Peak memory Indicates whether a model shows peak levels that have occurred.
The home we are renting is beautiful- but has a million of these smoke detectors that we have grown to hate. We change the batteries CONSTANTLY- and have had to change the batteries on the same unit on occasion although we have been in the home a year. Changing the batteries is difficult. Several grown men have changed them and sometimes it works- sometimes it doesn't and the unit just keeps on beeping. Occasionally we have totally removed the unit, the placed back on and it worked. As I'm writing this we have one that's been beeping for 24 hours despite a brand new battery. A major cause of stress and I can't wait to move to a home with none of these nightmares.

Comment:
After an incident caused by an improper vent installation in my basement, I installed a pair of these: one at the top of my stairwell from first to second floor where it is useful for all the sleeping areas, and one in my basement near the furnace and water heater. I have yet to get them properly linked- if the upstairs is activated it occasionally links to the basement-if the basement is activated it never links to the upstairs. I have constant false alarms from the upstairs unit where the alarm sounds but no voice comes on. I was told by the customer support line that there must be something interfering with the link even though it works intermittently, and also said that sometimes units downstairs can't link to units upstairs, but upstairs units can link to downstairs units - I have no idea what that means, and I'm not sure I was understood, since they also suggested that the upstairs unit was full of dust and needed cleaning. Although it appeared clean I used canned air to clean it as they suggested, but no change in performance-still very poor. They said try all these things and get back to them and they would see if the warranty covered it. I would think they should know that. Horrible product, terrible service. Disappointed with this company.

Comment:
We installed these when we finished the basement 18 months ago. The area is now bedrooms and rec room for pre-teen aged kids. The voice alarm is fantastic because it tells them what to do i.e. exit the area and they do! <br />I am now replacing the alarms in the rest of the house with these. I have read that they were too sensitive but in 18 months have had 0 false alarms with these. The false alarms were from older detectors in other parts of the house which has a hard wired system.<br />I also love the fact that these use AA batteries and not 9 volt! With four kids we always have AA's hanging around and don't have to make an extra trip out to get 9 volts!

First Alert ONELink Smoke and Carbon Monoxide Alarm w/ Voice Location
12/03/2007
Strength
Two in One and wireless communication
Weakness
none
This would be a good choice if you have a multi-level house. I hook up 3 alarms on each floor and they communicate to each other like a charm. You can't go wrong with this product when there is a fire or carbon monoxide going on.
Incredibly easy to install, easy to setup, easy to link and program, voice location
Weakness
none
In looking to replace the smoke and carbon monoxide alarms, the idea of Onelink seemed great. So I bought several of these. Got home, and installed each alarm in about two minutes - it was that easy. Another thirty seconds each to program the location, and about 15 seconds to link each alarm. It was that simple. Bottom line is at the first sign of smoke, EACH alarm will begin to sound, as they are all linked to each other via a wireless connection. It will be virtually impossible to ignore eight alarms going off throughout the house. And the location will also be announced. What could be better than that?
