The AK-E20S is Akuvox’s E20S push-button emergency station. Press once and it calls a guard room, reception or a SIP phone hands-free — no handset, no screen, nothing to break.
This SKU is the intercom station only.
You receive the E20S station. The in-wall box, PoE switch and the answering endpoint (indoor monitor, SIP phone or PBX) are sold separately.

Press. Talk. Help arrives.
Lifts, car-park lobbies, disabled toilets, corridors and receptions: wherever someone may need to call for help, E20S gives them one obvious button and a clear voice line.

Call
One button. Hands-free.
A single call button on the stainless front dials a pre-set SIP number. Built-in speaker and microphone with echo cancellation keep the conversation hands-free.
One SIP account, G.711a / μ and G.722 codecs, QoS and auto-answer — so a guard can also call the station back and talk straight away.
Tough
316 stainless, IK10.
The 316-grade stainless steel front is rated IK10, the top impact level, for public corridors and lifts where equipment gets knocked.
At 100 × 100 × 37.7 mm the panel sits flush over a standard single wall box. The E20S is rated for indoor use.

Install
A standard wall box and one cable.
E20S fits 86-type and 1299 single in-wall boxes. One Cat5e/Cat6 run with 802.3af PoE carries power and network.
Set DHCP or a static IP, register the SIP account, and the station is ready. NTP keeps its clock right.

Answers
Common questions
Can it be used outdoors?
No. The E20S datasheet states indoor use only. For outdoor help points use the E21A (audio) or E21V (with camera), which are IP65.
How is it powered?
PoE 802.3af only — there is no DC input.
What wall box does it fit?
86-type and 1299 single in-wall boxes, or the E20 in-wall kit.
Does it have a camera or door relay?
No. E20S is an audio-only push-button station. For video, look at the E21V.
What can it call?
Any SIP endpoint: Akuvox indoor monitors, SIP desk phones or a SIP PBX.
A compact help point, local stock.
Choose E20S for indoor help points on a standard wall box. For outdoor or camera-equipped help points, look at the E21A and E21V. Order through Infront Technologies for Australian stock and SIP setup advice.
