BRK 7010B Photoelectric Smoke Alarm: If it is inconvenient to hardwire this smoke alarm is it acceptable to operate as a battery only smoke alarm?

Hello Ron, It would be best to purchase battery-operated smoke alarms. Best regards, Tim McGreal, P.E. Fire Protection Engineer Inventor of the Alarm Arm No Ladder Smoke Alarm www.AlarmArm.com Alarm Arm 110-00 No Ladder Smoke Alarm System

Hello,These smoke alarms are wireless, and do not need A/C Power. They run strictly off of the 9V battery.Thanks!www.FortressSecurityStore.com

The last time I researched the dual alarms were not available in battery operation. They are only made to be hard wired because the dual capability needs more power than batteries can provide. The battery operated ones that I bought are VERY sensitive and work VERY well on all 3 floors of our home.

You can hard wire these, but that can cause a fire if the wires were ever to short-circuit. I would suggest putting a fuse in the circuit to prevent any problems.

Smoke Alarm side is photoelectric only. To have the ionization detection, you must purchase an additional alarm. Keep in mind that there is a maximum number of alarms that can be connected together.

I answered this several weeks ago, and I just checked the site and for some reason Amazon didn't post it; their bad! All of my smoke alarms were hard wired as per code. But if the 9v back up battery in one died, all of the alarms went off; I was up all night one night. Anyway, my old ones were not Kidde, but the Kidde replacements fit perfectly.Go to: www.kidde.com and find their Customer Support 800 #. They were very helpful when I called them. Good luck, and I am sorry my first answer was not posted; I have no idea what happened. navydoc

I saw this alarm on a news program as the most reliable smoke detector available. I gave one to each of my kids, they've never had to be used so I cannot answer your question, I am very sorry.

I unplugged mine and threw it away because it gave many false alarms. The unit, and others like it according to comments on the Internet, are too sensitive. Hair spray, perfume, etc. may set off the alarm. Many pressurized cans use propane as the propellant, so it's not actually a true false alarm because propane is in the air but all that beeping was too much to deal with.

Adding Kidde alarm units to an established circuit has never been easier than with the Kidde RF-SM-AC. This hardwired wireless interconnectable smoke alarm with battery backup can expand your current coverage by simply replacing an interconnected alarm and adding the Kidde RF-SM-AC. Once this unit has become part of your circuit, you can add as many Kidde wireless smoke alarms as are necessary to expand your realm of protection. No wiring is required to install this device, as you can simply mount it on any wall or ceiling to start expanding your Kidde alarm circuit. If the alarm sounds to alert you of a possible fire hazard, the wireless technology of the Kidde RF-SM-AC will spread the alarm to the rest of your circuit, warning you no matter where you are. This device is UL listed and compatible with any Kidde alarm devices, allowing you to create a wide range of protection no matter the size of your area. One last thing just make sure you set all the same codes in all your wireless smoke detectors.

the 2 old units I replaced were Lifesaver Model 1255 - I think most units are standardized to communicate over the 3rd wire so all alarms connected together sound when any one goes off. If you don't require that feature, I think any standard 2 wire unit can replace any other. See this link to help in deciding if you want photo or ion (or the combo unit I bought) https://www.nfpa.org/safety-information/for-consumers/fire-and-safety-equipment/smoke-alarms/ionization-vs-photoelectric

This model requires you to have battery backup and is designed for your safety. CO poisoning is most likely to occur during power outages, and without a battery backup you would not have a functioning CO alarm.

Yes, but to do so you must replace one of your existing units with/or add one Kidde 1279-9999/RF-SM-AC Hardwire Smoke Alarm with Battery Backup, Interconnectable, to your existing system (assuming that your presently installed devices are a different brand other than Kidde). The Kidde 1279-9999/RF-SM-AC is capable of communicating with the Kidde 0919-9999/RF-SM-DC Battery-Operated devices and will receive/activate alarms from/to other wired units. If you already have a Kidde 1279-9999/RF-SM-AC installed, then you are in great shape, just add the Kidde 0919-9999/RF-SM-DC units as needed.

any high quality, i.e. duracell or energizer alkaline battery, just remember to replace it before it starts to beep. When you wait for it to start beeping, you usually pull the battery and don't immediately replace it, which defeats the purpose of a smoke detector. I change mine with fall daylight savings time.

Kidde sells photoelectric alarms with the sealed 10-yr battery that are very good, they just aren't interconnected. They also have a combination I/P alarm that does both and is interconnected. That one hard-wires though and has a battery backup. If your home is hard-wired then that's the way to go.

The SA521CN is designed to operate as hard wired with other wired smoke alarms,and also connect to wireless "One Link" First Alert alarms. If hard wired you get power from the 110 volt connection. It also has two AA batteries which work when the power is off. There are other wireless models of "One Link" that look similar, use two AA batteries, and wireless connect among themselves and the SA521CN. I alrady had a hard wired system with First Alert connections. I purchased only one SA521CN to replace an existing hard wired only alarm, hard wired it, and also purchased some "One Link" alarms that operate only on two AA bateries. By having ONE SA521CN hard wired, if any alarm goes off--wireless or hard wired only, then ALL hard wired AND wireless alarms go off. Responding directly to the question, I assume this can be used strictly as wireless without a short battery life, but there are other models specifically operating on two AA only. I don't know if the battery life would be shorter on theSA521CN or not, but it will work..

This is a hard-wired alarm w/ battery backup. For a dual alarm powered only by battery, look for First Alert SA320CN Double Sensor Battery-Powered Smoke and Fire Alarm
