Smart socket and relays allow you to control and automate electric locks, gates, boilers, and other appliances using the Ajax apps


Our Relay supports several different relay modes of operation and various states of contact. They can be combined depending on user needs:

  • bistable, when the contacts close and open as a switch;
  • pulse, when the contacts close or open for 0.5 to 15 seconds, and then automatically execute the action in reverse.

To avoid accidents and equipment failures, we equipped our Relay mechanism with protection against overheating and voltage surges. It is permanently enabled and can’t be disabled. If the temperature where the Relay is installed exceeds 65°C, or 85°C inside the device, the relay opens and sends out an alarm. As soon as the temperature returns to normal, the relay releases and sends out the respective notification.

There are two threshold values for the supply voltage: the lower value is 6.5V, and the upper value is 36.5V. If the power level is too high or too low, protection is activated, the device is disabled and a warning message is sent out. After the supply voltage parameters return to normal, the relay releases and notifies users.

By default, the Hub is set to ping detectors every 36 seconds and to signal an alert after 30 undelivered pings. Under these settings, it will take about 18 minutes for the system to recognize a communication failure. You can adjust these settings by opening the app, going to the Hub Settings →Jeweller.

Currently, the following scenarios are available for Relay, WallSwitch and Socket:

In case of arming:

  • close the contacts (apply 230 V to the output)
  • to open contacts (stop feeding 230 V)
  • without action

In case of disarming:

  • close the contacts (apply 230 V to the output)
  • to open contacts (stop feeding 230 V)
  • without action

In additional Relay can react on arming/disarming in a pulse mode. The WallSwitch, Relay and Socket reaction is also available for “Night mode”.

Actions during the arming/disarming are independent. Any other automation scenarios now are under development.

The loop (zone) number is required to add a guarded facility to the CMS along with descriptions of all devices connected to the hub.

The loop (zone) number is available in the settings after activating the group mode in the Ajax application:

  1. Hub Settings Groups

Having selected a group, you will see a list of its devices. Each device has a Device No. (or DeviceIndex in Ajax PRO Desktop) that corresponds to the loop (zone) number. A number is assigned when a device is attached to the Hub. The first added device has the first loop (zone) number.

After a device or a detector is removed, its number will be assigned to the next added device. However, the numbering of other devices will not change.

In the Ajax app, select the «Devices» tab . Information about the firmware version and device ID is located at the very bottom of the tab with the device parameters.
