Customer Reviews For The USI Hardwired Ionization Smoke Alarm with Long Life Battery Backup 5304L
Overall Rating
Product Reviews
House was built with USI interconnected smoke alarms installed. Time to replace them, so I chose the 5304Ls with the ten-year battery for convenience.
Longer life batteries make maintenance easier.
These were easy to install as replacements to Model 5204 Smoke & Fire Alarms, because of using existing wires & plug-in.
Installed without any issues. No apparent defects. Would buy again.
Very simple to install. The alarm replaced model 1204 and the base fits easily into the old ceiling fitting. USI has taken care to make sure the upgraded new devices can be used in the same location as the previous models.
Detectors were ordered to replace expired units. Installation was straightforward.
I ordered online, based on reviews and comments, the model I thought would replace my smoke alarms since they all went off at one time-my experience told me they had reached the end! Come to find out, I picked the wrong one! I called the company and they immediately advised the correct unit, placed the order for me and sent me RMA paperwork for return! All in just a few minutes! Wonderful customer service! I highly recommend this company!
VERY NICE PRODUCT AND VERY PLEASED WITH ENCLOSED WIRING TO MATCH AND MOUNTING PLATE YOU REQUIRE FOR INSTALLATION.LONG LIFE BATTERY IS SUPER VALUABLE TO ENHANCE PRODUCT !
Shipped promptly, easy installation, works as advertised.
At 70 I don't want to be climbing ladder to change batteries. Good idea making them last longer
This is the second time I have ordered replacement smoke detectors for our home. The replacement items have worked very well. No failures nor problems of any sort. Great products from a great company!
Easy to install. Arrived in a timely fashion.
It's a smoke detector with integrated charger and a rechargeable battery promised to last the life of the detector, which makes changing batteries obsolete. If it will last the 10 years as promised, it will be a great device!
Excellent replacement for older alarm model 1204 to retain inter-connectivity with a 10-year battery life.
Time to replace the 5-year-old alarms. These were perfect, brand-for-brand, with the added convenience of fitting the existing brackets!
Very pleased with our recent purchase of smoke detectors. Order was processed quickly and provided in record time.
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.
