Akuvox · R20B · 3-button door station
One button per tenant.
Three labelled calls, one compact plate.
The AK-R20B3BONWALL is Akuvox’s R20BX3: the compact R20 door station with three speed-dial buttons and name plates, in silver aluminium. Visitors press the right name, the right resident answers — simple for guests, tidy for the building.
This SKU is the surface-mount door station only.
You receive the silver R20B 3-button surface-mount door phone. Indoor monitors, rain hood, PoE switch and lock hardware are sold separately.

- PoE 802.3af switch or injector

Press a name. Talk. Open.
Each button dials its own flat or office over SIP, so residents answer on an Akuvox indoor monitor, the SmartPlus app or any SIP phone. Residents let themselves in with a card or an Android phone.
Call buttons
Three names, three direct lines.
Each of the 3 buttons has its own name plate and is set to a SIP number, Akuvox indoor monitor or SmartPlus account in the web portal.
No directory to scroll and no codes to remember — ideal where visitors are couriers and guests.
Compact
Fits where bigger panels can’t.
185 × 84.5 × 24 mm aluminium, IP65 against rain and dust, −30 °C to +60 °C, with a tamper alarm.
2 MP 1/2.8″ camera, 110° (H) / 58° (V), 1080p at 30 fps, with automatic IR night lighting and a 0.1 lux minimum. ONVIF and RTSP for NVR recording.
Access
Card, NFC or app for residents.
The 13.56 MHz and 125 kHz reader takes EM, MIFARE and DESFire EV1 / EV2 / EV3 cards, plus NFC from Android phones. Up to 25,000 cards and 5,000 users.
Two relays drive two doors or a door and a gate. Two inputs, Wiegand in/out and RS485 connect exit buttons, door sensors and controllers.
How it works
From name plate to open door.
01
Mount
Surface-mount the station at the entry; add a rain hood if exposed.
02
PoE and SIP
Run 802.3af PoE to the RJ45 and register the station with your monitors, SmartPlus or SIP PBX.
03
Assign buttons
Map each of the 3 buttons to a resident, then slide printed names into the plates.
04
Test the door
Call each button, check the picture day and night, and confirm the relays release the right locks.

Answers
Common questions
How does this differ from the other R20B models?
Only the number of call buttons. The 2-, 4- and 5-button R20B models share the same camera, reader, relays and 185 × 84.5 × 24 mm housing.
Does the R20B have a keypad for PIN entry?
No. Residents use cards, NFC or the SmartPlus app. For PIN entry choose the R20K keypad model.
Can each button ring a different apartment?
Yes. Each button is programmed to its own SIP number, Akuvox indoor monitor or SmartPlus account.
Which cards does the reader take?
125 kHz EM and 13.56 MHz MIFARE and DESFire EV1 / EV2 / EV3 cards, up to 25,000 of them, plus NFC from Android phones.
What power does it need?
IEEE 802.3af PoE from a switch or injector.
Can it be flush-mounted?
Yes. This SKU ships for surface mounting; the R20K / R25K / R20B in-wall kit recesses it, and matching rain hoods cover both install types.
Is an indoor monitor included?
No. Add one compatible Akuvox indoor monitor, SmartPlus account or SIP endpoint per tenancy.
The right button count.
Pick the R20B that matches the tenancies: this 3-button model, or the 2-, 4- and 5-button versions in the same housing. Need more flats? Step up to the R20K keypad.
