AJAX 000169 12V Wireless Dry Contact Power Relay User Manual
Relay is a wireless, low-
voltage relay featuring potential-free (dry) contacts. Use Relay to remotely
switch on/off appliances powered by a 7–24 V DC source. Relay can operate both
in pulse and bistable mode. The device communicates with a hub via
Jeweller radio protocol. In the line of
sight, the communication distance is up to 1,000 m.
Regardless of the type of electrical circuit, only a qualified electrician should install Relay!
The Relay contacts are not galvanically connected to the device itself, so they can be connected to the input control circuits of various equipment to imitate a button, toggle switch, etc.
Relay is compatible only with Ajax hubs
and does not support connecting via
uartBridge or . Jeweller
ocBridge Plus
Use scenarios to program actions of automation
device (Relay, Wall Switch or
Socket) in response to an alarm,
Button press or schedule. A scenario
can be created remotely in the Ajax app.
How to create and configure a scenario in the Ajax security system
The Ajax security system can be connected to the central monitoring station of a security company.
Functional Elements

- Power supply terminal block
- Contacts terminal block
- Function button
- Light indicator
Operating Principle
- PS IN terminals — “+” and “-” contact terminals, 7-24 V DC input power supply.
- Relay terminals — output potential-free terminals.
Do not connect Relay power supply input terminals to a voltage exceeding 36 V or alternate current sources. It creates a risk of fire and will damage the device!
Regardless of the type of electrical circuit, only a qualified electrician should install Relay
Relay is powered by a 7–24 V DC source. The recommended voltage values are 12 V, and 24 V. Use the Ajax Security System app to connect and set up Relay.
Relay features dry (potential-free) contacts. The contacts are not connected to the device galvanically so that Relay can imitate a button, switch, etc. in electrical circuits of various voltages (sirens, electrical valves, electromagnetic locks). The miniature body makes it possible to install Relay inside a junction box, switchboard, or a switch.
Relay closes and opens the contacts by user command from the app or automatically by scenario.
Relay operation modes
- Bistable — Relay opens or closes contact and remains in this state.
- Pulse — Relay opens or closes contacts for a pre-set time (from 0.5 to 255 seconds) then switches back to the initial state.
Connecting to the hub
Before connecting the device:
-
Switch on the hub and check its Internet connection (the logo glows white or green).
-
Install the . Create the account, add the hub to the app, and create at least one room.
Ajax app -
Make sure that the hub is not armed, and it does not update by checking its status in the Ajax app.
-
Connect Relay to 12 or 24 V power supply.
Only users with administrator rights can add a device to the app
To pair Relay with a hub
-
Click Add device in the Ajax app.
-
Name the device, scan it, or enter the QR code manually (located on the case and packaging), select the room.
-
Click Add — the countdown will begin.
-
Press the functional button.
For detection and pairing to occur, the device should be located in the coverage area of the hub’s wireless network (at the same object). The connection request is transmitted only at the moment of switching on the device.
If the device failed to pair, wait 30 seconds and then retry. Relay will
appear in the list of hub devices.
The device statuses update depends on the ping interval set in the hub
settings.
The default value is 36 seconds.
When switching on for the first time, Relay contacts are open! When deleting Relay from the system, contacts open!

Temporary Deactivation| Allows a user to deactivate the device without
removing it from the system. The device will not execute system commands and
participate in automation scenarios. All notifications and alarms will be
ignored
| 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
The communication range with the hub in the line of sight is up to 1,000
meters.
Take this into account when choosing the location for Relay.
If the device has a low or unstable signal strength, use a radio signal range ectender.
Installation process
- De-energize the cable to which Relay will be connected.
- Connect the grid wire to the Relay terminals according to the following scheme:
Do not shorten the antenna! Its length is optimal for operation within the used radio frequency range
During the installation and operation of Relay, follow the general electrical
safety rules and the requirements of electrical safety regulatory acts.
It is strictly forbidden to disassemble the device. Do not use the device with
damaged power cables.
Do not install the relay:
- Outdoors.
- In metal wiring boxes and electrical panels.
- In places with temperature and humidity exceeding the permissible limits.
- Closer than 1 m to a hub
Maintenance
The device does not require maintenance.
