Easy to install, LOUD alarm, and nice Hush feature
on July 21, 2010
I didn't know about replacing smoke alarms every decade until very recently. The units in my home were two decades old, hardwired AC with no battery backup. They tested fine but after twenty years it is certainly time to replace them by any standard. There are three in my home, one on each floor.
After doing a bit of research and being a smart consumer, I decided the PI2010 was the best choice out there. I purchased them up at a local big box home center because the price was highly competitive with Amazon and I didn't have to wait for shipping (even free super saver shipping).
In the box was a mounting bracket, three-wire harness, instructions, screws, and the smoke alarm.
Installation was a breeze - shut off the power at the circuit breaker first, removed the old alarms and harnesses next. The instructions with the PI2010 made it clear to not pull out the battery shipping tab until the units all had AC power applied. The mounting bracket was able to use the existing screws so I didn't have to even remove them from the ceiling box. The harness wired up easily and after plugging it into the alarm it only took a small twist to secure it to the mounting mounting bracket. After turning the power back on, I pulled the battery tabs out of each alarm. I tested each one, and had a friend make sure the units on the other floors sounded also.
The alarms in this model are about twice as loud as my old smoke alarms, almost ear splitting loud so I believe there's no chance to sleep through it. A green LED tells you it has AC power and there is a red LED that flashes every so often to say it's working. I may find the 'hush' feature useful for my occasional kitchen disaster, but fanning a cookie sheet is my usual move when I burn something too crispy.
The fact that the battery compartment is on the backside does not detract from the alarm. just a simple quarter twist and the unit comes off the bracket. On that note, it does have an anti-tamper feature that if you choose to activate, removing it from the bracket requires a read through the instructions and a lot more effort.
All in all, it was a breeze to install, it looks and feels professional, it is the loudest alarm I've ever heard, and the hush feature is great.
I plan on extending the wiring and installing these in each of the bedrooms, above and beyond minimum code.
