AJAX Relay User Manual

Please note that deactivated device will save
it’s current state (active or inactive)
Unpair Device
Disconnect Relay from a hub and delete its
settings
Voltage protection — the contact will open when the voltage exceeds the limits
of 6.5–36.5 V.
Temperature protection — the contact will be opened when the temperature
threshold of 85°С inside Relay is reached.
Indication
The Relay light indicator can light green depending on the device status.
When not paired with the hub, the light indicator blinks periodically. When the
functional button is pressed, the light indicator lights up.
Functionality Testing
The Ajax security system allows conducting tests for checking the functionality
of connected devices.
The tests do not start immediately but within a period of 36 seconds when using
default settings. The test time start depends on the settings of the detector ping
interval (the Jeweller menu in the hub settings).
Installation of the Device
Regardless of the type of electrical circuit, only a qualified electrician should install
Relay.
