady light.
   
   Software update mode: blinks twice per second;
   
   Alarm - the LED can be programmed from the user interface for alarm display.
10. TEMPERATURE SENSOR - Accuracy +/- 1 °C.
11. E1, E2 - LED status indicators for 12V 0.25A relay outputs.
    
    R1, R2 - LED status indicators for x2 NC/NO/COM relays.
    CAN - green LED shows the CAN bus status.
12. DRY CONTACT INPUTS 1...16 - Digital inputs (Type IN).
13. Expansion slot - Only one of the two expansions can be installed: "Modbus RTU extension" or "OSDP v2 reader extension". Must be ordered separately.
14. Case grounding - Case grounding, M4 thread.
    
    Improves equipment immunity against conducted and radiated RF interference. Please contact a professional electrician before connecting.
15. Battery expansion slot - Battery backup expansion can be installed in this slot. The expansion must be ordered separately.
16. RESERVE - Reserve power input. 100-240VAC, 50/60Hz, fuse 2A, fuse 5x20mm, type C14.
17. MAIN - Power input. 100-240VAC, 50/60Hz, fuse 2A, fuse 5x20mm, type C14.
18. Relay 1, Relay 2 - NC/NO/COM power relay connections.
    
    The LED is ON (orange) - the relay is ON (initial state can be configured).
    The LED is OFF (orange) - the output is OFF (initial state can be configured).
19. OUTPUTS 12V 0.25A - 12V 0.25A (for each output) connection outputs (electronic relay). LED indicators are located on the front panel.
    
    The LED is ON (orange) - the output is ON (initial state can be configured).
    The LED is OFF (orange) - the output is OFF (initial state can be configured).
20. Factory reset - Reset settings to factory defaults.
    
    Hold the button for more than 5 seconds. The error LED begins to blink. This indicates the factory restore has started. Wait 20-60 seconds until the system restarts.
    The activity LED starts blinking as soon as the system restarts. The device can now be accessed.
21. N - R - DIP switch used for various system modes.
    
    Normal mode: switch is toggled to the left ←. The switch should always be in this position.
    Device recovery: switch is toggled to the right →. Used to load the clean system image from an SD card.
22. SD card - MicroSD card slot with eject. The card is required for data storage or system recovery.
23. DC 12V BACKUP POWER SUPPLY - This is a third backup option. The board has three power lines.
