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 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 a hub–detector ping interval of 36 seconds and 30 undeliverable data packets to consider the device lost. With these settings, the hub will detect the loss of the detector in 18 minutes.
To reduce this time, go to the hub settings in the Jeweller section and change the settings. The minimum time for detecting loss of connection with the device is 36 seconds (3 polls of 12 seconds each).
The time before raising the alarm by the communication loss between hub and device is calculated with the following formula:
Note that with the minimum ping interval, short-term interference can lead to loss of connection with the device. Therefore, set the minimum values only if it is critically important to promptly inform about events in the system.
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:
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.
