TRANSMITTER USER GUIDE

The transmitter is a module used to link third-party sensors to an Ajax security system. It transmits alarm and warning signals when the tamper-proof mechanism of an external device is activated. It also has its own accelerometer to help protect the module from being removed. The module is battery-powered and can also power the connected device.

The transmitter is only connected to the Ajax secure system (it cannot be linked to third-party systems) using the Jeweler secure protocol, with a range of up to 1,600 meters in an unobstructed environment and not inside another device casing.

Connectivity with ocBridge and uartBridge integrated modules is not provided.

Transmitter is configured through an app available for iOS and Android.

The Ajax security system is capable of operating independently, but users can still link the system to the main monitoring centers of security companies.

2. Power connector from the battery.

3. LED signal lights

4. ON/OFF button.

5. Output: power, alarm signal, anti-tampering signal for the device.

Operating procedures

The transmitter device connects external alarm devices to the Ajax system: indoor and outdoor motion sensors, door opening sensors, vibration sensors, breakage sensors, fire sensors, gas leak sensors, etc. Compatible with sensors with NC/NO contacts.

The transmitter receives alarm information and activates the external detector's tampering button via the terminals. A pair of separate terminals ensures power is supplied to the external detector from the module's 3.3V battery.

Connect the sensor to the Hub.

Before starting the connection:

1. Install the Ajax app on your phone and follow the instructions to set up the Hub (Hub, Hub Plus).

2. Create a user account, add the Hub to the app, and create at least one room.

3. Open the Ajax application.

4. Turn on the hub and check your internet connection.

5. Check and make sure that the Hub is in the Disabled mode and not updating (check the status displayed in the application).

⚠️ Only users with administrator privileges can add new devices to the Hub.

How to connect a device to the Hub:

1. Select “Add device” in the Ajax app.

2. Name the motion sensor device, scan the QR code or manually enter the device's code into the app (the code is located under the lid and on the box), and select the Room for the device.
   

3. Turn on the device by pressing the small black button.

For the device to function effectively and without interference, the sensor must be placed within the wireless coverage area of ​​the Hub (with a protective object).

A request to connect to the Hub will be sent shortly after the device is powered on. If you are unable to connect to the Hub, try turning the device off and on again after 30 seconds.

Once connected, the transmitter will appear in the list of connected devices. The frequency of signal scanning will depend on the settings on the hub, with a default of 36 seconds.

Set the following parameters in the Transmitter settings:

• The state of the external detector contact can be normally closed or normally open.

• The type (mode) of the external detector can be blocked or pulsed.

• A dummy mode, which can be closed normally or opened normally.

• Acceleration trigger alarm - you can turn this signal on or off.

Select the power mode for the external detector:

• The Hub shuts off when deactivated - the module stops supplying power to the external detector when disabled and does not process alarm signals from the terminal. When the detector is reactivated, power is restored, but alarm signals are ignored for the first 8 seconds.

• Always disabled - The transmitter saves energy by shutting off the power to the external detector. Signals from the terminal are processed in both pulse and semi-stable modes.

• Always active - this mode should be used if there are any issues in the "Shut down when Hub is disabled" section. When the security system is equipped, signals from the ALARM terminal are processed no more than once every three minutes in pulse mode. If bistable mode is selected, those signals will be processed immediately.

If the "Always On" operating mode is selected for the module, the external detector will only be powered in "Always On" or "Off when Hub is deactivated" mode, regardless of the security system status.

Operation signal

Event	Signal
The module is enabled and registered.	The LED lights up when you press the ON button.
Registration failed	The LED flashes for 4 seconds with a 1-second interval, then flashes rapidly 3 times (and automatically switches OFF).
The module has been removed from the central device list.	The LED flashes for 1 minute with a 1-second interval, then flashes rapidly 3 times (and automatically switches to OFF).
The module has received an alarm/tampering signal.	The LED lights up for 1 second.
Out of battery	It gently lights up and turns off when the detector or tampering signal is triggered.

Check the touch screen.

The Ajax security system allows for testing to assess the functionality of connected devices.

The testing modes will not start immediately but after a 36-second cycle when using the default settings. The start time of the test depends on the scanning cycle settings of the sensor device (see the “Jeweller” settings in the Hub settings).

• Check signal strength

• Check for attenuation

Connect the module to the wired detector.

The transmitter's position is determined by its distance from the processing center and the presence of any obstacles between the devices that hinder radio signal transmission: walls, floor inserts, large objects in the room.

Check the signal strength level at the installation location.

If the signal level is only one bar, we cannot guarantee the stable operation of the security system. Take possible measures to improve signal quality! At a minimum, move the equipment – ​​even a 20 cm change can significantly improve reception quality.

If your device has a low or unstable signal strength, use a ReX radio range extender.

The transmitter should be placed inside the wired detector housing. The module requires a minimum space of the following dimensions: 110 x 41 x 24 mm. If installation inside the detector body is not possible, any available housing may be used.

1. Connect the transmitter to the detector via the NC/NO contacts (select the relevant settings in the application) and COM.
   
   The maximum cable length for connecting the sensor is 150 m (24 AWG twisted pair). This value may vary when using different cable types.

2. Function of the transmitter terminal

• + - — power output port (3.3 V)
  IMPORTANT! Do not connect an external power source to the generator's power output. This may damage the device.

• ALARM — Alarm signal gate

• TAMP — Vandal-Proof Signal Gateway

Protect the generator in its housing. Plastic mounting brackets are included in the installation kit. The generator should be installed on them.
