Will this smoke alarm work if you connect it to your wired home smoke alarm system? If one alarm in your system goes off will this one be alerted?

The SA521CN has a third wire on the power connector to support that. BUT it will only work if the rest of your smoke alarms are also First Alert SA521CN's (one's made recently) or a similar model (the First Alert website lists which other models that the SA521CN is compatible with). It might not work if have SA521CN's that are several years old because some design changes might have been made (you will need to check with First Alert). The later happened to me with another brand of smoke alarms. It definitely will not work if your other smoke alarms are made by another company like Kiddie.

Yes. This unit can send and receive signals to all other wired alarms. In addition, it sends and receives wireless signals.

Don't think it will set off a smoke detector unless it's close. I've used mine inside homes and never had a smoke detector go off.

The house was already wired for the alarm. The old unit stopped working so I had to replace it. All I did was connect the 3-wire plug that extended out from the ceiling into the new alarm. I didn't need to use the 3-wire plug that came with the unit. Sorry I couldn't help more.

I am not sure but I doubt it. This is a hardwired alarm that will activate other alarms that are hardwired with it.

You may need a battery-operated only smoke alarm, like the USI CD-9775 9-Volt Battery Operated Combination Ionization Smoke and Carbon Monoxide Alarm, which you can find on Amazon by typing in B002EVORNY into the search box. Amazon offers other battery-operated smoke / CO alarms by other manufacturers as well. Good luck.

I had this happen twice shortly after my home was constructed and everything was new and I'd moved in. The alarm turned itself off at after 30 seconds. The only thing I could think of is that something new was "outgassing" (paint, plywood glue, etc.). Just to be sure, call your alarm company or an installer of smoke alarms to see if one of your sensors units has gone bad.

Yes you can. Activate the alarm by pulling out the battery protector tab and plug the smoke detector into the existing home wiring. When completed, test the system by pressing and holding the test button for a few seconds and make sure all alarms sound at once.

This unit does not have anyway to connect to a wired or wireless switch system for doors and windows. It only senses a human being physically walking around in the room that unit is located in. Then it does one of two things. #1. Sounds it's siren and dials a phone number(s) and plays a recorded message to alert the dialed party(s) that the alarm has been tripped. Or you can keep the alarm silent and still have the unit silently dial a phone number(s) and play a recorded message to alert the dialed party(s) that the alarm has been tripped. That's it. With an OBI 100 VOIP Telephone Adapter for about $50.00 and VOIP phone service from PhonePower.com for $35.00 per year and using Google Voice (free) to ring my various phone numbers, I have a very inexpensive, very reliable and very effective burglar alarm system for my home configuration. There is another model that has a remote control that might be more convenient for some people or when installing and working with units in multiple rooms. Hope this information helps.

If I unplug the unit, the alarm goes activates. If I plug it back in, the alarm goes off. Hope this helps.

I used this product to test/trigger newly installed smoke detectors. It's one of the best effective product to test and works. I am not sure of your application or what exactly you are talking about.

Yes. Onelinks link. As stated in one of the bullets: "Interconnects with other First Alert ONELINK enabled alarms to create a wireless safety network". Bear in mind that they do not link very far. IE, link them next to each other and then try a mounting location prior to drilling the holes in the wall. Items within the walls like wiring and ductwork block the wireless signal so a slight move may make a lot of difference.

I connected 4 smoke alarms and 2 smoke/carbon monoxide alarms on four floors (basement, first floor, second floor bedrooms and attic bedroom) in my house. I think there's a requirement of fifty feet or less between each alarm, but check the specs. The alarms work well and they're a lot cheaper than hard wiring. My whole installation cost less than $300.

well like any grill, if youre watching and cooking properly you wont have a smoke issue.. I use mine atleast once a week and have had nothing set off the smoke alarm!

fire always brings Carbon monoxide. So if there is fire this will always go off. Can it replace a smoke detector > no just like smoke detectors can not detect CO.

Mine worked just fine out of the box after I instaled the wires to my current alarm. I suggest you check to make sure the batteries are installeld correctly.I do not remember if there were toggle siwtches that need to be set to make it work but I think not. Check to make sure you installed the wires corrrectly in your current alarm.Absent that working, call the help number on your installation document. Good luck. I love mine.

It appears that it isn't. According to the SS-790 manual, "This smoke alarm may be interconnectedwith as many as 11 other UNIVERSAL model smoke alarms such as SS-785, SS-790,SS-795, SS-2795, SS-2895 and 6 other units which may be a combination of CarbonMonoxide Alarms such as CD-9385, CD-9390, CD-9485, CD-9490, CD-9795, Heat Alarms/HD-130 or Relay Modules/RM-100 for a total of not more than 18 interconnected devices."
