February 6, 2018We purchased our home about five years ago, it was built in 2007. We have some very high ceilings and the house came with eight ASI Electric Hardwired Photoelectric Smoke & Fire Alarms w/Battery Backup. We were replacing batteries but were still having problems with beeping and the alarm going off.. We decided to replace some units and were unsure of replacement units that we could find locally. We went online to Universal Security Instruments Store and found exactly what we needed at about half the price found locally. We easily ordered online, received free shipping and delivery within a week.

Bought this smoke alarm to replace an older model. It took less than 5 minutes to change out. Happy with unit and ease of installation.
