USI Electric Hardwired Ionization Smoke and Fire Alarm with Battery Backup (5304)

Great Product for Great Price! - 02/16/2018
Reviewer: Nina House
I always knew that I should replace the batteries in my Smoke and Fire alarms but I then found out that the units themselves have an expiration date. USI offers a great product for a great price! I was able to order online from USI a bundle of 4 Smoke detectors. Shopping was easy and shipping was fast!

Had one in my house for 22 years before it quit working. Replaced it with a new model and it plugged right in. Had a little trouble with getting the alarm to align/twist into the bracket on the ceiling.

Reviewer: VICK D
I ordered 5 of these smoke alarms to replace the 10-year-old models in my home one started malfunctioning and I decided to replace all of them. I am not experienced enough to install new electrical wiring. Online research showed this is the replacement model for the old fire alarms. This model allowed me to use the same mounting bracket and quick connector wire for the electrical hookup. The quick connector was a little difficult to remove but after the first installation, I'm a pro! Ordering was easy, the product is reasonably priced,and it arrived quickly. I plan to order my next replacements in 10 years when these need replacement. AWESOME.

Minor Rewiring Reqd - 04/17/2017
Reviewer: Vic Hackenschmidt
I replaced 7 hard-wired units in an hour and a half. The old plugs weren't an exact fit on the new units, so I had to wire in the new pigs. Old units were 11 years old. New 5304s work perfectly.

I had an older model Universal smoke alarm. When doing the research their site said the replacement model was the 5304. I ordered a replacement and a spare, since I have about 7 in the house. Hook up is identical to the unit being replaced. Took 30 seconds including testing. All was fine.

Replacing 5204 Smoke/Fire Alarms - 03/07/2015
Reviewer: Bruce Spesard
I replaced the 10-year old 5204 alarms in my house with the recommended 5304 alarms. Replacement was easy using the existing bracket & wiring -- twist the old unit off & unplug followed by plug the new unit in & position-&-twist onto the bracket. The 5304 was on back-order but arrived much to my delight BEFORE the promised date. I just asked the company via their website how to dispose of the old units as they contain a small amount of radioactive material and await their response.

Great product - 01/06/2015
Reviewer: Robert Pettinato
Works great and the battery backup is perfect, good for peace of mind...

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.
