## Overview

The Kidde i4618 Firex Hardwire Ionization Smoke Detector (4 Pack) combines reliable ionization sensing technology with a 120V hardwired power source and 9V battery backup.

## Description

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 The 120 volt Firex 4618 Pro Basic smoke detector has an ionization Sensor, quick connect power harness, is multi-station interconnectable, has a 5 year warranty, and is not available to members in Iowa, Oregon Or Vermont.

Review: Good Replacements - OK, to start with, I bought these 4 1/2 years ago. They were direct replacements for my original Kidde detectors that the builder installed in 1995. They installed easily and I basically forgot about them because typical of a good smoke detector, no smoke = no cares. I didn't write a review then because I tend to wait to see if something works before I write a review and as I said earlier, I forgot about them. Anyway, I wanted to write a review today because when I got home from work yesterday I heard a beep. Yep, batteries needed to be replaced. I felt like they didn't last long until I got on the step stool to replace them. I date every battery I install in anything because I can never remember when they were installed. The ones I pulled out yesterday were the ones I installed when I put the detectors on the ceiling. Yes, the original batteries lasted 4 1/2 years. The original builder's Kidde detector batteries wouldn't last 2 years. I'm impressed.
Review: Easily replaced old hard-wired detectors, good value. - These Firex smoke detectors installed fairly easily, even though my ancient original wired-in Kidde-brand detectors use a different base plate and wiring plug. The new base plate installs on standard electric outlet box screws, and the included pigtail plug can replace the old pigtail plug using the wire nuts that are probably already in the ceiling. I also bought conversion adapters between the old and new plug configurations, and that sped up replacement on some detectors, but probably wasn't worth the cost. For new construction, you could use a common wire to connect all your smoke detectors, so that they all go off if one detects smoke. An interesting feature, but I don't really need it. I tested the installed detector with some smoke, and it went off went it should have. I'm hoping that it won't go off as quickly as the last model, which activated every time we fried something on the stove. A good value, especially considering that it also includes a 9-volt backup battery. Hopefully, these detectors last as long as the old ones (20 years), even though I'm now learning that the ionization isotope used decays and is no longer sensitive after only 10 years!

### ⭐⭐⭐⭐⭐ Easy to install!!
*by U***R on November 8, 2019*

All the parts were there for making the wiring connections from the older models to the newer, making the installation a breeze! Took only a couple of minutes for each one, taking down the old detector and replacing the new. Holes were in the right place for the new one to pop right back up where the old came from. The adapter wiring harness was there, didn't need to do any electrical work or turn off power, the connectors went right in and the harness fit in the electrical box. Works great!
