How to Plan a School PA System in Kenya: Assemblies, Classrooms and Emergency Announcements

Short answer: a good school PA system is planned by zone. Decide which areas need announcements (classrooms, corridors, dormitories, field, hall), which need full sound for speech and music (assembly hall, field events), and how announcements will work during a power cut or emergency. Then size speakers, amplifiers and microphones for each zone.
1. Map the zones
- Paging zones: classrooms, corridors, offices, dormitories and dining hall, usually with ceiling or wall speakers on a 100V line system.
- Assembly and events: hall or field, needing higher-output speakers, wireless microphones and a mixer.
- Outdoor areas: weather-resistant horn or column speakers for the field and gates.
2. Decide how announcements are made
Most schools need a desk paging microphone at the office with zone selection, so staff can address one block or the whole school. Scheduled bells and pre-recorded messages can run from the same system.
3. Plan for emergencies and power cuts
Announcements matter most during an emergency. Put the PA amplifier and paging microphone on a UPS or backup supply, and agree with the school which messages and zones are used in an evacuation.
4. Choose durable, serviceable equipment
School systems are used daily for years. Choose equipment with local support and spare parts, secure microphones and amplifiers in a lockable rack, and label zones clearly so staff can use the system without training each term.
5. Budget for maintenance
Check speakers, cables, microphones and batteries each term, and test every zone before exams, sports days and prize-giving.

Frequently asked questions
What is a 100V line PA system?
A 100V line system lets one amplifier power many speakers over long cable runs, which suits schools and hospitals with several blocks. Each speaker has a transformer so volumes can be set per area.
Can the PA system also ring school bells?
Yes. Many systems include a scheduler that plays bells or recorded messages at set times in chosen zones.
Will the PA work during a power cut?
Only if it is connected to backup power. We recommend putting the amplifier and paging microphone on a UPS or generator-backed supply.
