What does this mean ".....interconnect able up to 24 compatible devices": that they can be daisy chained?

I'd like one that could actuate a ventilator or some kind of exhaust fan
Asked by: Marc
Interconnection refers to the "yellow" wire [if so installed already] that is used to tie several alarms [up to 24 for this model] together so that if one alarms sounds it triggers the other alarms to sound for a increased ability to notify occupants that may be down around a hallway or upstairs from the initial alarm sensing point. Do not believe this model would allow for ventilator actuation, believe you would need to purchase that product as a set from a manufacturer.

what does hard wired mean?

Asked by: rt
Hard wire means that there is a dedicated power source for all of the smoke alarms & the battery back up is strictly for the times when the power goes out. Also the third red wire allows that smoke alarms to communicate with each others.

Customer Reviews

AC Hardwired Iophic Smoke/Fire Carbon Monoxide and Natural Gas Alarm with Battery Backup is rated 3.7 out of 5 by 67.
Rated 1 out of 5 by from Awful. False Alarms Galore Had two installed in my home and both failed around the same time. The false alarm is impossible to silence (had to physically disconnect them). Went off at all hours. My dogs are stressed out galore after 6 false alarms in 2 weeks. Home Depot should really reconsider carrying such a lousy product. This is adding to the pile of false alarm reviews.
