Answers
Common questions
Which door phones does it fit?
LTE-ready Akuvox models: R20K-L, R29C-L, E18C and X916S-L. Check that your door phone is an LTE-ready (-L) version before ordering.
Will it work on Australian networks?
In the R20K-L it covers LTE bands 1, 3, 5, 7 and 28 among others, which include the main Australian 4G bands. Check coverage at the door first.
Is a SIM included?
No. Use a data SIM from your chosen carrier; it goes in the door phone’s SIM slot, not on the module.
Is it hard to install?
The rear cover comes off, the module is seated in its socket and fixed with one screw, the RF cable(s) are clipped on and the cover goes back. Akuvox’s guide is attached.
Can I open the door phone with the SIM fitted?
No. Akuvox warns against opening the rear cover while a SIM card is installed — remove the SIM first.
Do I still need power at the door?
Yes. LTE replaces the data cable, not the power supply.
Is it the same module as the S535 LTE module?
No. The S535 uses its own plug-on LTE expansion unit (AK-S535-LTE) that mounts below the screen.
LTE door entry.
The LTE module adds a 4G connection to an LTE-ready Akuvox door phone where there is no network cable.
Installation & safety notice
Power the door phone down before fitting. Do not open the rear cover with a SIM installed. The module draws its power from the door phone.
