My original USI smoke detector worked flawlessly for years. Now the new one pops right into the old base without a tool of any kind. Great

Found the item. Ordered so fast. Exact fit without having to replace the base or rewire. I know my home is safe from smoke alarm failure for another 10 years minimum. The ones I replaced were actually 13 years olds, but stick to recommended 10 year. Too easy to replace to be uncertain.

When I bought home 10 years ago, it came with USI-1204 Model. I never had issues with these. I decided to use the same model so don't need to replace entire set. I just can replace only top part. Quality product with reasonable price. USI should think about selling only top part for people who just want to replace with the original model. I used only top part and there is no use of the base.

My house was built in 2007 and my 7 smoke alarms starting going off randomly. As we know smoke alarms do expire. I was satisfied with the alarms that came With the house so I googled the manufacturer and found Universal Security. The 7 alarms were sent ASAP in brand new boxes and they fit perfectly. I'm good for another 10 years, thanks Universal Security.

Purchased as replacement for 12 year old alarms that still working, but figured there lifespan was limited and I was replacing the 3-in-1 alarms, so just as well update them all. Easy to install and work great! Peace of mind with little work at a reasonable price.

Works as advertised. Have used this model for several years. Recent lightning strike fried 2 of 5. Base still the same. Just plug in new units and all is good. Highly recommend.

Q: WHY DOES MY SMOKE ALARM 'CHIRP' APPROXIMATELY ONCE EVERY MINUTE?
A: 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.

Q: WHAT DOES IT MEAN WHEN THE RED LIGHT ON THE ALARM FLASHES APPROXIMATELY ONCE EVERY MINUTE?
A: 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.

Q: WHAT DOES THE CONTINUOUS GREEN LIGHT ON MY SMOKE ALARM INDICATE?
A: When a green light is present on your smoke detector, it means that AC power is currently operating the alarm.

Q: THE GREEN LIGHT ON MY SMOKE ALARM HAS GONE OUT, WHAT DOES THIS MEAN?
A: 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.

Q: HOW CAN I TELL WHICH SMOKE ALARM IN A MULTI-STATION SYSTEM INITIATED THE ALARM?
A: 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.

Q: HOW MANY SMOKE ALARMS OR DEVICES CAN BE INTERCONNECT AT ONE TIME?
A: 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.
