In pulse mode, Relay can close/open contacts for up to 15 seconds. In other cases, this function is not provided, since each scenario is a single action of the automation device. If one scenario enables the device, another scenario will be required for disabling, or you can disable it manually in the application.
Ajax security system allows you to configure the reaction of Relay, WallSwitch and Socket in response to an alarm or change in security mode, Button click, as well as scheduled actions. The scenario in which the automation device will respond is configured remotely via Ajax apps.
Use scenarios to automate your security system and reduce the number of routine actions. For example, set up water shut-off by alarm of the LeaksProtect leak detector, scheduled heater activation, or automatic clothing the electric lock when the system is being armed.
To create and configure arming/disarming scenario:
- Open the Ajax app, select the hub in the menu at the top of the screen, and go to the Devices tab.
- Select the hub from the list of devices and go to hub settings by clicking on the gear icon .
- Go to the Security Schedule menu.
- Click Create scenario if you are creating a scenario for the first time, or Add scenario if scenarios have already been created in the security system.
Go to the Scenarios menu and click Create scenario if you are creating a scenario for the first time, or Add Scenario if scenarios have already been created in the security system.
Our Relay supports several different relay modes of operation and various states of contact. They can be combined depending on user needs:
- bistable, when the contacts close and open as a switch;
- pulse, when the contacts close or open for 0.5 to 15 seconds, and then automatically execute the action in reverse.
To avoid accidents and equipment failures, we equipped our Relay mechanism with protection against overheating and voltage surges. It is permanently enabled and can’t be disabled. If the temperature where the Relay is installed exceeds 65°C, or 85°C inside the device, the relay opens and sends out an alarm. As soon as the temperature returns to normal, the relay releases and sends out the respective notification.
There are two threshold values for the supply voltage: the lower value is 6.5V, and the upper value is 36.5V. If the power level is too high or too low, protection is activated, the device is disabled and a warning message is sent out. After the supply voltage parameters return to normal, the relay releases and notifies users.
By default, the hub is set to ping detectors every 36 seconds and to signal an alert after 30 undelivered pings. Under these settings, it will take about 18 minutes for the system to recognize a communication failure. You can adjust these settings in the hub settings → Jeweller.
The loop (zone) number is required to add a guarded facility to the CMS along with descriptions of all devices connected to the hub.
The loop (zone) number is available in the settings after activating the group mode in the Ajax application:
- Hub Settings Groups
Having selected a group, you will see a list of its devices. Each device has a Device No. (or DeviceIndex in Ajax PRO Desktop) that corresponds to the loop (zone) number. A number is assigned when a device is attached to the Hub. The first added device has the first loop (zone) number.
After a device or a detector is removed, its number will be assigned to the next added device. However, the numbering of other devices will not change.
In the Ajax app, select the «Devices» tab . Information about the firmware version and device ID is located at the very bottom of the tab with the device parameters.
Go to the Device tab , select the device you want to check.
