Ajax Relay

Low-current relay to control appliances remotely.

The impulse for smart security

• Flood-prevention system - Set the automatic water shut off in case the washing machine breaks or a pipe bursts. Control the water supply at the facility remotely or set up a schedule.
• Automatic gates / barrier - Control appliances via the app or using Button. No compromises in comfort and safety.
• Electric lock - Lock or unlock doors with the app or Button. Block access to premises by alarm or Night Mode activation and sleep calmly.
• Security smoke cannon - Set up the smoke cannon triggered by any detector alarm or DoubleButton hold-up device activation. Such a system reliably shelters people and valuables from burglars.
• Roller blinds / motorized curtains - Control the equipment remotely through the app, via Button, or set a scenario: when changing the security mode, according to the time of day, or by alarm activation.
• ACS blocking - Set up Access Control System (ACS) reader blocking when arming the system to prevent employee access the guarded premises and avoid false alarms.

Flexibility at the core

Settings versatility and low power consumption make Relay a universal tool for equipment control. Dry contact is not galvanically connected to the device power supply so that it can be used both in low-voltage and household networks. There are bistable and pulse modes. The relay can be easily connected to a power supply unit paired with a backup battery.

• Pulse 0.5–255 seconds
• Power supply 7–24 V DC
• Dry contact

No extra effort

Connecting Relay to the hub takes less than a minute — it's enough to scan a QR code with the Ajax app. The miniature device (39×33×18 mm) fits easily into a junction box, an electrical panel, or a switching unit body. And the flexible external antenna provides stable connectivity.

Always in touch

We developed the Jeweller radio protocol to ensure uninterrupted interaction of all security system devices. The radio protocol uses frames to synchronize device communication, authentication to prevent forgery, and encryption to protect against hacking.

• Two-way communication at a distance of up to 1000 meters
• 5 ReX radio signal range extenders in the system
• Command delivery in 0.15 s
• Adjustable ping from 12 s

Smart security for home and business

Use automation scenarios so your security system not only reports threats but also actively counters them.
