Smoke detector ei electronics Ei650iC with 10-year lithium battery, model EI650IC

The ei electronics Ei650iC is a mains-independent smoke detector with an integrated 10-year lithium battery, designed to deliver long-term, low-maintenance smoke detection for homes and small premises. The device uses photoelectric sensing to identify visible combustion particles and is intended for ceiling mounting to provide early warning of developing fires. Its sealed battery design eliminates the need for periodic battery replacement and supports continuous operation throughout the product service life.

Advantages

The detector provides up to 10 years of power from a factory-fitted lithium cell, reducing routine maintenance and the risk of power interruption due to depleted batteries. Photoelectric detection improves response to smouldering fires and slow-burning sources of smoke. The compact, ceiling-mounted form factor and clear alarm signal ensure unobtrusive installation and reliable audible alerting. The unit is designed for long-term operation and straightforward replacement at end of service life.

Suitable for

• Private homes and apartments
• Bedrooms and living areas
• Small offices and non-industrial premises
• Hallways and common areas in multi-storey dwellings

Key specifications

• Type of sensor: photoelectric smoke sensor
• Power source: built-in 10-year sealed lithium battery
• Mounting: ceiling installation
• Alarm output: audible alarm at specified dB level for residential detectors
• Service life: designed for continuous operation for up to 10 years
• Environmental operation range: suitable for normal indoor temperatures and humidity

How to use

Install the detector on a ceiling in a central position of the protected room, away from air vents, windows and doors to avoid false alarms caused by drafts. Follow the mounting template and fixings supplied by the manufacturer for secure attachment. After installation, test the alarm using the built-in test button to confirm the audible signal and that the device is operational. Do not attempt to open the sealed battery compartment; the unit is intended to operate for its rated service life without battery replacement. Replace the entire unit at the end of its service life as indicated by the manufacturer's end-of-life signal.

Usage recommendations

Position detectors on every habitable floor and inside or outside sleeping areas for optimal early warning. Avoid installing directly above cooking appliances to reduce nuisance alarms; instead, place detectors at least the recommended distance from kitchens. Regularly test the unit (for example, monthly) using the test button and keep the sensor clean from dust and paint. If the alarm activates, follow local emergency procedures and evacuate immediately.
