Learn Mode System Sensor Smoke Sensor
The System Sensor™ smoke detector is a Photo-electronic type detector that contains its own Alarm horn and Low Battery Annunciator. It has an output that will trip a special Learn Mode transmitter already built into the detector. A normally functioning smoke detector will have an indicator light that flashes continuously about 4 times a minute. The smoke detector is powered by two 9 volt batteries (alkaline or lithium type);both are monitored. The horn in this smoke detector meets or exceeds current audibility requirements of Underwriters Laboratories (UL);however, the horn may not wake up a sound sleeper if a closed door is between the detector and the sleeper.
