Ideal for quick responses to fast flaming fires, this USI electric smoke detector best protects your family against sudden threats and dangers. Whether it’s a new installation or a replacement, this model detector is perfect for houses, apartments, and mobile homes.

Equipped with a convenient silencer option, non-hazardous alarms, and low-danger situations can be temporarily quieted. Its smart interconnect feature allows for the linkage of 18 additional interconnected smoke alarms. In the event of power outages, this wired smoke alarm comes stocked with a 9-volt battery that will take over once any kind of power interference is detected. This will ensure a continuous flow of power at all times.

When smoke particles are detected inside the chamber, the alarm will flash its red LED light, and when it’s running idly, the green LED light will indicate the alarm is functioning properly. The model is fully protected by dust and contaminant covers, meaning removal of the alarm is unnecessary during any construction or renovation procedures.

As one of the leading wired smoke detectors, this model is UL listed, and approved by both the California State Fire Marshal and the Federal Housing Authority. For maximum protection, install the USI electric smoke detector 1204 inside every bedroom, outside every sleeping area, and on all levels of the home.
