5.3 Bell Silence/Bell Trouble
A bell silence switch on the 866 module is provided to prevent indicating devices from sounding during
system testing. When the Silence position is selected, a 15-second delay occurs before the 866 bell trouble
contacts (terminals 7 and 8) open. Select the Normal position after testing to return the 866 module to
normal operation.
