Paging System Design Selecting a Paging Control Unit

Page Control Selection Selecting a paging control unit for your application depends on several considerations: • Telephone Access method • One-Way paging, Talkback (two-way) paging or combination of both • Total number of zones (stations) • Special Features such as Emergency Page Override, Background Music, Programmable Features Per Zone, Night Ring, Time Clock Tone and Alert Tones
