AJAX AJ-TRANSMITTER Transmitter User Manual

Transmitter User Manual

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.
The communication range can be up to 1,600 meters provided that there are no obstacles and the case is removed.

Functional Elements

QR code with the device registration key.
Batteries contacts.
LED indicator.
ON/OFF button.
Terminals for detector power supply, alarm and tamper signals.

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, fire, gas, leakage and others wired detectors.

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

Following the hub instruction recommendations, install the on your smartphone. Create an account, add the hub to the application, and create at least one room. Ajax application
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.

States

The states screen contains information about the device and its current parameters. The statuses of Transmitter and the device connected to it can be found in the Ajax app:

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

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.

Indication

Event	Indication

The Module is switched on and registered

| The LED lights up when the ON button is briefly pressed.

Registration failed

| LED blinks for 4 seconds with an interval of 1 second, then blinks 3 times rapidly (and automatically switches OFF).

The Module is deleted from the list of hub devices

| LED blinks for 1 minute with an interval of 1 second, then blinks 3 times rapidly (and automatically switches OFF).
The Module has received alarm/tamper signal| The LED lights up for 1 second.

Batteries are discharged

| Smoothly lights up and goes out when the detector or tamper is activated.

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).

Connection of the Module to the wired detector

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 floors, 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, move the device — even 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
.
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.

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.
