RADION smoke

The RFSM is a non-latching wireless smoke detector that sends an alarm signal to the receiver.

The following features include:

– A visual status LED

– A built-in sounder for alarm alerts

– Under normal conditions, the red LED flashes once every 8 sec while the sensor monitors

the surrounding environment. When the sensor detects smoke, the LED changes from

flashing to steady ON and the sounder produces a loud, continuous tone. Refer to the

LED table for more information.
