I am planning to buy 3 items to my country where the electricity works with 220 Volts AC .is it possible to use it permanetly with the 9V battery?
Asked by: Gazzi
No pure battery operation. The detector can only be operated with 120 volts and a 9V backup battery. Please inform yourself about the rules in your country which smoke detectors are allowed.

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?

I installed these devices several times and can recommend these devices with a good conscience. The price is unbeatable.

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?

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.

Rated 2 out of 5 by from Replaced 3 of 4 I have 4 of these in my house, and my house is 16 month old. I have had to replace 3 of the 4 already as once they go they go out with the full squeal and there is no stopping it until you take it off and pull the battery out. They are easy to replace, but not sure why they malfunction so quickly. I have 6 more of the same brand in my house but they are fire protection only units. Not one of those has malfunctioned. All are hardwired.

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.
