449AT - GE Photoelectric Smoke Detector 4-Wire w/ Heat 6/12VDC

The 449AT GE Photoelectric Smoke Detector is perhaps the most intelligent smoke detector on the market today. Smoke detectors are certainly crucial to any home security system, but those of us who aren't security experts might not know if we're even installing the unit in the right place! Luckily, the folks at GE thought about just that when they equipped the this Photoelectric Smoke Detector with a Self-Diagnostics capabilities, which includes automatic sensitivity testing. What this means is that the smoke detector continually monitors its own sensitivity and operational status, and provides a visual trouble indication if it drifts out of sensitivity range or fails internal diagnostics. That way you'll never run the risk of having your smoke detector installed improperly! Furthermore, the GE Photoelectric Smoke Detector has superior protection against fals alarms caused by dust, insects, RF and ambient light.
