Frequently Asked Questions

AJAX alarm system keypad plus
AJAX alarm system Front side view

What can I do with my Ajax alarm system?

Ajax alarm systems can be easily extended to include intrusion, fire and flood detectors, as well as relays for remote management of electrical appliances. Additional devices can be purchased separately and added to the alarm system. Detectors can be connected using a few buttons on the mobile app.

Ajax Hubs

Do AJAX alarms really work so far away from the hub?

We've tested the maximum distance between the hub and the opening sensors, and it really is 2000 meters. Your experience may vary, as walls, ceilings and other barriers will reduce this distance. If you're not sure, you can do a radio test using the Ajax Security System App to determine signal strength before installing the detectors.
