HOOTER No. 2C
Originally the Buzzer No. 22, this was a 250v AC Mains operated hooter, normally controlled via a mercury switch unit.

The Hooter No. 2C must be isolated from mains power supply before approaching the Hooter or removing cover of associated relay switch Unit.

This Hooter is very loud!

BT replaced the Hooter 2C with Mayhem tonecallers.
