Installing a smoke detector costs between $70 and $400 per unit, with prices heavily depending on whether the unit is battery-operated, hardwired, or a smart device.
The national average cost for installing a smoke detector is between $70 and $150, with most people paying around $112 to install a dual hardwired detector. At the low end of the spectrum, you pay around $44 for a battery-operated ionization detector.
The short answer is this: sometimes you can replace a hardwired smoke detector yourself, but many homeowners should call a licensed electrician to make sure the replacement is safe, compatible, and working properly. That matters because hardwired smoke detectors are tied into your home's electrical system.
The advanced technology in the Cove smoke detector is designed to sense smoke early, saving you money and getting you help quickly.
Some fire departments offer reduced-price, or even free, smoke alarms. Contact your local fire department's nonemergency phone number for more information. Your city, county or state may require a specific type of alarm. Please check with your local fire marshal for information on what type of alarm you need.
The US National Fire Protection Association (NFPA) have issued NFPA Standard 72, National Fire Alarm and Signalling Code, which states that all smoke alarms (including alarms that use 10 year batteries, and those that are hard wired) should be replaced when they are ten years old, or sooner if they don't respond ...
Alternatively, for the most vulnerable, you can apply for a Safe and Well visit from us. During the visit, our local firefighters will give you safety advice on a range of areas such as fire and personal safety as well as fitting smoke detectors free where they're needed.
Cove keeps it simple with two main tiers: Cove Basic: $19.99/month — Includes professional monitoring but no smart home integration. 1-year warranty. Cove Plus: $29.99/month — Offers both smart home integration and professional monitoring, with a lifetime warranty.
For the best protection or where extra time is needed to awaken or assist others, both ionization smoke alarms and photoelectric smoke alarms or combination ionization-photoelectric alarms are recommended.
Whether SimpliSafe or Cove is better depends on your specific needs, but SimpliSafe is generally the better overall choice for most homes due to its wider variety of equipment, stronger smart home integrations, and flexible monitoring plans. However, Cove is a highly competitive, budget-friendly alternative that excels in ease of use and upfront pricing.
For a 3-bedroom house, you need at least 5 smoke alarms. The National Fire Protection Association (NFPA) requires alarms in three specific locations for maximum safety:
If your home was built after 1986, it will have at least one hard wired smoke alarm connected directly to your electrical panel. It is not acceptable to replace a hard wired alarm with one that is battery operated. A home must maintain at least the same level of protection as originally required. It is the law.
Place smoke detectors at the top of each stairwell and at the end of each long hallway. Smoke rises easily through stairwells. If you should put a smoke detector in your kitchen, be sure to keep it away from cooking fumes or smoking areas.
An electrician is trained to handle electrical wiring safely and is knowledgeable about local building codes. In many cases, you'll want to hire an electrician for proper installation—especially for hardwired smoke detectors, which require knowledge of electrical systems and wiring.
Labour Costs and Timescales
Fitting a mains-powered alarm requires a qualified electrician. Most charge per alarm fitted, with labour typically ranging from £55 to £100 per alarm. You should expect the work to take 1 to 2 hours for the first alarm, with an extra 30 minutes for each additional alarm.
Using a keypad and a base station from a SimpliSafe system, and an off-the-shelf microcontroller — all of which cost roughly $250 — Zonenberg demonstrated how easy it is for a burglar to disable the alarm.
SimpliSafe is widely considered the overall best home security system. It offers the ideal balance of beginner-friendly DIY installation, no long-term contracts, and robust 24/7 professional monitoring.

To a firefighter, 5-5-5 (most traditionally known as 5-5-5-5, or "striking the four fives") is a solemn, time-honored bell signal used to honor a firefighter who has died in the line of duty.
Yes, you should get a combination smoke and carbon monoxide (CO) detector, as they save space, simplify maintenance, and reduce the number of devices you have to manage. They are highly recommended for covering two critical life-safety needs in one unit.
Cove and ADT represent two very different approaches to home security.
Yes, visible security cameras strongly deter burglars. Studies by the University of North Carolina found that about 60% of convicted burglars deliberately avoid homes with clearly visible security systems and cameras to reduce the risk of being identified and recorded.
No, you cannot use a Cove security system without a subscription. Cove does not offer a free or self-monitored tier. Its equipment and app require an active 24/7 professional monitoring plan to function.
