AJAX 10306 Transmitter Wired to Wireless Detector Converter - cover

Transmitter is a module for connecting third-party detectors to 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.

Transmitter is set up via a mobile application for iOS and Android based smartphones.

Operation procedure

Transmitter is designed to connect third-party wired sensors and devices to the Ajax security system. The integration module receives information about alarms and tamper activation through the wires connected to the clamps.
Transmitter can be used to connect panic and medical buttons, indoor and outdoor motion detectors, as well as opening, vibration, breaking, re, gas, leakage and others wired detectors.
The type of alarm is indicated in the settings of the Transmitter. The text of noti cations 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:

Type Icon
Intrusion alarm
Fire alarm
Medical alarm
Panic button
Gas concentration alarm

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

Connecting to the hub

Before starting connection:

  1. 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.
  2. Go to the Ajax application.
  3. Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).
  4. 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:

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

AJAX 10306 Transmitter Wired to Wireless Detector Converter - How to connect the Transmitter to the hub

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.

Unpair Device Disconnects the device from the hub and deletes its settings

Set the following parameters in the Transmitter settings:

  • The state of the external detector contact, which can be normally closed or normally open.
  • The type (mode) of the external detector that can be bistable or pulse.
  • The tamper mode, which can be normally closed or normally open.
  • The accelerometer-triggered alarm — you can turn this signal off or on.

Select the power mode for the external detector:

  • Turned off when the hub is disarmed — the module stops powering the external detector upon disarming and does not process signals from the
    ALARM terminal. When arming the detector, the power supply resumes, but the alarm signals are ignored for the
  • Always disabled — the Transmitter saves energy by turning off the power of the external detector. The signals from the ALARM terminal are processed both in the pulse and bistable modes.
  • Always active — this mode should be used if there are any problems in the “Turned off when the hub is disarmed”. When the security system is armed, signals from the ALARM terminal are processed no more than once in three minutes in the pulse mode. If the bistable mode is selected, such signals are processed instantly.

If the “Always active” operating mode is selected for the module, the external detector is powered only in the “Always active” or the “Turned off when the hub disarmed” mode, regardless of the security system status.

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).

Jeweller Signal Strength Test
Attenuation Test

Connection of the Module to the wired detectorа

Location of the Transmitter determines its remoteness from the hub and presence of any obstacles between the devices hindering the radio signal transmission: walls, inserted ge-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, move the device — even 20 cm shift can signiove 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.

  1. 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 type 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
2. 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.
