Product Reviews
I purchased 5 of these alarms and they were easy to install. They are electrical and came with a backup battery. I would recommend them to anyone.
I replaced all my house's smoke and fire alarms with the 5304 ones and haven't experienced any issues.
Great product to replace outdated alarms. Easy install and perform flawlessly
very good shipping service
Just replaced three model 5304 alarms that were 10 years old. Did this because of age. They worked fine for the 10 years.
The model 5304 alarm has worked flawlessly for 10 years. Well priced and good service.
Didn't know I had to ever replace these but upon changing the battery on an original one that came with the house, it said 2004 and replace every 10 years. I ordered these as the new replacement for the old part number. Came as promised. I had to rewire the connection to fit the new plug design. Came with 9 volt batteries. 9 of the 10 went in smooth but the 10th one set off the other 9 after rewiring twice. I swapped it with the 9th one and it solved the problem. Not much else to say. I tested them and they beep. Hopefully good for another 10 years.
We have been getting our smoke detectors here for years and have never had any issues. Always quick delivery & have not had any issues with the product.
I appreciate their customer service. They are so helpful ,friendly and professional. Their prices are better.
Very easy to order and shipped right away. All products were in good shape. Will order from you again. THANK YOU !
The fire alarms were very easy to install but the harness changed slightly between the 5204 and 5304 models. The mounting bracket also had to be replaced as they were slightly different. If everything was same, it would have been just unhook and plug-in.
The little suckers were tricky to twist-snap together once up on the ceiling. Sure would have been nice if the screws were included as well. Otherwise they units arrived timely and weren't very expensive for replacements.
Purchased this item to replace two units previously installed by the builder of our home and that had reached their lifes end. The units were extremely easy to install. Only had to change out the mounting plate.
smoke alarms arrived in good order, everything was in the package, non damaged and all work fine.
Simple easy installation. Simple readiut
Yes I installed this item at a clients home yesterday easy install and setup
I did receive this product as promised. I installed 6 of them without any trouble. I am not an electrician. I am satisfied.
The product arrived quickly and was simple to install. It was used to replace an alarm that had gone bad, due to age.
Easiest upgrade for expired smoke detector
Bought these to replace existing! Very easy to install and the access to replace the battery is simple. They are pleasing to the eye.
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.
