Description
The Ajax Relay is a wireless 12V low-current dry contact relay designed to control low voltage devices and appliances remotely such as Gates, Garage motors, Electric locks etc.When used in conjunction with the Ajax system, the Ajax Relay allows you to make use of automation scenarios so your security system not only reports threats but also actively counters them.
The dry contact is not galvanically connected to the device power supply so that it can be used both in low-voltage and household networks. The relay can easily be connected to a power supply unit paired with a backup battery.The Relay can be controlled manually via the Ajax app, Button press or by Scenario.Product Code: 11035.19.NC1Please note: Ajax Hub required for operation.Compatible with all Ajax Hubs and Range Extenders.

Operating principle
The Ajax relay is a dry contact relay to control a power supply remotely. The relay is installed in the electrical circuit gap to control the power supply of devices connected to this circuit. Relay is controlled via the device function button (by pressing and holding it for 2 seconds), the Ajax app, Button, and automation scenarios.Relay is powered by a 724 V power supply. Recommended power supply voltages: 12 V and 24 V.The Ajax relay features potential-free (dry) contacts. Dry contacts are electrically isolated to the relays power supply. Thus, this device can be used in low-voltage and household networks, for example, to simulate a button, a toggle switch, or to control water shut-off valves, electromagnetic locks, irrigation systems, gates, barriers, and other systems.Relay commutes one single pole of the electrical circuit. The Ajax relay can operate in bistable or pulse mode. In pulse mode, you can set its duration: from 0.5 to 255 seconds. The operating mode is selected by users or PRO with admin rights in the Ajax apps.A user or a PRO with admin rights can select the normal state of the relay contacts:Normally closed the relay stops supplying power when activated and resumes when deactivated.Normally open the relay supplies power when activated and stops when deactivated.
Automation scenarios
Ajaxs scenarios offer a new level of security. With them, the security system not only notifies about threats, but also actively resists them.Scenario types with Ajax Relay and examples of usage:By alarm. Lighting is switched on when an opening detector activates the alarm.By security mode change. The electric lock is automatically blocked when the object is armed.By schedule. The irrigation system in the yard is switched on according to the schedule at the specified time. Lighting and TV are switched on when the owners are away, so the house doesnt seem empty.By pressing Button. Switching on night lighting by pressing the smart button.By temperature. The heating is turned on when the temperature in the room is lower than 20C.By humidity. The humidifier is switched on when the humidity level drops below 40%.By CO concentration. Supply ventilation is turned on when the carbon dioxide concentration level exceeds 1000 ppm.
Control via the app
In Ajax apps, you can switch on and off electrical appliances connected to an electrical circuit controlled by Relay.Click the toggle in the Relay field in the Devices menu: the state of the relay contacts will change to the opposite, and the connected electrical device will switch off or on. This way, a security system user can remotely control the power supply, for example, for lighting or an electric lock.SPECIFICATIONS OF THE AJAX RELAY:
