Unboxing and demonstration of a vintage K-F Industries smoke/gas/heat detector

This 'Save-A-Life' alarm was made by K-F Industries, Inc. of Philadelphia, PA in around 1970. The alarm is marketed as a smoke, gas, and fire detector however there is only a gas sensor and heat sensor on the PCB. I am unsure if the gas sensor also doubles as a smoke sensor, but as you can see I was unable to get it to sound with smoke. Also contains a Delta-Larm mechanical squealer horn and sounds in a very unique 120-HZ buzz tone. This is one of two K-F Industries models that have surfaced, the other being a large round smoke-only model. Very neat little unit!
