Abstract

The accessory is for use with deep freezers, cold rooms etc., having one or more audible indicators connected to the temperature signal lamp controlled by the thermostat. An interrupter or other switch is connected in series with the indicator, switching the sound off momentarily until the thermostat returns to normal operation. The indicator and interrupter can be mounted in a different room to that containing the deep freezer, or alternatively both, or only the interrupter, can be mounted on the freezer itself.
