Mark the position of the two mounting holes by using the unit as a template. Drill two holes using a 6mm drill for the plastic plugs supplied, (ensure you don’t drill into the house wiring). Screw the unit to the wall.

Check that the CO Alarm can be heard in all the bedrooms. If not another CO Alarm should be located nearer the bedrooms.

5.2HOW TO TAMPERPROOF THE ALARM

The battery compartment can be made tamperproof by using the white locking rivet supplied with the screw pack as follows:

(i)Remove the battery cover as shown in figure 5a.

(ii)Remove the post shown in figure 6. Place it on the corner of a table and push downwards (note: cover unit with a cloth to prevent the post flying upwards). This should leave a neat circular hole.

(iii)Put the battery cover back on the unit. Insert the white locking rivet into the hole and push fully home. See figure 7.

The battery compartment cannot now be opened unless the rivet is removed first. This can be removed by inserting a thin screwdriver or blade under the edge and levering it up.

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.
