Important Safety Information
WARNING: This device is a smoke detector and not a fire alarm system. It is designed to detect smoke and provide a visual alert.
All life safety devices should be tested annually according to NFPA72 standards.
Do not paint the detector. Paint may interfere with the unit's ability to detect smoke.
This detector is not suitable for use in areas with high humidity or extreme temperatures outside the specified operating range.
Setup and Installation
The System Sensor 2W-B i3 Series smoke detector features a plug-in design for easy installation.
Unboxing and Components
Upon opening the package, you will find the smoke detector unit and an instruction guide. The detector consists of two main parts: the base, which connects to the wiring, and the detector head, which twists onto the base.

Wiring and Mounting
This is a 2-wire system designed for 12/24 VDC power. Refer to the included wiring diagram in the instruction guide for specific connection details. The base plate should be securely mounted to the ceiling or wall.
Once the base is wired, align the detector head with the base and twist clockwise until it locks into place.
Note: Ensure power is disconnected before performing any wiring or installation.
Operation
Once properly installed and powered, the detector will begin normal operation.
Indicator Lights
- Green LED (Normal Operation): A blinking green light indicates that the detector is receiving power and functioning correctly. This light typically blinks approximately once every minute.
- Red LED (Alarm Condition): A solid red light indicates that the detector has sensed smoke and is in an alarm state.

Advanced Detection
The i3 Series incorporates drift compensation and smoothing algorithms to differentiate between actual smoke conditions and nuisance factors like dust or cooking fumes, reducing false alarms.
Maintenance
Regular maintenance is crucial for ensuring the continued reliability of your smoke detector.
Cleaning
The detector's cover and chamber are removable for easy cleaning. Gently vacuum or use a soft, damp cloth to remove dust and debris from the exterior and interior chamber. Do not use cleaning solvents.
Testing
Test the detector monthly by pressing the test button or using approved smoke detector test spray. The red LED should illuminate, and the alarm should sound. If the alarm does not sound, replace the detector immediately.
Annual professional testing according to NFPA72 is recommended.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Green LED | No power or wiring issue. | Check power supply and wiring connections. Consult a qualified electrician if necessary. |
| Frequent Nuisance Alarms | Detector location, dust accumulation, or environmental factors. | Clean the detector chamber. Relocate the detector away from cooking fumes, high humidity, or dusty areas. |
| Red LED On, No Smoke | Detector fault or sensitivity issue. | Clean the detector. If the issue persists, the detector may need replacement. |
| Alarm Does Not Sound During Test | Detector malfunction. | Replace the detector immediately. |
