4. Setup and Installation
4.1 Choosing a Location
For optimal protection, install smoke detectors in every sleeping area and on every level of your home, including the basement. Avoid installing in:
- Kitchens, garages, or furnace rooms where cooking fumes or exhaust can cause nuisance alarms.
- Near air vents, fans, or windows that can interfere with smoke reaching the detector.
- Within 20 feet of a cooking appliance.
- In extremely dusty, dirty, or insect-infested areas.
4.2 Battery Installation/Activation
The 5806W3 uses one 3V CR123A Lithium battery. If the battery is not pre-installed or needs replacement:
- Remove the detector from its mounting bracket by twisting counter-clockwise.
- Open the battery compartment cover.
- Insert the CR123A battery, observing the correct polarity (+/-).
- Close the battery compartment cover.
- The detector will chirp briefly and the LED will flash to indicate power-up.
4.3 Mounting the Detector
- Position the mounting bracket on the ceiling or wall at your chosen location.
- Mark the screw hole locations.
- Drill pilot holes if necessary and insert wall anchors.
- Secure the mounting bracket with the provided screws.
- Align the detector with the mounting bracket and twist clockwise until it locks securely into place.
4.4 Enrolling with the Security System
The 5806W3 is a wireless device and must be enrolled into a compatible Honeywell security system. Refer to your security system's installation manual for specific enrollment procedures. General steps include:
- Put your security system into programming mode.
- Select a zone for the smoke detector.
- Activate the smoke detector's tamper switch (by removing it from the mounting plate) or press the test button to transmit its serial number to the control panel.
- Confirm the enrollment on the control panel.
- Exit programming mode.
Note: The 5806W3 typically uses a loop number for smoke detection and a separate loop for low battery/supervision. Consult your system's manual for correct loop programming.
5. Operation
5.1 Normal Operation
Under normal conditions, the detector's LED will flash approximately once every 10-12 seconds, indicating proper operation and communication with the control panel.
5.2 Testing the Detector
Test the smoke detector weekly and after any battery replacement or system maintenance.
- Press and hold the test button located on the detector's cover for at least 3 seconds.
- The detector should emit a loud, pulsating alarm sound.
- The LED will flash rapidly.
- The alarm signal should be transmitted to the control panel.
- Release the test button. The alarm will cease.
Note: If the detector does not alarm during testing, refer to the Troubleshooting section.
5.3 Alarm Conditions
When smoke is detected:
- The detector will emit a loud, continuous temporal 3 pattern alarm (three long beeps followed by a pause).
- The LED will flash rapidly.
- An alarm signal will be sent to the security control panel, which will then activate its siren and transmit a signal to the central monitoring station (if applicable).
IMPORTANT: If an alarm sounds, evacuate all occupants immediately and call the fire department from a safe location.
6. Maintenance
6.1 Battery Replacement
When the battery is low, the detector will chirp approximately once every 48 seconds, and a low battery signal will be sent to the control panel. Replace the battery immediately.
- Twist the detector counter-clockwise to remove it from the mounting bracket.
- Open the battery compartment.
- Remove the old CR123A Lithium battery.
- Insert a new 3V CR123A Lithium battery, observing correct polarity.
- Close the battery compartment.
- Re-attach the detector to the mounting bracket by twisting clockwise.
- Test the detector after battery replacement (refer to Section 5.2).
Note: Dispose of used batteries according to local regulations.
6.2 Cleaning the Detector
Clean the smoke detector at least once a year to remove dust and debris that could interfere with its operation.
- Remove the detector from its mounting bracket.
- Gently vacuum the exterior of the detector, especially around the sensing chamber openings, using a soft brush attachment.
- Do not use cleaning solvents or spray chemicals directly on the detector.
- Re-attach the detector to the mounting bracket.
- Test the detector after cleaning (refer to Section 5.2).
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not alarm during test. | Dead or low battery; Faulty unit. | Replace battery. If problem persists, contact technical support. |
| Detector chirps every 48 seconds. | Low battery. | Replace battery immediately. |
| Nuisance alarms (false alarms). | Improper location (near cooking, high humidity); Dust/debris in sensing chamber. | Relocate detector. Clean detector (refer to Section 6.2). |
| Detector not communicating with control panel. | Not properly enrolled; Out of range; Interference. | Re-enroll detector. Check signal strength. Relocate detector or control panel. |
