Overview

Instant, dependable control for commercial and residential security installations. The AJAX SpaceControl two-way wireless key fob delivers immediate arm/disarm, night mode and panic alert capability so staff and tenants can react quickly during incidents.

The compact white transmitter runs on a standard CR2032 battery for extended operation and supports an industry-leading operating distance (up to 4,265') for flexible placement across large sites. Set up is fast through the iOS/Android app, and the device integrates with third-party central units via uartBridge or ocBridge Plus for streamlined access control and surveillance workflows. Ideal for installers, facility managers and security integrators looking to add verified remote control to alarm and monitoring systems — add AJAX SpaceControl to your security toolkit today.
