Hello,
This topic is dedicated to the William Howard School Speaker System in Cumbria. It is used during fire drills to organise the staff and students. There are at least 6 speakers in the system on the artificial grass turf, where the fire assembly point is located. When I acquire any I will upload higher quality images here. The speakers themselves seem to be of at least 2 different models and manufacturers, and seem to be relatively old, as inferred from the amount of physical abuse they have received from years of hard rain, stray footballs, etc.
If you know anything about this system, don’t hesitate to add it to this topic!
Thanks
