After 5 years operation, the amber light will flash once every 40 seconds (without a beep) to indicate the sensor should be replaced. (Note: cover the ‘replace sensor’ label on side of unit with the new ‘replace unit’ by label supplied with the new sensor).

It must also be replaced if the amber light flashes and the unit beeps every 40 seconds as this indicates the sensor is faulty.

Remove the alarm from the mounting plate as described above. Pull out the sensor module from the rear. Replace with a new sensor module (Model No. Ei 261MEN) (Contact Aico or Ei Electronics, for your near- est module supplier). Carefully align the module including the connector pins and push firmly home. Slide the alarm back on to the mounting plate. Reconnect the mains supply. Wait 4 minutes for the new sensor to stabilise and then press the test button - the horn should sound.

Check the alarm as described in section 4 above.

Note: When the second sensor has completed its 5 years of operation the amber light will flash every 40 seconds. The sensor module can only be replaced once. The entire unit must be replaced after 10 years. The date for replacing the entire unit is given on the base.

7.LIMITATIONS OF CO ALARMS

(1)The Ei 261EN/261DEN CO Alarm will not work without mains power if the rechargeable cells are depleted. The green power light must be on at all times as far as possible.

(2)Carbon Monoxide must enter the unit for it to be detected. There may be Carbon Monoxide in other areas of the house (e.g. downstairs, in a closed room etc). but not in the vicinity of the CO Alarm. Doors, air draughts and obstructions can prevent the CO reaching the Alarm. For these reasons we recommend

Ei 261DEN, Ei 261EN specifications

Ei Electronics is renowned for its innovation in the fire detection and alarm industry, and among its impressive product offerings, the Ei 261DEN and Ei 261EN smoke alarms stand out for their reliability and advanced features. Both models are designed to provide maximum safety and ease of use in residential and commercial settings.

The Ei 261DEN is equipped with a high-performance optical smoke sensor that detects a broad range of smoke particles, making it particularly effective at sensing smoldering fires. Its intelligent design allows it to differentiate between genuine fire situations and false alarms, such as from cooking smoke or steam. This capability reduces nuisance alarms, ensuring that users remain alert but not overly disturbed by non-threatening activations.

On the other hand, the Ei 261EN offers a similar level of performance with slight variations in features tailored to different environments. This model also utilizes a reliable optical smoke sensor but includes enhanced connectivity options for integration with other alarm systems. The Ei 261EN is particularly suited for larger homes or commercial spaces where multiple interconnected alarms can provide a comprehensive safety network.

One of the prominent characteristics of both models is their user-friendly interface. Each alarm is designed with an easy-to-use test button that allows users to check the functionality of the unit quickly. Additionally, these devices feature a low battery warning system that alerts users when it’s time to replace the battery, ensuring that the alarm remains operational at all times.

Another critical feature is the sealed battery technology found in these alarms. The Ei 261DEN and Ei 261EN come with long-lasting batteries that can power the alarm for up to ten years, eliminating the need for frequent battery changes. This design enhances user convenience and ensures uninterrupted protection.

In terms of build quality, both models are constructed to withstand harsh conditions, making them suitable for various installations. Their compact design and modern aesthetics ensure they can blend seamlessly into any environment without compromising on functionality.

In summary, the Ei Electronics Ei 261DEN and Ei 261EN smoke alarms embody advanced fire detection technology, user-centric design, and robust performance. Their features make them ideal for ensuring safety in both homes and workplaces, highlighting Ei Electronics' commitment to innovation and reliability in safety solutions.
