Ajax DoubleButton Jeweller White Wireless Hold-Up Panic Button

Ajax DoubleButton Jeweller White Wireless Panic Button

The Ajax DoubleButton is a dedicated wireless hold-up device designed for fast, discreet alarm activation in homes, offices, retail stores, and other commercial premises. Featuring two closely spaced buttons separated by a raised plastic divider, it is engineered specifically to prevent accidental triggers while still allowing a genuine emergency signal to be sent in seconds. Once pressed, the device communicates instantly and securely with an Ajax hub using the proprietary encrypted Jeweller radio protocol, alerting both app users and a connected monitoring station.

Key Features

• Dual-button design: Both buttons must be pressed together (short or long press over 2 seconds) to trigger an alarm, virtually eliminating false activations.
• Long wireless range: Communicates with the hub over a line-of-sight distance of up to 1300 metres, giving flexibility in placement.
• Encrypted Jeweller protocol: Two-way radio communication with block encryption and frequency hopping protects against jamming and signal interception.
• Durable, weatherproof housing: IP55-rated enclosure resists dust, splashes, and temperature extremes, suitable for a wide range of environments.
• Long battery life: Powered by a pre-installed CR2032 battery rated for up to 5 years of use with low-battery warnings sent via the Ajax app.
• Portable or fixed mounting: Can be clipped into an optional Holder for wall or under-desk mounting, or carried on a keychain, wrist strap, or lanyard.
• Automation triggers: Beyond raising an alarm, it can activate connected sirens, trigger automation scenarios, and integrate with other Ajax devices in the same ecosystem.
• Professional certification: Complies with EN 50131 (Grade 2), PD 6662:2017, UL, and ANSI/SIA CP-01 standards for commercial-grade security use.
• 24/7 operation: Remains active regardless of the security system's arm/disarm state, so an alarm can be raised at any time.

Ideal Applications

The DoubleButton is well suited to environments where a fast, silent call for help may be needed, such as cash registers in retail stores, bank counters, reception desks, warehouses, or bedrooms in a private home. Because it can be worn or carried, it also works well as a personal safety device for lone workers, elderly residents, or anyone who needs a discreet way to summon assistance without drawing attention to the situation.

Frequently Asked Questions

Does the DoubleButton require a separate mounting bracket?
Yes, the Holder used for wall or surface mounting is sold separately; the button can otherwise be carried loose using its built-in attachment hole.

Can it control other devices, like unlocking doors?
Its main job is raising alarms, but that alarm signal can also be configured to trigger connected sirens or automation actions such as unlocking doors or lowering shutters within an Ajax system.

Which hubs is it compatible with?
It works exclusively with Ajax hubs over the Jeweller radio protocol and is not compatible with third-party integration modules such as ocBridge Plus or uartBridge.
