(Without this feature the CO level would need to be at 50ppm CO for 90 minutes for an indication to be given). Note the Pre-Alarm signal may be triggered by CO coming for example, from cooking with gas, from car engines or from nearby barbecues. This is usually not a concern unless the Pre-Alarm signal persists until the alarm sounds and the CO source is unknown.

NOTE: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols are released nearby.

CO ALARM MEMORY

-Red light is Off – No CO detected since reset or power up.

-Red light flashes 2 times (in 2 seconds) every 40 seconds, 50 ppm CO detected for least about 90 minutes.

-Red light flashes 4 times (in 2 seconds) every 40 seconds, 100 ppm CO detected for least about 40 minutes.

-Red light flashes 8 times (in 2 seconds) every 40 seconds, 300 ppm CO detected for at least about 3 minutes.

When the test button is pressed the horn will sound, and the red light will only flash if the unit has previously detected CO and been in alarm. The flash rate indicates the level of CO detected as in table B.

Reset Memory by holding down the test button for over 20 seconds until the red light stops flashing. Cover the horn with a cloth to muffle the alarm during this time.

Please note that the memory will also be reset when the unit is unpowered.

Ei220EN specifications

The Ei Electronics Ei220EN is an advanced smoke and heat detector designed to provide enhanced safety and peace of mind in residential and commercial buildings. Incorporating state-of-the-art technologies, this device offers reliable performance and is engineered to detect both smoke and rising temperatures, ensuring comprehensive fire protection.

One of the standout features of the Ei220EN is its dual sensor technology, which combines both photoelectric and heat detection. The photoelectric sensor is adept at identifying smoldering fires that produce a significant amount of smoke, while the heat sensor excels in detecting rapid temperature increases indicative of flaming fires. This dual approach significantly reduces the potential of false alarms caused by common household activities, such as cooking or steam from showers.

The Ei220EN is equipped with a built-in 230V power supply, offering continuous operation without the need for frequent battery replacements. In the case of a power failure, a 10-year rechargeable lithium battery serves as a backup, ensuring that the detector remains operational during emergencies. This feature provides users with confidence that their premises are protected around the clock.

This smoke and heat detector also boasts a large, easy-to-read LED indicator, which shows the status of the device. During normal operation, the indicator glows green, while it turns red in the event of an alarm. Additionally, a test button allows users to easily check the functionality of the device, ensuring that it is in working order.

Another notable characteristic is the Ei220EN's ability to interconnect with up to 12 other Ei alarms, enhancing safety throughout large homes or commercial spaces. In the event of an alarm, all interconnected units will sound, creating a robust alert system that increases the chances of early detection and response to a fire.

The Ei220EN also features a low-profile design that allows for easy installation on walls or ceilings, blending seamlessly with various architectural styles. Constructed from durable materials, it is built to withstand various environmental conditions, making it suitable for different settings, whether residential or commercial.

Overall, the Ei Electronics Ei220EN smoke and heat detector is a vital component in any fire safety strategy. With its advanced dual sensor technology, reliable power source, user-friendly features, and interconnectivity options, it delivers dependable and effective protection against the dangers of fire, ensuring the safety of all occupants.
