Snom PA1


The Snom PA1 is a new audio device, which can be used as an extension of any public address system, allowing you to connect a loud speaker or PA amplifier up as an extension to a VoIP system. Ideal for broadcasting announcements or playing music, either through connecting to external speakers or a headphone connection. The Snom PA1 can be installed to walls and ceilings and uses the familiar Snom hardware and firmware - so you know it is of the highest quality. It can be powered by PoE or a 5v power supply.

The announcement is generated by making a call from a Snom telephone. The PA1 also has its own private number in the same way that all devices connected to a SIP system do.

Snom PA1 Main Uses

  • Public Address System: Connect a 4W speaker or an amplifier system to the PA1 audio output. Register the PA1 as an extension on your SIP system in the same way you would any other Snom phone. When you call the PA1 it auto-answers the call and passes either one way or two way audio (if a microphone is also connected).
  • Door Entry System: Using a special firmware version, the PA1 can be configured as a SIP door entry system. Connect a 'door bell' push button, external microphone, external speaker then register the PA1 as an extension to your SIP system in the same way as any other Snom phone. The PA1 will then place a call to your SIP system so that you can speak to whoever is at the door (even if you aren't in the building). The PA1 also has four DTMF controlled switched outputs which can be connected to an electronic door lock, outside light or perhaps to activate an IP camera recording.

The PA1 is not limited to these two uses, it can be used to "SIP enable" any device which has normal audio inputs and outputs. With suitable relays connected to switched outputs it could also form the basis of a home automation system controlled via your SIP phone system.
