In a warehouse

Use the security system with visual alarm verification in buildings without mains voltage or with an unstable power supply. With a 12 V power supply you can connect hubs and signal amplifiers to low voltage or use a portable battery.

In a trailer

Ajax secures your home, even when it is on wheels. Connect the hub to a car or portable battery and let the security system travel with you.

On a boat / yacht

Insert a SIM card, connect the hub to the network or the battery on board and Ajax will ensure that your boat is safe at the pier.


The power supply board is compatible with the Hub 2 control panel. It has a standard connection for connecting the power plug and has an additional adapter connection (TA).


The 12 V power supply (PSU) is installed inside the device enclosure and replaces the pre-installed 110/230 V power supply.
