Interfacing Telephones to PA / Tannoy Systems

Telephone enable your Public Address / Tannoy System!

Most PA / Tannoy systems we see today employ dedicated microphones for making their voice announcements. Microphones have been used in this way for many, many years, providing a quality and reliable means of system input.

With the ubiquitous use of telephone handsets we now see so freely available, it is possible to interface these to most existing or new PA / Tannoy systems with the introduction of a telephone interface unit. Primarily, the telephone interface unit does exactly what it says, it provides an interface for someone using a telephone handset to make announcement / paging calls to the PA / Tannoy system. There are a number of benefits and capabilities provided by telephone interface units when used in this way and compared to traditional microphones.

Telephone Interface Units and location independence

By adding a telephone interface to a PA / Tannoy system, we have introduced the capability to make announcements and paging calls from telephones handsets. The telephone handsets are not special or dedicated in the way that microphones are. They are regular telephone handsets, that might be local to the building, the site, or in fact they can be anywhere, national or even international. With this location independence, we find customers realising benefit in ways such as:

- Use of the PA / Tannoy system with first aid / response policy
- Day, night, shift pattern changes (eg. no expensive deployment or part employment of dedicated microphones in different places).
- Make announcements / paging calls from places that are impractical or impossible to do so by using microphones (eg. between buildings or sites, roads, towns..... places microphones cannot reach).
- No expensive microphone equipment installation or cabling, simple adds, moves and changes.

Telephone Interface Units and recorded announcements / paging calls

Some telephone interfaces offer the capability option of pre-recording announcements / paging calls before they are released to the PA / Tannoy system for broadcast. This popular option allows the person making the announcement to re-record the message, and only release for broadcast when they are happy.
