resonance pressed alloy-steel gong to ensure a
loud clear-tone ring. The operating mechanism is
fully enclosed and the gong is red stove
enamelled for long life. The bells are designed
for internal use, but gasket sealed conduit boxes
can be provided for external use.

The loop powered addressable sounder unit is a
low frequency Banshee that can be both
controlled and powered via the MINERVA
analogue addressable fire controller. With this
facility, no separate sounder circuit needs to be
installed, providing significant cable installation
savings. The sounder output is set at a
continuous fast sweep (9 time/sec) but may be
pulsed (alert signal) under the control of the
MINERVA fire controller.
