Wie man zwischen Generationen des GSM Fixi unterscheidet
Here is a description of how you can tell these two products apart.
A) If you have a value code for the product, you have a GSMFixiPlus. If so, you can control the product with Sikom Connect.
B) Press the F button. If the light comes on immediately you have a GSMFixiSMS (remember to turn off F again). If you have to press and hold the F button for about 5 seconds before the light comes on you have a GSMFixiPlus
C) Take a look at the silver label at the bottom of the product. Old GSMFixiSMS has model number 300-8090V16 to 300-8090V19 while new GSMFixiPlus has model number 300-8090V20.
D) Turn off the power to the product. GSMFixiPlus has Eingebauter Akku and will remain on for a few hours after a power failure (the control LEDs will still be on). On GSMFixiSMS the control LEDs will go off as soon as the power is disconnected (also remember to disconnect -BP12- battery backup if present).
E) Open the cover. If there is a battery directly under the cover you have a GSMFixiPlus.
