Remote power supply control

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.

Lighting and electricity supply of a facility

Set up automatic shutoff of lights and selected sockets when arming your home, saving on electricity and reducing the risk of a short circuit.

Trustworthy video surveillance

Install a video surveillance system that does not compromise privacy - the cameras are powered only when the system is armed. Amd when the residents are at home, the cameras are de-engergized.

Underfloor heating

Set your floor heating or electric heaters to run by schedule and save money. And, if necessary, turn the equipment on and off remotely through the app.

Irrigation system

Create a schedule to automate sprinklers and control watering remotely through the app - even thousands of kilometers away.

Automatic gates / barrier

Control appliances via the app or using Button. No compromises in comfort and safety.

Site lighting

Set up a schedule for the external lights and their automatic activation by security system alarm. Along with street sirens, this is an effective protection against non-professional burglars.

Effect of presence

Simulate human presence in a cottage or a summer house - by turning on the lights, TV, or music by schedule.

Smart plug

Turn an ordianry socket into a smart device controlled via the app, wireless Button, and automation scenarios.

Features

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

Installation

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
