About the Ajax System

No Wires, No Fuss and Simple to Program!!

Ajax is a multi-award-winning high-end wireless smart alarm system that is completely setup and controlled from Android and iOS devices. An Ajax Hub (control panel) is required to control the system and ready to work out the box. Battery backup, Power Supply, GSM and IP modules are conveniently built-in. 

Depending on the Hub, a combination of up to 200 wired (using Ajax MultiTransmitter) and wireless devices can be added to the system creating a multitude of solutions for indoors and outdoors as well as early detection of fire and flood. The system can be controlled by 200 users and admin controls user permission. Create up to 25 groups (partitions) that can be independently armed with a single tap of your finger.

Automate your appliances, control and protect gates, turn on lights, receive electric fence alarm alerts on your phone and control your energiser from anywhere.

Scenarios can automatically arm and disarm your alarm or allocated groups at specified times. Or they can be setup to control lights, appliances other devices by alarm when arming / disarming, even start the coffee machine when the alarm disarms in the morning. 

Add your safe, man cave, garden shed, workshop or trapdoor to a 24-hour group that remains unaffected by normal arming and disarming and hide the group/s from other users.

Panic button on the app that sends a Geolocation to your inner circle letting them know of your whereabouts when you need help.

System Settings

There are a few settings that need to be adjusted to ensure that your Ajax system operates optimally. We offer free remote support for all our DIY customers (Stemar / Ajax Alarm Shop) – Setup and configuration, creating groups and other system and user functionalities.

Hub Activation

Adding a Device

Integration of Existing Wired Alarm Systems

Got an existing wired alarm and don’t want to replace all your wired devices?

No Problem!!

Ajax MultiTransmitter is an 18-zone smart panel designed to replace existing wired alarm control panels. Simply connect the wired devices to the MultiTransmitter, pair it with an Ajax Hub and your wired devices seamlessly integrate into the Hub transforming them into smart and secure devices. Each device is configurable via the app and fully controlled from your phone, no keypads required.

Not only for Homes and Businesses

Ajax opens up new possibilities for protecting people and their possessions in areas where no 220v power is available. 

Ajax 12v PSU for Low Voltage Applications

Interchangeable onboard Power Supply Units are available allowing Ajax to be powered up by either low or high voltage power sources (12v or 220v). This means that Ajax is not limited to 220v establishments but can also be installed in Campervans, Caravans, Yachts as well as building sites, warehouses, storage facilities etc.

Insert a SIM card into the Hub, connect it to a 12v power source and you’re good to go.

The Justworx SIM card automatically connects to the strongest network in 105 countries so whether sail from here to China or travel the globe in your campervan, where there’s signal, you’ll be connected. Here’s the Justworx Global Coverage map.
