Tools and Hardware Reviews of BRK Brands 9120B Hardwired Smoke Alarm with Battery Backup, Single Individual from Contractor Pack
Customer Review: 3 days and counting of random beeping...
Summary: 1 Stars
I am about to tear these things out of the ceiling. It's 5am, and it's the 3rd night of beeping by these...
When I bought our condo 3 years ago, the developer hard-wired these into all the units--so we all have the same problems. Each condo unit has 2 alarms networked together. First, EVERY OTHER time I use the oven, the fire alarm goes off. In 3 years, we are at 100% false positives with over 100 "fire alarms" in my unit alone. We have a routine to deal with it--we stand under one waving a dishrag until the alarm stops. These false alarms are so bad that everyone in the building ignores them because they go off whenever someone cooks. We have to forewarn guests that the alarm will go off if we're cooking--it's pathetic. In addition, they are made of very flimsy, cheap plastic. Pull the cover off a few times and you'll be throwing away bits and pieces of white plastic or the battery pack won't stay in.
But the big problem started a few days ago... Our neighborhood had a brownout (not a blackout) during the night that lasted for 6+ hours. For whatever reason, every unit's BRKs started beeping during the outage. What's the point of that "feature"? WE KNOW THE POWER'S OUT--save what's left of the batteries. So, over 100 units in the building have their BRK smoke alarms incessantly beeping during the outage. The only way to stop the beeping was to remove the batteries--not the best choice given the need to use candles during the outage... But even after the power came back on, they were still doing the same--beeping in unison. Apparently, they have to be manually reset in a very specific way after a power outage. Holding down the test/reset button for 5-10 seconds will perform a "test", not a "reset"...
How to do a reset: power down AT THE BREAKERS, remove batteries, hold the test/reset for 20 seconds, power up, and install batteries. This routine worked in most, not all, of the homes in the building... The management office sent out e-mails to all the owners with this info, but eventually had to send crews of employees to reset unit owners' systems. (Some loft units have 12-13 foot ceilings). This seemed to resolve issues where both detectors were beeping in unison, but it created another one...
Since the detectors were running for hours on battery power, logically, I & others decided to replace the 3-year old batteries. Big mistake. Now, the BRKs chirp after a few hours with the new batteries. It's beyond frustrating. Three days later, it's 5am, and I can still hear random beeps from various units down the hall. So, the 3-year old batteries are going back in for now... That should stop the beeping for the next few hours...
In a few days, an electrician friend of mine is going to disable mine permanently, and I'll buy regular battery-operated smoke/CO detectors... Enough is enough.
CONTRACTORS & DEVELOPERS BEWARE: These things are cheap, which you'll like. But you run the risk of warranty claims or landing in small claims court, which you won't like. These are poorly designed & engineered and could leave you with liability.
