  • PS IN Terminals – “+” and “-” contact terminals, 7-24 V DC input power supply.
  • Relay Terminals – output potential-free terminals.

Operating Principle

Do not connect Relay power supply input terminals exceeding 36V or alternate current sources. It creates a risk or 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 7­24 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:

  1. Switch on the hub and check its Internet connection (the logo glows white or green).
  2. Install the Ajax app. Create the account, add the hub to the app, and create at least one room.
  3. Make sure that the hub is not armed, and it does not update by checking its status in the Ajax app.
  4. 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:

  1. Click Add device in the Ajax app.
  2. Name the device, scan it, or enter the QR Code manually (located on the case and packaging), select the room.
  3. Click Add — the countdown will begin.
  4. 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 its 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 6.5­36.5 V.Temperature Protection — The contact will be opened when the temperature threshold of 85° 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).Jeweller Signal Strength Test

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 the ReX radio signal range extender.

Installation Process:

  1. De-energize the cable to which Relay will be connected.
  2. Connect the grid wire to the Relay terminals according to the following scheme:

When installing Relay in the box, lead out the antenna and place it under the plastic frame of the socket. The bigger the distance between the antenna and metal structures, the lower the risk of interfering (and impairment) of the radio signal. 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:

  1. Outdoors.
  2. In metal wiring boxes and electrical panels.
  3. In places with temperature and humidity exceeding the permissible limits.
  4. Closer than 1 m to a hub.

Maintenance

The device does not require maintenance.
