Its a wireless receiver unit which calls the fire department in case
of a fire.

You probably need to figure out how it converts 120v to whatever it
needs. It may be that you could rip out its power supply and
substitute one for your line voltage.

For a purely resistive load, I think a series diode might work - but
for something with regulation or it's own regulator followed by a
filter cap, probably not.
