Do you know if this unit is interchangeable with Universal Security Instruments USI-1209 120-Volt AC/DC Wired-In Ionization Smoke and Fire Alarm

Sorry I don't. It was an upgrade from what I have but I called universal security and confirmed

I believe so. That sounds like what was originally in our house. I would verify but I turned in all our old ones for recycling. I think I found a list somewhere that had this as a replacement and ordered one to check before ordering the rest of the house replacements.

I'm not sure but you can call USI customer service and they are very helpful. Just call and leave them your phone # and they will call you back.

That depends on the regulations in your area. Maybe ask your local building inspector. My experience was that the connector for the Kidde smoke detector that was already there did not work well with this unit. There were false alarms. It worked well after the correct connector was wired in, but it does not trigger the other Kidde detectors in the house.

If you're replacing one, it's something you'll probably just need a screwdriver for. Just don't touch any bare wires together that aren't already touching. It won't hurt, but could set off your alarm. I'm not sure if it works with all systems, but it worked well with ours.

Even if powered by 120V, the smoke alarm/ CO detector still has a 9v back up battery in case of power outage. The wiring can be attached using the provided connector and wire nuts to attach to house wiring.

I wish! I had 120 in an apartment building and couldn't even begin to tell you of the countless false alarms we've had since they were installed in 2010. I never found one to mix and match with these. If it is hooked into a relay check that too as sometimes that is the problem.

as long as your voltage and amps are same, it should work. I used mine to replace fire alarm panel's batteries.

Yes, but to do so you must replace one of your existing units with/or add one Kidde 1279-9999/RF-SM-AC Hardwire Smoke Alarm with Battery Backup, Interconnectable, to your existing system (assuming that your presently installed devices are a different brand other than Kidde). The Kidde 1279-9999/RF-SM-AC is capable of communicating with the Kidde 0919-9999/RF-SM-DC Battery-Operated devices and will receive/activate alarms from/to other wired units. If you already have a Kidde 1279-9999/RF-SM-AC installed, then you are in great shape, just add the Kidde 0919-9999/RF-SM-DC units as needed.

you can replace it with any smoke alarm that supports your connection, these are great smoke alarms and I stayed with the 1276 units, they are easier to change the batteries in,and they have a great track record.. but its your call any smoke alarm is better than none..hope this helps.

This will work pretty much universally. But, it is not plug and play. You will need to individually tap each wire. There are a lot of sites that provide model specific diagrams for adding alarm systems.

No... This is a Voltage compatibility: 120 VAC device. You might want to try the "kenable Individually Switched 6 Gang Surge Protected Mains Power Extension 2m (~6 feet)". This is rated at Voltage Rating V AC: 230V. Good luck.. cheers

Yes, this unit will work on different circuits as long as they are part of the same grounding system.

I dont know. I just use what comes in the box and it works fine. I suggest that you do not over complicate your systems. Might want to call a electrician if you have electrical and recharging questions, maybe they can check all your other appliances in your home or business as well.

I would not because my units were part of a system that was wired into an existing home security system. I had to find the replacement model for the existing units because 1): some were missing and 2): wanted to do it right the first time. BRK was very helpful with finding the correct upgrade for the orignal units. hope this answers your question

No idea. We haven't had a fire so I couldn't tell you. If it got so bad that it melts the electronics, I would assume you could get a new one sent from Sentry, hook back up and use whatever new code that came with the lock.

Yes. It's quite possible with additional circuitry such as a relay. The problem is; (1) which relay, (2) where do you get it, (3) does it have ample capacity, (4) what kind of enclosure do you put the additional circuitry in, AND (5) will it be safe regarding fire and shock when activated. The guy that said; "it would be better to buy a pre-built unit" is most correct although, I didn't see any "off the shelf" units on a Google search that meet your requirements. It has all the markings of an "electrician required" project.
