Helps prevent microwave fires and false alarms.

Safe T Sensor™


Safe T Sensor™ is engineered to help prevent microwave fires and nuisance/false alarms by interrupting power to the microwave at the first sign of smoke.

Helps prevent false alarms that result in:

  • Building evacuations—not practical or safe to evacuate seniors, hospital patients, students, hotel guests, offices (loss of productivity) etc.
  • Fire department responses—costly and put firefighters and private citizens at risk.
  • Tenant apathy—the third time the alarm trips in the middle of the night or otherwise people stop getting out of bed or evacuating.

Proven Technology:

  • Installed in university dorm rooms, hospitals, seniors homes and office buildings throughout North America.
  • Significantly reduces nuisance calls/fire runs and saves money (a lot of money).
  • Presently a simple plug and play aftermarket solution—in time will be an integral component of microwave ovens.

This product is not recommended for use on:

  • Built-in microwave unless the exhaust vents are exposed.
  • Microwaves with a manual dial-timer

How the Safe T Sensor™ Works

The Safe T Sensor™ shuts off the power to your microwave at the first sign of smoke.

Very easy to install and use:

  • The smoke “sensor” is attached magnetically to the microwave.
  • The microwave plugs into the “control box” which is plugged into the outlet.
  • The solution is simple, seamless and requires no change to cooking behavior.

What people are saying about the Safe T Sensor™...

  • The investment in these sensors has reduced fire runs, response hazards, late night residence evacuations, interruption in study time and the cost of fire equipment operation, campus police and personnel required to investigate.

    —Brent Auker, Fire Protection Engineer, Ohio University
  • We installed both Safe T Element® and Safe T Sensor™ in all of our housing units. Prior to this install, we were averaging one fire alarm activation per week. I am pleased to report that since the installation of these fire prevention/lifesaving technologies we have reduced fire alarm activations to ZERO.
