I recently installed the SITERWELL Hardwired Interconnected Smoke Detector (Photoelectric) and I'm very satisfied with its performance so far. The installation was straightforward, and the fact that it can be interconnected with other units gives me extra peace of mind knowing that if one alarm goes off, they all alert the household.
The photoelectric sensor is a big plus because it detects smoldering fires quickly, which adds another layer of safety. The included 9V backup battery ensures the alarm keeps working even during a power outage—a key feature for any hardwired system.
The alarm is loud enough to be heard throughout the house, and the build quality feels durable and reliable. Overall, this smoke detector is a great value for the price, and I highly recommend it for anyone looking to upgrade their home safety system.
