Testing with CO

: The red light flashes (as per Table B) within 10 seconds of

 

unit detecting CO.

Initialisation Time

: 70 seconds. On power up red and amber lights flash

 

momentarily to show they are operational.

Operating Temperature

: -10°C to 40°C

Humidity Range

: 15% to 95% R.H. (non-condensing)

Audible Alarm

: 85dB(A) at 3m minimum

Self Diagnostics

: Horn beep and amber fault light flashes every 40 seconds if a

 

sensor fault is found.

Tamperproof

: Locking Rivet(s) supplied.

Interconnect

: Up to 12, Ei205CEN Alarms can be interconnected, so

(Ei205CEN only)

that when one senses CO, all alarm.

CO Alarm Memory:

: A unit will indicate if it has been in alarm previously by

(Ei205EN

flashing the red light for 2 seconds every 40 seconds

& Ei205CEN only)

(2 flashes for 50 ppm CO, 4 flashes for 100 ppm CO and

 

8 flashes, for 300 ppm CO). When the test button is

 

pressed the red light flashes as per table B and also

 

indicates the previous CO alarm level detected. The

 

memory is cleared by holding down the test button until

 

the red light stops flashing.

Ei 204EN, Ei 205EN, Ei 205ENA, Ei 205CEN specifications

Ei Electronics has established a strong reputation in the field of home safety, particularly with its innovative range of smoke alarms and detectors. Among its flagship products are the Ei 205CEN, Ei 205EN, Ei 205ENA, and Ei 204EN models, each featuring advanced technologies designed to provide reliable and effective fire safety solutions.

The Ei 205CEN is a high-performance optical smoke alarm. Its unique design incorporates a state-of-the-art photoelectric sensing technology that enhances its ability to detect slow-burning fires, such as those caused by smoldering materials. This model features a sealed lithium battery that ensures longevity and requires minimal maintenance. Additionally, it is equipped with a test and hush button for user convenience.

The Ei 205EN model takes safety a step further, offering both smoke and carbon monoxide detection capabilities. This dual-functionality makes it an ideal choice for households concerned about the dangers posed by both smoke and toxic gases. The Ei 205EN utilizes the same photoelectric sensing technology as the Ei 205CEN, ensuring rapid response to threats. Moreover, it has an easy-to-read LED indicator that provides visual feedback on the status of the unit, enhancing user awareness.

Building on the features of the Ei 205EN, the Ei 205ENA includes an added benefit of an emergency escape light. This model provides not only smoke and carbon monoxide detection but also illumination during power outages, guiding residents to safety in critical situations. Its intelligent design ensures that the escape light activates automatically when the alarm is triggered, providing peace of mind during emergencies.

Lastly, the Ei 204EN model is designed primarily for smoke detection, utilizing an enhanced photoelectric sensor that minimizes false alarms while maintaining high sensitivity to legitimate threats. This model is particularly suited for areas where unwanted alarms can be disruptive, such as kitchens and living rooms.

Each model in the Ei Electronics lineup is engineered with user-friendly features including clear audio alerts, easy installation, and battery backup options. Collectively, these devices contribute to a comprehensive home safety system that prioritizes user protection and peace of mind. With a commitment to reliability and innovation, Ei Electronics continues to lead the way in smoke and carbon monoxide detection technology.
