Macrosphere bell systems are designed to operate on the schools existing network infrastructure. By doing this, costs normally associated with a school wide installation are reduced, as no trenches or pit access is required.

No part of the system requires access outside of the schools network, so security is not compromised.


The analogue system is single zone (all school announcements). Bells tones and music can be played as the speaker system for both designs are of music quality. Outdoors speakers are IP 65 Rated for weatherproofing.

The recommendation for every classroom to have an internal speaker installed, so the teachers and students can hear bells, fire and lockdown warnings within the classroom. (Most classrooms are air conditioned).

The digital system, is a computer based, information and tones transfer but using a data port within the network (please note this system is separate from the DoE System). The digital system does not require cabling between the building, not like the analogue system that requires all cabling between the buildings to operate the system.

We will design both systems and compare the quotes. Sometimes, the design is more economical to have digital system over an analogue system. Both systems have manual override bells if required.

Macrosphere can also install duress systems and snake alerts, if required.
