Audio Sample

Multitone Paging signal, developed by Multitone Electronics in the UK, uses similar coding to POCSAG, but the headers are different and are only compatible with Multitone's range of paging products. The encoding uses POCSAG 1200 as a base. Depending on the setup, you may occasionally hear speech on the same frequency. Multitone paging systems are usually installed in large hospitals and industrial sites. This is used in Multitone Mk. IV, V, VI, and VII pagers.

Some feature a telephone-type handset or a call point for 2-way communication via a PBX, and share the same channel as the pagers. One-way speech is stored in the encoder as a pre-recorded message and is triggered by a closing contact for events such as evacuations, as most pagers support this feature.
