A212 SIP wall-mounted speaker shown in black and white finishes

Coverage where the sound has to be aimed

A wall position suits a corridor or a specific zone better than a ceiling unit, which is why this model carries an optional angle-adjustment bracket and a volume knob on the outside of the housing.

2-way coaxial speaker: LF woofer and HF tweeter
Up to 20 multicast zones with prioritisation
HD intercom and lossless broadcast; offline timed broadcast
G.722 and Opus, sampling rate up to 44.1 kHz
Can drive an additional analog passive speaker
External knob for volume adjustment

Power over the cable, with a printed split

The speaker takes 10/100 Mbps Ethernet with integrated PoE. The two sources describe the power differently, which matters when the zone has to hit full output.

Maximum 8 Ω 15 W output; up to 15 W (DC) from the built-in class D amplifier
Healthcare material: PoE 8 W, PoE+ 15 W
Chinese deck: PoE IEEE 802.3at
DC power is also stated

Confirm which PoE class the position can supply on the quotation — at PoE 8 W the output is lower than at PoE+ 15 W.

Alarm linkage and management

Customisable alarm action for emergency warning
Linkage with security alarming devices
Four stated modes: serverless, UC convergence, broadcast system and external linkage
SIP, HTTP API, short-circuit I/O and video linkage
Managed over the web and by device-management software

IP rating, dimensions and weight are not stated for this model, so we do not publish them.

Where it fits on site

Corridor aimed along its length

The wall position with the optional angle bracket puts the sound where people walk, in up to 20 multicast zones.

Zone that needs talkback

The omnidirectional microphone supports talkback and listening from the same unit.

Zone with alarm linkage

The customisable alarm action and the documented linkage with security alarming devices let the zone react to an alarm event.

iSpecifications are taken from the public-address solution deck, the Chinese security and broadcast brochure and the healthcare material. The PoE wording differs between sources (PoE 8 W / PoE+ 15 W against IEEE 802.3at), and IP rating, dimensions and weight are not stated; confirm the power arrangement on the quotation.

Compatibility boundaries

This model uses standard SIP and the interfaces listed in the specification table. Confirm the PBX, SIP provider or platform against those interface notes before the order; where the documentation does not state a value, the table records it as not stated rather than estimating. PoE, analog port variants, power options and card compatibility are fixed at order time.

Handover, spares and support

Extension plan, provisioning and interface language can be prepared before dispatch. Remote support continues after handover. Spare-part, warranty and service terms are confirmed in the quotation for the models and quantity ordered, so they are not printed as a single figure here.

Where it sits in the system

A201 ceiling speaker

The ceiling option for even indoor coverage.

A513W video speaker

Frequently asked questions

Which PoE class does the A212 need?

The sources describe it two ways: PoE 8 W and PoE+ 15 W in the healthcare material, and IEEE 802.3at in the Chinese deck. The output differs with the supply, so tell us what the switch can deliver and we will confirm the configuration on the quotation.

How loud is it?

The stated maximum is 8 Ω 15 W, with up to 15 W (DC) from the built-in class D amplifier. There is no dB figure in the source material, so we do not publish one.

Can it drive a second speaker?

Yes. The A212 can drive an analog passive speaker, which is useful where a zone needs a second position without a second network drop.

Does it work with alarm devices?

Yes. A customisable alarm action and linkage with security alarming devices are stated, and the speaker is managed over SIP with an HTTP API and short-circuit I/O. Tell us the alarm devices on site and we will confirm the wiring on the quotation.
