AJAX Hub 2 Plus User manual

Hub 2 Plus User Manual
Updated March 23, 2021
Hub 2 Plus is a central device in the Ajax security system, which controls the operation of all
connected devices and interacts with the user and the security company.
The hub reports the opening of doors, breaking of windows, threat of re or ood, and
automates routine actions using scenarios. If outsiders enter the secure room, Hub 2 Plus will
send photos from motion detectors and notify a security company patrol.
Hub 2 Plus central unit must be installed indoors only.
Hub 2 Plus needs Internet access to connect to the Ajax Cloud service. The central unit is
connected to the Internet via Ethernet, Wi-Fi, and two SIM cards (2G/3G/4G).
Connecting to Ajax Cloud is necessary for conguring and managing the system through Ajax
apps, transmitting notications about alarms and events, as well as for updating .
All data on Ajax Cloud is stored under multilevel protection, information is exchanged with the
hub via an encrypted channel.
Connect all communication channels to ensure a more reliable connection with Ajax Cloud and to secure
against interruptions in the work of telecom operators.
You can manage the security system and quickly respond to alarms and notications through
for iOS, Android, macOS, and Windows. The system allows you to choose of what events
and how to notify the user: by push notications, SMS, or calls.
If the system is connected to a security company, events and alarms will be transmitted to the
monitoring station — .

Operating principle
The hub monitors the security system operation by communicating with connected devices via
the . The communication range is up to 2000 m without obstacles
(for example, walls, doors, inter-oor constructions). If the detector is triggered, the system
raises the alarm in 0.15 seconds, activates the sirens, and noties the central monitoring station
of the security organization and the users.
If there is interference at the operating frequencies or when jamming is attempted, Ajax
switches to a free radio frequency and sends notications to the central monitoring station of
the security organization and to system users.
Hub 2 Plus supports up to 200 Ajax devices connected, which protect against intrusion, re, and
ooding, as well as control electrical appliances automatically according to scenarios or
manually from an app.
To send photos from motion detector, a separate Wings radio protocol and a
dedicated antenna are used. This ensures the delivery of visual alarm verication even with an
unstable signal level and interruptions in communication.
Hub 2 Plus is running under a real-time operating system OS Malevich. Similar OS control
spacecraft systems, ballistic missiles, and car brakes. OS Malevich expands the capabilities of
the security system, by air without user intervention.

Ajax account
The security system is congured and controlled through . Ajax applications are
available to professionals and users on iOS, Android, macOS, and Windows.
The settings of Ajax security system users and the parameters of connected devices are stored
locally on the hub and are inextricably linked with it. Changing the hub administrator does not
reset the settings of the connected devices.
To congure the system, install the Ajax app and . One phone number and
email address may be used to create only one Ajax account! There is no need to create a new
account for each hub — one account can manage multiple hubs.
Your account can combine two roles: the administrator of one hub and the user of another hub.

Detection Zone Test — running the detection zone test for the connected detectors. The
test determines the sucient distance for the detectors to register alarms.
What is Detection Zone Test

Jeweller — conguring the hub-detector ping interval. The settings determine how
frequently the hub communicates with devices and how quickly the loss of connection is
detected.
The time before raising the alarm by the communication loss between hub and device is
calculated with the following formula:
Ping interval * (number of undelivered packets + 1 correction packet).
The shorter ping interval (in seconds) means faster delivery of the events between the hub
and the connected devices; however, a short ping interval reduces the battery life. At the
same time, alarms are transmitted immediately regardless of the ping interval.
We do not recommend reducing the default settings of the ping period and interval.
Note that the interval limits the maximum number of connected devices:
Interval Connection limit
12 s 39 devices
24 s 79 devices
36 s 119 devices
48 s 159 devices
72 s 200 devices
Regardless of settings, the hub supports 10 connected sirens maximum!

Detector Ping Interval — the frequency of connected devices polling by the hub is
setting in the range of 12 to 300 s (36 s by default)
Number of undelivered packets to determine connection failure — a counter of
undelivered packets (8 packets by default).
Service is a group of hub service settings. These are divided into 2 groups: general settings
and advanced settings.

Installation
Prior to installing the hub, make sure that you have selected the optimal location and that it
complies with the requirements of this manual! It is desirable that the hub be hidden from direct
view.
Make sure that the communication between the hub and all connected devices is stable. If the
signal strength is low (a single bar), we cannot guarantee a stable operation of the security
system. Implement all potential measures to improve the signal quality! At the very least,
relocate the hub as even repositioning by 20 cm can signicantly improve the signal reception.
If low or unstable signal strength is still reported after relocation, use the
.
When installing and using the device, follow the general electrical safety regulations for using
electrical appliances, as well as the requirements of regulatory legal acts on electrical safety. It
is strictly forbidden to disassemble the device under voltage! Do not use the device with a
damaged power cable.
Hub installation:
Do not ip the hub when attaching vertically (for example, on a wall). When properly xed, the
Ajax logo can be read horizontally.
Do not place the hub:

We do not recommend using double-sided adhesive tape for installation: it can cause a hub to fall in
case of an impact.
2. Attach the hub to the mounting panel. After installation, check the tamper status in the Ajax
app and then the quality of the panel xation. You will receive a notication if an attempt is
made to tear the hub off the surface or remove it from the mounting panel.
3. Fix the hub on the SmartBracket panel with bundled screws.
