USI Electric Product Overview

Fire. Carbon monoxide. Natural gas leaks. These harmful substances can cause death or injury in the home. But how do you mitigate the risk for these hazards? You can prevent disaster through detection by investing in products that provide early warnings and peace of mind.

USI offers different detectors to alert you when carbon monoxide, fires, or natural gases pose a threat to your safety. We’ll share some common USI detector models and their features.

USI 1204HA

The USI 1204HA smoke detector and fire alarm model hardwires to 120V power and includes a backup battery. Connect it with up to 18 other alarms for added safety throughout your home. The 1204HA also has an originating alarm feature in which the initial detector’s red LED flashes to determine where the fire started.

To update from older USI smoke detectors, the USI 1204HA model directly replaces the 1204A, 1208, 1209, 1213, and the SS-790 smoke alarm models.

When replacing USI smoke detectors manufactured before 2016, remove and entirely replace the old mounting bracket with the new unit’s provided bracket. The 1204HA mounting plate measures 5 5/8 inches.

USI 5304

The USI 5304 smoke detector and fire alarm features tamper proofing with a sealed cover that cannot be removed. Pull the installed locking pins using long nose pliers to remove the USI smoke detector from the mount to clean the detector or replace the battery.

The USI 5304 model directly replaces obsolete models 5204 and SS-2795.

When replacing USI smoke detectors manufactured before 2016, remove and entirely replace the old mounting bracket with the new unit’s provided bracket.

USI MCN108

Use a carbon monoxide and natural gas detector to catch the buildup of dangerous gases before it’s too late. Excess carbon monoxide causes poisoning and death, and natural gas buildup can cause explosions.

Place a USI MCN108 detector in your home to help reduce the risk of these accidents.

The USI MCN108 detector hardwires to 120V with a 9V battery backup. It also features tamper resistance preventing alarm and battery removal.

Use the USI-MCN108 model to directly replace the USI-7390.

The carbon monoxide and natural gas detector’s end-of-service warning, 2 chirps approximately every 20 seconds, will signal about 7 years after starting up.

USI MIC1509S

For a combo smoke detector capable of sensing smoke, fire, carbon monoxide, and natural gas, consider the MIC1509S combination alarm model. It offers nuisance alarm resistance with its microprocessor intelligence.

The combo smoke detector also features a sealed 10-year battery, so you don’t have to worry about changing batteries. And around 10 years after activation, the MIC1509S will give end-of-service warning, 2 chirps about every 60 seconds, to let you know to replace it.

Directly replace the USI-7795 and MICN109 models with a MIC1509S.
