Question: We have 16 smoke locations will these interconnect with that many locations
Document: The Onelink SCO500 will not identify locations with Hardwired Onelink SA520 (SA521CN). You can't even setup locations like the Manual Implies.SA520 "QUICK INSTALLATION INSTRUCTIONS""8. If you purchased the Talking Smoke and Carbon Monoxide Alarm, youwill now be prompted to set the Alarm's location. Follow the directionsgiven by the Alarm.9. If you have purchased the hardwired battery back-up ONELINKTM Alarm,you can now connect the hardwired Alarm by installing the three-wireconnector on the ceiling to the Alarm.10.
Installed easily. Have to be sure and read the directions when linking, but it's not too difficult. Much cheaper than running signal wires between locations. A recommended product.
You should only need only one of this model and then combine it with unwired ONELINK units in your new locations. Worked perfectly for me and only took a little over an hour to add 3 new alarm locations.
I have 7 of the First Alert SA520 Onelink units that were installed in my home 2.5 yrs ago. They were easy to set up although getting power to each unit in an older, 3-story home was the biggest challenge. They link to each other well. You may wish to install them in a particular sequence if using many of them on different floors.
"I'm writing because seeing you jogged my memory that our fire alarms have gone off 3 more times since you took the batteries out on the 3rd floor [temporary measure that leaves the hard-wired functioning of the hardwired units installed, still in place]. What can we do about this? Is it a manufacturer's problem? I sincerely don't think we have many bugs climbing across our fire alarms at regular intervals. What can we do?
Bought 6 of these to replace my 13-year old BRKs. Easy to install. The wireless "mesh" interconnect feature was very easy to set up and seems extremely well designed. [The sensors in your "mesh" all recognize and talk to each other so that any sensor can trigger any or all the others, but they all ignore any sensors not programmed into their little network, i.e. they supposedly ignore the neighbors sensors.
It does not need to be able to reach all others...they will relay the alert.] They can also easily link into any existing hard-wired interconnect system in addition to the wireless.Also I like the combination of battery backup and hard-wired power.I also like the one button operation. Press the button to test, and press it again to silence any alert. So far so good.
I bought these due the the hard-waring, battery backup, and linking options. Setup was relatively straight forward, and installation was easy due to pre-existing 120vac wiring for older detectors. Testing ensured they were linked.Something else not mentioned in many reviews is the desirability for a photoelectric detector. There is a lot of information out there indicating ionization detectors have severe drawbacks in detecting smoldering energy sources which ultimately lead to fires.
The smoke alarms were pretty easy to install and seem to link up nicely. They are a welcome addition to our sense of security.
I forgot to install the third wire for the smoke alarms so this product worked great. Easy to set up.
