PA2S SIP paging and intercom gateway with call key, audio and network connectors

The bridge between a legacy speaker line and the network

This is the gateway role in the range: a SIP call or a broadcast arrives on the network, and the audio leaves through the gateway line output for the speaker line it serves. The analog horn speakers in the source material are driven by the PA3 and PA2S gateways.

SIP-based paging: live paging and MP3 broadcast
Line out for an external active speaker
Drives the range legacy analog horn speakers
Megabit Ethernet, with camera NVR recording over a standard RJ45 interface
Registers as a SIP endpoint on the site network

The public-address deck frames this as the bridge that lets existing analog broadcast cabling be reused rather than replaced.

Call keys, contacts and recording

SOS call key interface for a one-click call
One speed-dial key interface
One short-circuit input and one short-circuit output for external linkage
One built-in relay
3.5 mm recording output
Camera support through an external accessory, up to a 1080p external camera

An optional gateway kit for the PA3 and PA2S adds a 5 W / 8 Ω speaker module, a 720p camera module, a high-sensitivity pickup microphone module and a waterproof stainless-steel button with an LED indicator.

Power, network and provisioning

PoE (IEEE 802.3af) or 12 V–24 V 2 A DC
Megabit Ethernet
Auto provisioning over DHCP, TR069 and SIP PnP
Working temperature −30 °C to 60 °C

Protection rating, impedance, dimensions and weight are not stated for this model, so we do not publish them.

Where it fits on site

Retrofit of an existing speaker line

The gateway puts a legacy speaker run onto the SIP system instead of replacing the cabling and the speakers.

Intercom point with a call key

The SOS call key interface gives the position a one-click call, with a speed-dial key beside it.

Site with a camera at the gateway

An external camera up to 1080p can be attached through the accessory, with NVR recording over the standard RJ45 interface.

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

A212 wall speaker

The wall speaker that covers the zone the gateway feeds.

A201 ceiling speaker

Ceiling coverage for indoor zones on the same system.

Frequently asked questions

What kind of gateway is the PA2S?

A SIP intercom and paging gateway. It registers like a SIP endpoint, plays live paging and MP3 broadcast, and puts the audio out through its line output to the speaker it serves. Auto provisioning runs over DHCP, TR069 and SIP PnP.

How is it powered?

Two ways are stated: PoE (IEEE 802.3af) and 12 V–24 V 2 A DC. Tell us what is available at the position and we will confirm the arrangement on the quotation.

Can it use the speakers we already have?

The gateway has a line out for an external active speaker, and the range legacy analog horn speakers are driven by the PA3 and PA2S gateways. Send us the existing speaker list and amplifier arrangement and we will confirm what can be reused.

Can a camera and a call button be added?

Yes. The SOS call key interface takes a one-click call button, and camera support through an external accessory reaches up to 1080p, with NVR recording over the standard RJ45 interface. An optional gateway kit adds a speaker module, a 720p camera module, a pickup microphone and a waterproof button.
