Panic Button Ajax Button Wireless holdup alarm — battery CR2032, black

Ajax Button is a compact wireless panic and control button designed to send immediate alerts to an alarm monitoring company and system users. Powered by a single 3 V CR2032 battery and communicating over the Ajax wireless protocol, the black handheld Button supports multiple event types for incidents such as intrusions, gas leaks, fires or medical emergencies. It also controls smart-home scenarios via single, double or long presses, and is intended for personal safety, retail, hospitality and small business applications.

Advantages

The Button delivers data-rich alarms with event-specific codes and notification texts, ensuring accurate response by the monitoring station. Its design minimizes accidental activation and allows configuration for single-click, double-click or long-press actions. The device uses the Jeweller radio protocol with encrypted communication and automatic frequency switching to maintain alarm delivery across distances up to 1300 m in open space. Installation is simple: register the device via QR code in the Ajax app and mount or carry it as needed.

Suitable for

• Personal emergency alerts (medical or panic button)
• Retail and hospitality emergency signaling
• Remote triggering of security company patrols
• Smart-home control: lights, blinds, gates and appliances
• Small business closing/opening routines

When it may not be suitable

The Button is not a substitute for devices that require continuous medical monitoring or advanced biometric detection. Its wireless range and performance depend on the installation environment; heavy structural interference can reduce effective distance despite automatic frequency switching and encryption. For locations that need professional-grade medical telemetry or continuous two-way voice communication, choose specialised medical devices.

How to use

Register the Button in the Ajax app by scanning the QR code on the device, then choose mounting or carrying method: clip to keys, wear on a lanyard, or fix with double-sided tape.

For smart-home control, use the Button to activate predefined scenarios.

What to consider before purchase

• Confirm compatibility with your Ajax hub and system firmware
• Evaluate expected wireless range given building materials and layout
• Decide preferred activation mode (single, double or long press) to reduce false alarms
• Plan mounting or carrying method (clip, lanyard, adhesive) for intended use

Usage recommendations

Position the Button where it is quickly reachable during an emergency (near a bedside, at a shop entrance or on a keychain). Test communication and alarm delivery after installation and periodically check the CR2032 battery status in the Ajax app to ensure readiness.
