The unit is hardwired to your household power. The battery is for back-up incase of power outage.

The Kidde KN-COSM-1B 21006377 is a unit that shout be hardwired to the house 120V hardwired fire/CO protection system. The unit is backed up by a 9V battery (in case the house power fails). If you are replacing a hardwired unit you should see the previous 3 wires and connecton. If the old connection does not fit to new Kidde, replace it with the connection provided in the new unit box. If you cannot see the old hardwired connection, the old unit was not hardwired but only battery operated. In this case either you should return your Kidde unit and ask for a different model ( also cheaper). If you still want to have a hardwired unit, I recommend that you to bring in a professional.

Even if powered by 120V, the smoke alarm/ CO detector still has a 9v back up battery in case of power outage. The wiring can be attached using the provided connector and wire nuts to attach to house wiring.

the battery is for backup only..... in case electricity goes out. You still need to wire it.

I was surprised to find that the 2 motion detectors in the HA-300 kit that I received on 10/15/2015 are powered by 2 AAA batteries. The instructions still say 9 volt. So far seems to work as advertised (40 feet and 110 degrees). 9 volts down to 3? Wonder how long they will last? Much easier to change than 9 volt.

The ones I have are 120v single phase. Wish they were 220v. That is standard here so have to use an inverter. I am using them in a factory in the Philippines on a tracer machine. They have been run hard 6 days a week for 6 months with no problems.

The User's Guide for this product, and stamped on the item itself, are model numbers of alkalines, (Duracell MN1500 or MX1500; Energizer E91, etc). However, it does say "Use of a different battery may have a detrimental effect on the alarm operation." Thank you for calling my attention to this, because the rechargeables I use are NiMH. The item comes with batteries.

They're 120v. You may as well shop at Amazon UK where 220v tools and appliances abound.

I don't know. I asked questions at a recent safety fair to local firefighters. They gave me a sheet with explanations of the types of fire alarms and the features of each one. I am not sure what model was in our home, but do know it was standard, builder-grade and was hard-wired with a battery back-up.

These are 12 volt not 120 volt! With that said you could use a 12 volt DC transformer or a 12 volt battery

I wouldn't think it matters at all. I have never seen this low a rating- are you sure it isn't 3 amp or 2.5amp ? either way is shouldn't matter- there is probably a fuse to insure no overload. BTW- the one I bought seemed to work for 30 seconds and next thing it wasn't supplying any power at all. I never returned it , just used the old one that wasn't really bad. My alarm system needed a new battery and a fuse.

Regardless of what vehicle it's in or if it's running packs in parallel or series I've always stopped at 3.6v/cell when the pack is at rest. You could possibly go lower and still be safe, however I noticed that my packs lasted a lot longer stopping at 3.6v/cell. Also I found these alarms to be rather quiet. Just a heads up. Enjoy &#128522;

I do not know why in the product information it states 20v but I have had this unit for 6 months now using my 18 volt porter-cable batteries ....it works great

Ms. Kittay, I suspect you are trying to buy the smoke alarms from the same vendor I did. First of all, they do not come with an adapter. Secondly, I bought a package of 6 from the vendor to get a cheaper price. However, three of them started beeping (acting they were faulty) right from the start. My guess was that they were not "new" and might have been refurbished, although I was under the impression I was purchasing new products. So, I would instead try going to your local hardware store for these items. That way, you can return them there a lot easier (and cheaper) if they do not work out. I hope this helps you. Regards

The box says 200ma at 12vdc which is 2.4va. Personally, I use a 12v battery (NP4 - 12V, 4.0ah) with a 300ma charger attached to it to power my whole alarm system, of which the alarm siren is a part. The charger is a simple 12vdc adapter that plugs into the 120 vac outlet. The purpose of the charger is to keep the battery charged, while the battery is expected to do the heavy lifting for powering the siren, buzzers, etc. If the siren is a part of an alarm system, you would want the battery to be the main power supply in case the electricity is disrupted for some reason.

Mine is 120v ac, I guess they come in 240v also for our friends across the pond, make sure you know what your ordering.

There are no specs on the switch or package. These look like a typical alarm type of switch, not meant for much current. It would be all right if you are doing a low voltage (25 volts or less) DIY because of the small contacts and exposed terminals. If you are using a commercial 120 volt light, check the power needed and somehow shield the terminals from people touching them or use the switch as a low voltage control for the 120 volt at the light.

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.
