Ei Electronics Ei650RF Optical Wireless Smoke Detector with 10-Year Lithium Battery and Interconnection Support in White

The Ei Electronics Ei650RF Optical Wireless Smoke Detector with 10-Year Lithium Battery and Interconnection Support in White is an advanced fire safety device designed to protect residential and commercial interiors. Utilizing high-performance optical sensor technology, this detector quickly identifies slow-smoldering fires by sensing low-energy smoke particles. Its wireless interconnection capability allows up to 12 compatible devices to link together, ensuring that an alert triggered in one room sounds throughout the entire building. Powered by a built-in sealed 10-year lithium battery, the device operates continuously without requiring frequent battery replacements. The clean white design blends seamlessly into standard ceiling and wall surfaces while providing dependable, low-maintenance safety.

Advantages

The Ei Electronics Ei650RF optical smoke detector offers reliable fire detection through its proprietary photoelectric sensor and protected optical chamber, which minimizes false alarms caused by dust or insects. The wireless interconnect feature eliminates the need for complex wiring, allowing seamless communication across multiple units in a property. Maintenance is straightforward thanks to the 10-year sealed lithium battery that powers the unit for its entire operational lifespan under normal conditions. Additionally, the twist-on mounting base activates the device automatically upon installation, preventing power drain during storage and ensuring a secure setup on ceilings or walls.

Suitable for

• Residential bedrooms and children’s rooms due to the lack of blinking standby lights
• Living rooms, hallways, and stairwells in houses and apartments
• Interconnected multi-room fire safety systems using wireless technology
• Commercial properties requiring scalable optical smoke detection

When it may not be suitable

This optical smoke detector is not designed for outdoor installation or environments exposed to extreme temperatures and high humidity. It may also generate false alarms if placed directly in kitchens or areas with heavy cooking vapors and steam without proper ventilation.

Key specifications

• Detector type: Optical photoelectric sensor
• Connectivity technology: Wireless interconnection
• Power source: Built-in 10-year sealed lithium battery (3V)
• Product colour: White
• Dimensions: Diameter 11.5 cm, Height 45 mm

How to use

To install the smoke detector, attach the twist-on mounting base securely to a ceiling or wall using the provided fixing points. Twisting the unit onto the base activates the internal power supply automatically. Regular testing is performed using the large integrated Test and Hush button on the front cover. Pressing this button initiates a progressive alarm sound for comfortable hearing checks and can temporarily silence nuisance alarms caused by cooking fumes for a 10-minute period. The device performs automatic self-checks every 40 seconds to monitor sensor functionality, internal circuitry, and battery status, alerting users via visual LED indicators and audio beeps if a fault occurs.

What to consider before purchase

• Verify that the wireless frequency and compatibility align with any existing Ei Electronics devices you plan to interconnect
• Ensure the intended installation location is suitable for an optical smoke detector rather than a heat or multi-sensor alarm
• Check local fire safety regulations regarding the required number and placement of interconnected smoke alarms

Usage recommendations: Test the smoke alarm regularly using the test button to ensure proper functionality. Keep the surrounding area clean and free from heavy dust or insect accumulation to maintain optimal optical sensor performance.
