Untitled Document

The Firex i4618 Hardwire Smoke Alarm by Kidde is an ionization smoke alarm that operates on a 120V power source with 9V battery backup. The Firex i4618 smoke alarm offers many benefits for installers and homeowners, such as its easy-access slide load front battery door.

This alarm is powered by your home’s electricity and will interconnect with other smoke alarms in your home. Experts recommend interconnected alarms, because when one sounds, they all sound, providing an early warning against fire by dramatically increasing your ability to hear an alarm anywhere in your home, regardless of where the fire starts.

This alarm uses ionization sensing technology. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fire that can occur within the home.

  • Easy access front loading battery door.

Interconnectable for Improved Safety
Fire and consumer experts recommend interconnected alarms for added protection. According to the National Fire Protection Association (NFPA), most Americans feel they are more at risk of being a victim of a tornado than of a house fire. Actually the opposite is true. Fires are more common than any other disaster that strikes a family at home, and can become deadly in minutes.

You have on average less than three minutes from the time you hear a smoke alarm to escape a fire. The sooner you hear an alarm, the sooner you can get out safely. Smoke alarms that link together so that when one goes off, they all go off, are called interconnected alarms. These alarms provide more warnings in more places, giving your family more time to escape a house fire. Houses built after 1993 are required by building codes to have interconnected alarms that are wired into their electrical system.

Interconnects with Other Devices
Interconnects with all Kidde, Firex, Fyrnetics, Lifesaver and Nighthawk alarms, strobe lights, and relay modules with interconnect functionality.

Trademarked Hush Feature for Convenience
By pressing the Hush button, you can easily and safely silence nuisance alarms caused by non-emergency situations, such as overcooked dinners.

This alarm's Smart Hush feature has the capability of temporarily desensitizing the alarm circuit for up to 8 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm. The smoke alarm is desensitized by pushing the Test/Hush button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately. The red LED will illuminate for 1.5 seconds every 8 seconds while in hush. This indicates that the alarm is in a temporarily desensitized condition. The smoke alarm will automatically reset after approximately 8 minutes and sound the alarm if particles of combustion are still present. Smart Hush can be used repeatedly until the air has been cleared of the condition causing the alarm. Pushing the Test/Hush button on the alarm will end the hush period.

Reliable 9-Volt Battery Backup, Indicator LED, and Test Feature
Because a smoke alarm only helps protect you if it's working, this unit features a red LED that flashes every 30 to 40 seconds to indicate that it is operating correctly. For additional peace of mind, the alarm also contains a test/reset button that enables you to periodically test its circuitry and horn.

The alarm’s standard 9-volt battery provides continuous protection against smoke and fire hazards, even during power outages. The unit offers a low battery warning that issues a brief chirp every 30 to 40 seconds for at least seven days before losing power, letting you know that it's time to change the battery.

The unit measures just 5.6 inches in diameter and 1.8 inches deep, and it features a neutral, white finish. It includes tamper resist features to deter vandalism or theft.

This alarm is UL listed, so you can be confident of its quality, and it is backed by a 5-year limited warranty.

5.0 out of 5 stars Excellent Buy, December 28, 2007
By FCast "FC" (Long Island NY) - See all my reviews
This product was easy to install with very clear instructions. I installed it in 10 minutes as a replacement to an older unit which had expired. These units should be replaced periodically and some have expiration dates on them..

4.0 out of 5 stars Avoid the beeps: be very careful installing the batteries, July 9, 2009
One reviewer criticized these detectors for intermittent beeps. Here's probably why. The 9v batteries have polarity but the contacts are metal springs, not the snap-in contacts we are more familiar with for 9V batteries. The +/- markings are small and inside the case, so it is easy to miss them and to put a battery in backwards, especially once the unit is mounted in some hard-to-reach place like the ceiling. If you switch the polarity when replacing a battery, you may be setting up for a problem, and for some reason I don't understand this may not happen right away but only many days later. This can happen even if all of the batteries are put in the same way but with reversed polarity. The polarities of the batteries must match the markings or these units may beep often and intermittently (I believe this happens only with interconnected units).

I give this product a less than perfect rating because it is so easy to insert the batteries backwards and so hard to read the correct polarity. Furthermore, I found no mention of those polarities anywhere in the user guide; that advice should have been in the troubleshooting section. But these are otherwise very effective detectors and if not for this problem I'd have rated them as a 5.

5.0 out of 5 stars Number ONE Contractor Installed Smoke Alarm in the US, June 3, 2009
By Big Kat "Big Kat" (Daytona Beach, Florida) - See all my reviews
My smoke alarms were more than 10 years one so I wanted to replace them. Once I started doing research I found out from 2-3 contractors that this is the number one installed smoke alarm in the US. So I ordered 7 of these from Amazon and it was "plug and play". I did not even need a screw driver! My wife was very happy.
If you have a smoke alarm that looks like the one show in the Amazon pictures (and it is a good chance you do) then order them and it should be simple to install / replace.
