They are probably rate of rise heat detectors, connected to a control panel
and maybe a dialer. If so, they are activated by a sudden rapid temperature
increase or a maximum preset temperature. Why not have an alarm company
check out the system

I just purchased an older home built in 1972. Each room has a little metal
thingie in the ceiling which I was told is a heat sensor.

I don't know if it works, and if it does, how it should work. Is this a
replacement for a smoke alarm?

How do I test it? Do I hold a match near it to heat it up and see what
happens? Does it trigger an alarm?

There are a number of things the home inspection did not cover, the heat
sensor, weight sensitive floor burglar alarms, central vacs etc... that
are
outside of what they consider a "typical and normal inspection".

Just trying to figure out what to do with these heat sensors?

Thanks,

MC
