AJAX Hub 2 Plus Manuel D'utilisation page 42

A request for connection to the hub is transmitted for a short time at the
moment of switching on the device.
If KeyPad failed to connect to the hub, switch it off for 5 seconds and retry.
The connected device will appear in the app device list. Update of the device
statuses in the list depends on the detector ping interval in the hub settings (the
default value is 36 seconds).
There are no pre-set passwords for KeyPad. Before using a KeyPad, set all necessary
passwords: common, personal, and duress code if you are forced to disarm the system.
Selecting the Location
The location of the device depends on its remoteness from the hub, and
obstacles hindering the radio signal transmission: walls, oors, large objects
inside the room.
The device developed only for indoor use.
Do not install KeyPad:
1. Near the radio transmission equipment, including that operates in 2G/3G/4G
mobile networks, Wi-Fi routers, transceivers, radio stations, as well as an
Ajax hub (it uses a GSM network).
2. Close to electrical wiring.
3. Close to metal objects and mirrors that can cause radio signal attenuation
or shading.
4. Outside the premises (outdoors).
5. Inside premises with the temperature and humidity beyond the range of
permissible limits.
6. Closer than 1 m to the hub.
