For schools
Broadcast & Lesson Time Systems
Lesson time signals, announcements and evacuation messages for schools – so you can focus on teaching

For schools
Lesson time signals, announcements and emergency messages in one system
From signal horn to network system
HAGO supplies broadcast and lesson time systems for schools of every size. From electric signal horns driven by a clock contact, to loudspeakers that play a tone via a clock and amplifier, to a programmable system with group announcements, optionally connected to the school network.
Developed with schools
Our SHP systems run on components and software we design ourselves, based on 40 years of experience and close contact with many schools. That is how specific questions from schools became user-friendly functions: for lesson times, announcements and safety and evacuation.
Always on time through DCF or internet time synchronisation
Several timetables, switched with one action
Announcements in the whole school or per group
Emergency and evacuation messages (SHP/8 Plus)

Always the right time
SHP/SH and SHP/TM run exactly on time thanks to the DCF antenna. SHP/8 Plus synchronises its internal clock via the internet or a DCF receiver. A holiday calendar prevents signals during school holidays, so the neighbourhood is not disturbed.
