Reset of four wire smokes is accomplished by removing power to the smokes
for a few seconds, you can have the four wire smokes on different zones so
you can identify which building caused the alarm and still use a common
reset, but Jewellfish brings up a possibly overlooked issue if you are
located in the US. The 1864 isn't rated for commercial fire in the US.
