Ajax Hub 2 (4G) Jeweller

Overview

The Ajax Hub 2 (4G) Jeweller is the control panel of an Ajax wireless alarm for a home, shop or office. It links detectors, keypads and sirens by radio, sends alarms to your phone through the Ajax app or to a monitoring company, and shows photos from MotionCam detectors so you can see what set off the alarm. It stays in touch over Ethernet and two 4G SIM cards, and keeps running on its own battery during a power cut.

Is it right for you?

• It suits a home, shop or office that needs up to 100 Ajax devices, 50 users, 9 security groups and 50 rooms.
• Choose it if you want photo verification: it receives MotionCam photos over the Wings radio protocol.
• It is for indoor use only (IP20, -10 to 40 °C).
• You need an Ethernet port, a mobile signal, or both, at the place you fit it.
• If voice calls over 4G (VoLTE) matter to you, note that the hub does not support them.

Key features

• Up to 100 Ajax devices, including up to 10 sirens or keypads with a built-in siren and up to 5 range extenders.
• Jeweller radio range up to 2,000 m and Wings up to 1,700 m in open space, so detectors can sit across a large home or building.
• Three communication channels: Ethernet up to 100 Mbps and two micro-SIM slots for 2G, 3G and 4G (LTE). Switching from Ethernet to SIM is instant; between SIMs takes up to 4 minutes.
• Photo verification by alarm, by scenario, on demand and by schedule, with photos up to 640 × 480 pixels, 1 to 5 photos per series, delivered in up to 9 s by default.
• Up to 25 IP cameras or DVRs from Dahua, Hikvision, Safire, EZVIZ and Uniview, or RTSP streams, viewable in the app.
• Built-in 3.7 V, 3 Ah battery for up to 15 hours on SIM only, or up to 100 hours with Battery Power Saver (not EN 50131 Grade 2 compliant when that is enabled).
• Push, SMS and call notifications set per user, up to 32 automation scenarios, and reporting to monitoring stations over SIA (DC-09), SurGard (Contact ID), ADEMCO 685 and other protocols.
• Tamper alarm, device authentication, frequency hopping, and alerts for jamming and connection loss. EN 50131 Grade 2. Black or white, 163 × 163 × 36 mm, 362 g.

What else you need

• Ajax Jeweller detectors, keypads and sirens for your place; none are included.
• A mains socket (110 to 240 V AC, up to 10 W), a router port with DHCP, and one or two micro-SIM cards with data and the PIN request disabled. Add an SMS or call plan if you want those alerts.
• An Ajax account and the Ajax app on your phone.
• Only if the radio signal is weak at the far end of a large or multi-storey building: ReX 2 range extenders, up to 5 per hub. ReX 2 relays MotionCam photos; the older ReX does not, and neither raises the 100-device limit.
• Only if you want fobs and cards: a KeyPad Plus (hub firmware OS Malevich 2.11 or later), which reads Tag fobs and Pass cards. Tag does not pair with the hub on its own.
• Only if there is no mains at the hub position: the 6V PSU (type A) or 12-24V PSU (type A) boards, which are separate Ajax accessories.
• Only if a security company will monitor the alarm: a monitoring station service.

Installation

Place the hub indoors, at least 1 m from routers, power cables and other Ajax devices, away from metal objects and mirrors, and where the mobile signal is good (0 or 1 bar may fail to dial or send SMS). Slide off the SmartBracket, keeping its perforated part intact for the tamper, and screw it to the wall with the screws from the installation kit rather than tape. Connect the power and Ethernet cables, insert the SIM cards, and hold the power button for 3 seconds until the logo lights; allow up to 2 minutes for the hub to connect and update its firmware. Add the hub to the Ajax app by its QR code or ID, pair your devices, assign rooms and groups, and check that every device shows 2 to 3 bars of Jeweller signal (and Wings for MotionCam). Then set notifications for each user and the monitoring connection if used. An Ajax installer can survey the place and set it up with the Ajax PRO apps.

Software and licences

The hub is managed from the Ajax Security System app, which needs an Ajax account; the Spaces feature needs app version 3.0 or later. Installers use Ajax PRO and PRO Desktop (Spaces need PRO 2.0 or PRO Desktop 4.0 or later). Photo by schedule needs hub firmware OS Malevich 2.19 or later, and photo on demand and by scenario are off by default until you enable them.

Before you buy

• Indoor only: IP20, -10 to 40 °C, humidity up to 75%.
• The radio band depends on the sales region (866.0 to 926.5 MHz options). Confirm the band of the unit supplied matches your other Ajax devices.
• A SIM card is only included in some regions. VoLTE is not supported.
• If you need EN 50131 Grade 2 compliance, leave Battery Power Saver off.
• MotionCam detectors cannot be paired through the older ReX; use ReX 2 for photo relay.
• The 12 V power board made for the original Hub, Hub Plus and ReX is not the one for this hub; Hub 2 (4G) uses the 12-24V PSU (type A).
• Check accessories against Ajax’s device compatibility tool. Choose black or white.
