AJAX Transmitter Wireless Module

AJAX-Transmitter-Wireless-Module-product

The transmitter is a module for connecting third-party detectors to the Ajax security system. It transmits alarms and warns about the activation of the external detector tamper and it is equipped with own accelerometer, which protects it from dismounting. It runs on batteries and can supply power to the connected detector. Transmitter operates within the Ajax security system, by connecting via the protected Jeweller protocol to the hub It is not intended to use the device in third-party systems.

Not compatible with the uartBridge or ocBridge Plus
The communication range can be up to 1,600 meters provided that there are no obstacles and the case is removed.
The transmitter is set up via a mobile application for iOS and Android-based smartphones.

Operation procedure

The transmitter is designed to connect third-party wired sensors and devices to the Ajax security system. The integration module receives information about alarms and tampers activation through the wires connected to the clamps. Transmitters can be used to connect panic and medical buttons, indoor and outdoor motion detectors, as well as opening, vibration, breaking, are, gas, leakage and other wired detectors. The type of alarm is indicated in the settings of the Transmitter. The text of notifications about alarms and events of the connected device, as well as event codes transmitted to the central monitoring panel of the security company (CMS) depend on the selected type.

A total of 5 types of devices are available

The transmitter has 2 pairs of wired zones: alarm and tamper.
A separate pair of terminals ensure power supply to the external detector from the module batteries with 3.3 V.

Connecting to the hub

Before starting connection

Following the hub instruction recommendations, install the Ajax application on your smartphone. Create an account, add the hub to the application, and create at least one room.
Go to the Ajax application.
Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).
Ensure that the hub is disarmed and does not start updates by checking its status in the mobile application.

Only users with administrative privileges can add the device to the hub

How to connect the Transmitter to the hub

Select the Add Device option in the Ajax application.
Name the device, scan/write manually the QR Code (located on the body and packaging), and select the location room.
Select Add — the countdown will begin.
Switch on the device (by pressing on/off button for 3 seconds).

For the detection and interfacing to occur, the device should be located within the coverage area of the wireless network of the hub (at a single protected object). Request for connection to the hub is transmitted for a short time at the time of switching on the device. If the connection to the Ajax hub failed, the Transmitter will switch off after 6 seconds. You may repeat the connection attempt then. The Transmitter connected to the hub will appear in the list of devices of the hub in the application. Update of device statuses in the list depends on the device inquiry time set in the hub settings, with the default value – 36 seconds.

(displayed when the detector is in bistable mode only)

| Displays the status of the connected detector alarm zone. Two statuses are available:

OK — the state of the connected detector contacts is normal

Alert — the connected detector contacts are in alarm mode (closed if the type of contacts is normally open (NO); open if the type of contacts is normally closed (NC))

Alert if Moved

| It turns on the built-in accelerometer, detecting device movement

Always Active

| When this option is enabled, the integration module is constantly armed and notifies about the connected detector alarms

Detector power supply

| 3.3 V power-on for wired detector:

Always enabled — use if problems are observed in the “Disabled if hub is not armed” power mode of the external detector. If the security system is armed in pulse mode, signals on the ALARM terminal are processed no more than once every three minutes and always processed in the bistable mode.

Disabled if disarmed — the module powers off the external detector if disarmed and does not process signals from the ALARM terminal.

Once the detector is armed, the power supply resumes, but the detector alarms are ignored for the first 8 seconds.

Always Disabled — Transmitter does not use energy to power an external detector. Signals from the ALARM terminal are processed in both pulse and bistable modes.

If the Always Active mode is enabled, the external detector power supply is on in the Always Active or Disabled if not Armed modes only, regardless of the security system status.

How to set Chime

Chime is a sound signal that indicates the triggering of the opening detectors when the system is disarmed. The feature is used, for example, in stores, to notify employees that someone has entered the building. Notifications are configured in two stages: setting up opening detectors and setting up sirens.

Learn more about Chime

Transmitter settings

Before setting up the Chime feature, make sure that a wired opening detector is connected to Transmitter and the following options have been configured in the detector settings in the Ajax app:

Detector power supply
External Detector Contact Status
External Detector Type
Type of event
Tamper status

Go to the Devices – menu.
Select the Transmitter.
Go to its settings by clicking the gear icon in the upper right corner.
Go to the Chime Settings menu.
Select siren notification for the event If external contact is open.
Select the chime sound: 1 to 4 beeps. Once selected, the Ajax app will play the sound.
Click Back to save the settings.
Set up the required siren.

Performance testing

The Ajax security system allows conducting tests for checking the functionality of connected devices. The tests do not start straight away but within a period of 36 seconds when using the standard settings. The test time start depends on the settings of the detector scanning period (the paragraph on “Jeweller” settings in hub settings).

Jeweler Signal Strength Test
Attenuation Test

Connection of the Module to the wired detector

The location of the Transmitter determines its remoteness from the hub and the presence of any obstacles between the devices hindering the radio signal transmission: walls, inserted doors, or large-size objects located within the room.

Check the signal strength level at the installation location

If the signal level is one division, we cannot guarantee stable operation of the security system. Take possible measures to improve the quality of the signal! As a minimum, moving the device — even a 20 cm shift can significantly improve the quality of reception.

If, after moving, the device still has a low or unstable signal strength, use a radio signal range extender ReX.

The Transmitter should be encased inside the wired detector case. The Module requires a space with the following minimum dimensions: 110 × 41 × 24 mm. If the installation of the Transmitter within the detector case is impossible, then any available radiotransparent case could be used.

Connect the Transmitter to the detector through the NC/NO contacts (choose the relevant setting in the application) and COM.

The maximum cable length for connecting the sensor is 150 m (24 AWG twisted pair).
The value may vary when using different types of cable.

The function of the Transmitter’s terminals

+ — : power supply output (3.3 V)
ALARM: alarm terminals
TAMP: tamper terminals

IMPORTANT: Do not connect external power to the Transmitter’s power outputs. This may damage the device.

Secure the Transmitter in the case. Plastic bars are included in the installation kit. It is recommendable to install the Transmitter on them.

Do not install the Transmitter

Near metal objects and mirrors (they can shield the radio signal and lead to its attenuation).
Closer than 1 meter to a hub.

Maintenance and Battery Replacement

The device does not require maintenance when mounted in the housing of a wired sensor.
