1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Universal Security Instruments AMIC1510SB Combination 3-in-1 Hardwired Smoke, Fire & CO Alarm Detector. This device is designed to provide early warning of smoke, fire, and carbon monoxide (CO) presence in residential environments. Please read this manual thoroughly before installation and keep it for future reference.
2. Safety Information

3. Product Features
The AMIC1510SB detector combines three critical safety functions in one unit:
- Smoke Detection: Utilizes advanced sensing technology to detect smoke from fires.
- Fire Alarm: Provides an audible alert in case of fire.
- Carbon Monoxide (CO) Detection: Monitors for dangerous levels of carbon monoxide gas.
- Hardwired with 10-Year Permanent Power Battery Backup: Ensures continuous operation even during power outages for the life of the alarm.
- Silence Button: Allows temporary silencing of nuisance alarms.
- Test Button: For easy weekly testing of all alarm functions.

4. Setup and Installation
Before installation, ensure the power to the circuit where the alarm will be installed is turned OFF at the main fuse or circuit breaker box.
4.1 Mounting Location
- Install at least one alarm on every level of your home, including basements.
- For best protection, install a smoke alarm in every sleeping room and outside each separate sleeping area.
- For CO detection, install near sleeping areas and on every level of the home.
- Avoid installing near windows, doors, or forced-air vents where drafts could interfere with detection.
- Do not install within 6 inches of a corner or within 4 inches of a wall (for ceiling mounting).
4.2 Wiring Instructions
The AMIC1510SB is designed for hardwired installation. It typically connects to a standard 120V AC household electrical circuit. The alarm comes with three wires:
- Black Wire: Connect to the hot (live) wire of the AC circuit.
- White Wire: Connect to the neutral wire of the AC circuit.
- Yellow Wire: Used for interconnecting multiple alarms. Connect to the interconnect wire of other compatible alarms. If not interconnecting, cap this wire with a wire nut.
Secure all wire connections with approved wire nuts. After wiring, attach the alarm to the mounting bracket and restore power to the circuit. The alarm will chirp once and the green POWER LED will illuminate, indicating it is receiving AC power.
5. Operating Instructions
5.1 Indicator Lights
| Indicator | Color | Status/Meaning |
|---|---|---|
| POWER | Green | Solid: Receiving AC power. Flashing: Alarm in standby or test mode. |
| SMOKE | Red | Flashing rapidly with audible alarm: Smoke detected. |
| CO | Red | Flashing rapidly with audible alarm: Carbon Monoxide detected. |
5.2 Test Button
Press and hold the "HOLD TO TEST WEEKLY" button for a few seconds. The alarm will sound a loud, pulsating horn, and the indicator lights will flash. This confirms the alarm's electronics, horn, and battery backup are functioning correctly. Release the button to stop the test.
5.3 Silence Button
In case of a nuisance alarm (e.g., from cooking smoke), press the "PRESS TO SILENCE" button. This will temporarily silence the alarm for approximately 10 minutes. If the smoke or CO concentration persists, the alarm will reactivate.
6. Maintenance
6.1 Weekly Testing
Test your alarm weekly by pressing and holding the "HOLD TO TEST WEEKLY" button until the alarm sounds. This ensures proper operation.
6.2 Cleaning
Clean your alarm at least once a month. Use a soft brush or a vacuum cleaner with a soft brush attachment to remove dust and debris from the alarm's vents and openings. Do not use cleaning solvents or sprays directly on the alarm.
6.3 End of Life Indication
This alarm has a 10-year operational life. After 10 years from the date of manufacture, the alarm will indicate its end-of-life by chirping periodically. When this occurs, the entire unit must be replaced immediately.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm chirps periodically (e.g., every 30-60 seconds) | End of life, low battery backup, or malfunction. | If 10 years old, replace unit. If newer, ensure proper AC power. If chirping persists, replace unit. |
| Alarm sounds without apparent smoke/CO | Nuisance alarm (cooking, steam), dust, or malfunction. | Press silence button. Clean alarm. If false alarms persist, relocate or replace. |
| Alarm does not sound during test | No AC power, faulty unit. | Check circuit breaker. Ensure green POWER LED is on. If not, replace unit. |
| Alarm goes into repeating self-testing mode | Internal malfunction. | This indicates a fault. The unit must be replaced immediately. Disconnect power if necessary. |
