Module for connecting wired alarm to Ajax & managing security via the app

Opting for Ajax during renovations allows you to retain your existing equipment rather than replacing it. This presents an opportunity to establish a modern, sophisticated security system by integrating new elements alongside your current wired setup.

Integration module with 18 wired zones for connecting third party detectors to Ajax. Perimeter IR detectors, household gas sensors, thermostats, float sensors, and various other devices are poised to broaden the scope of Ajax applications.
