We ordered 4 smoke alarms. They arrived VERY fast, especially considering it was a holiday weekend when I ordered. I had to reach out after with a few questions on my end, not theirs they were excellent and fast at responding! I would suggest this company again and again.

I just installed all 6 new smoke alarms. I received wonderful customer service from your staff. In 2013 I used your smoke alarms too. I have recommended your company to my friends.
Worked perfectly as a replacement for an expired smoke alarm. Delivery was sooner than communicated.
These were 10 year replacement units for earlier model equipment which I purchased from you. Had to change the wired in connector, but it was a simple job. Very good quality and an improved battery replacement drawer. Very happy with my choice.
Our smoke alarms were 30 years old and needed replacing. I shopped around for a a device that was for smoke and fires and found this. I was at a better price than the direct replacement for my old alarm and did more. Easy to install.
Excellent product and service
This is the 2nd time buying these.
Was looking to replace 6 out of date smoke detectors after several 6 a.m. false alarms became an early morning headache for me and my family. Checked my local stores to look at different brands and what they offered, but decided it would be easier just to go back with USI. Chose this model because it was said to have the fewest false alarms while being able to accurately detect smoke and fire and so far it has not disappointed. Did have to hardwire this model because its plug specific, but it was not too difficult.
Excellent
Good service and delivery as promised.
Good value for dual unit for detection of 2 different types of fires. Also appreciate the added technology to not trigger a false alarm with common household situations. Easy to install with clearly written instructions.
Work well, easy to replace the old unit with this one.

Excellent service and delivery on time thanks very please to had a business with universalsecuritystore
works great
This alarm really works. It does respond well to even a small amount of smoke. I accidentally burned some food on the stove top and the alarm about 20 feet away started blaring. The only thing to realize is the potential for the smoke to get trapped inside an interior compartment of the alarm itself. The alarm will keep blaring if you reinstall it. When this happens there is no way to blow out the trapped air and the alarm must be replaced by a new one. This, however, could be true for any smoke alarm. Overall this alarm does work very well.
Nice to see that the pin connection remains unchanged from 2011. But for some reason the clamping system has changed from prior model so the ceiling mount needs to be replaced with the new one provided to re-attach the unit to the ceiling.
Easy install and so far have worked good without any false alarms.
Product FAQs
The smoke alarm chirps to indicate a "low battery" condition, meaning the battery needs to be replaced. Battery powered smoke alarms will chirp a minimum of 30 days before the battery completely loses power.
AC powered smoke alarms with battery backup will chirp indefinitely assuming AC power is present; if battery power is low, or battery is removed; until a fresh battery is installed. Approved replacement batteries are listed on the back of each smoke alarm and in the user's manual.
Certain model smoke alarms with a silence button (designed to silence the alarm during a nuisance alarm) may chirp to indicate the smoke alarm is in the silence mode. The chirp will stop after approximately 8 minutes and the smoke alarm will return to its normal operation.
The flashing red light gives a visual indication that the smoke detector is functioning properly. It also indicates a working battery is connected to the smoke alarm.
When a green light is present on your smoke detector, it means that AC power is currently operating the alarm.
If the green light on your smoke detector is not on, it means the AC power has been interrupted to the alarm. Check the circuit breaker and AC wiring to make sure power is still reaching the smoke alarm.
When interconnected alarms are alarming, the smoke alarm which initiated the alarm, either by test button or sensing smoke, will flash the red LED light approximately once per second. The red LED light on the other non-initiated interconnected smoke detectors will not be lit but will sound the alarm.
The NFPA 72 standard states the interconnect limit is 12 smoke alarms and up to 6 other alarms (heat alarms or carbon monoxide detectors) for a total of 18 total alarms. With 18 alarms interconnected, up to an additional 6 relay modules may be interconnected (for a maximum of 24 devices).
If battery backup alarms and non-battery backup alarms and accessories are mixed in an interconnect system, all devices without battery backup WILL NOT operate during an AC power failure.
CAUTION: USI alarms and accessories should only be interconnected with other USI alarms and accessories. Connecting devices from another manufacturer to USI devices may result in nuisance alarms, failure to alarm, or damage to one or all of the devices in the interconnect system. All interconnected USI alarms should be powered by the same fuse or circuit breaker. Smoke alarms shall not receive their power from a circuit that is protected by a ground fault circuit interrupter. Improper connection will result in damage to the alarm, failure to operate, or a shock hazard.
