Updated March 22, 2021
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 protocol to the . It is not intended to use the device in
third-party systems.
Not compatible with the or
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 for iOS and Android based
smartphones.
Functional Elements
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
notications 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:

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:
Only users with administrative privileges can add the device to the hub
How to connect the Transmitter to the hub:
1. 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
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.
1. Select theAdd Deviceoption 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. SelectAdd— the countdown will begin.
4. 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.

By number of alarms — the device is
automatically disabled by the system when
the number of alarms is exceeded (specied

Unpair Device
Disconnects the device from the hub and

Set the following parameters in the Transmitter settings:
Select the power mode for the external detector:
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.

The state of the external detector contact, which can be normally closed or
normally open.
The type (mode) of the external detectorthat 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.
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 rst 8 seconds.
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.

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 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 oors, large-size objects located within the room.
Check the signal strength level at the installation location
Jeweller Signal Strength Test
Attenuation Test

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 signicantly 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.
