Questions & Answers

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.

Can i wire a plug, and literally plug this in?

Asked by: Wilsonswoodworks
To answer your question simply-no. These are made to be used in a conjunction or with a series of other same type units. The units require a 3-wire installation that goes to each of the units, thus with the 3rd or RED wire of the 3-wire system the units communicate with each other. The 3rd wire allows the units to signal that there is smoke, fire, or a gas leak at the proximate point of one of the units to the other units, this is done to alert the user of a problem that is remote from where the user is at the time. Hope this answers your question.

AC Hardwired Iophic Smoke/Fire Carbon Monoxide and Natural Gas Alarm with Battery Backup is rated 3.4 out of 5 by 31.
Rated 1 out of 5 by from Worst alarms These smoke detectors are awful. They go off whenever we turn on the oven and hitting the “silent” button doesn’t stop them. Many times you just have to wait until they go off. Worst alarms I have ever experienced.
