Frequently Asked Questions
The AJAX 6V PSU (type A) is designed for Hub 2, Hub 2 Plus, and ReX 2. It replaces the standard power supply module inside these devices to enable operation from portable battery sources instead of mains power.
The 6V PSU is specifically designed for zinc-air alkaline batteries with 4.2 - 10V output. We provide a list of recommended battery types that deliver optimal performance and longevity. Using incompatible batteries may damage the PSU or hub.
Yes. The 6V PSU should only be installed by qualified electricians. Installation requires opening the hub enclosure, disconnecting power, removing internal boards, and replacing the power supply module. Improper installation risks damage to the hub or personal injury.
Battery life depends on hub activity level and battery capacity. Zinc-air alkaline batteries typically provide 6 - 12 months of autonomous operation for normal security monitoring. We recommend checking battery status regularly via the Ajax app and replacing when voltage drops below acceptable levels.
The PSU has automatic switch-off voltage protection at 3 - 3.4V. When battery voltage drops below this threshold, the hub will shut down gracefully to prevent damage to components. The PSU will not operate below switch-on voltage of 4.2V ± 0.5%.
The PSU is an internal component and operates inside the hub enclosure. It's not exposed to weather. However, it operates reliably in up to 75% humidity and -10°C to +40°C temperature ranges when installed inside the hub.
Need Portable Power for Your AJAX Hub?
The AJAX 6V PSU enables autonomous operation of Hub 2, Hub 2 Plus, and ReX 2 from portable batteries. Perfect for remote locations, backup power scenarios, or temporary installations across Melbourne. Professional installation ensures optimal performance and reliability.
