Can this combo unit take the place of an existing hardwired first alert fire only alarm?

I have replaced one of my hardwired fire units on my own with no problem; is the wiring the same with adapter or will i need an electrician to re-wire the unit or units?

Asked by: Jan
Hi Jan, thank you for your recent inquiry with The Home Depot. Unfortunately, due certain regulations and restrictions put in place by your state we are unable to ship the 120-Volt AC Hardwired Ionization Smoke and Fire Carbon Monoxide and Natural Gas Alarm to California. We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot.

2 wire connection

The suggested replacement for the USI 7795 with a three wire connector is the MICN109 however the specifications of the connection indicates that it is a two wire. Do I need to make some wiring modification?
Asked by: Jk48
Only if it is to be linked to other detectors.

Good consistent alert performance. USI has a broad product line to choose from when adding smoke, CO, and LP/natural gas alarm systems. Would chose USI for future purchases.

I thought I could just plug it in, but this isn't working. When I plug it in, the alarm goes off, and then the other 5 alarms go off too. How can I fix this?

Rated 1 out of 5 by from Failed in 18 mos, terrible manufacturers warranty The electrician helping with my basement remodel bought the detectors from Home Depot in Feb15. The Manufacturer wanted me to send the defective item with a check for $11 and then wait for them to send a replacement, not even specifying if it will be new or reconditioned.

The detector was fairly easy to install but getting the detector to affix to the base was problematic. I thought i had aligned everything properly but it seemed more difficult than normal to have the holes line up and the detector lock onto the base. Additionally, the 9 volt battery supplied with the detector was DOA and i had the detector chirping as soon as it was installed, necessitating a new battery that i had to supply.
