Option 1: Hush mode is not canceled for any reason. If the test button is

pushed during Hush, the unit reverts to normal sensitivity to test the

unit, but when it comes out of test, it resumes in Hush where it left off.

Option 2: The Hush mode is canceled if the reduced sensitivity

threshold is exceeded (high smoke level) and if an external

interconnect alarm is signaled. If the test button is pushed during Hush

after the test is executed, Hush mode is terminated.
