Testing with Carbon Monoxide

The unit checks for CO every 4 seconds and as soon as it detects CO it flashes the red light (as per Table

B)to confirm that is detecting CO gas. Alternatively:

Pressing the test button causes the unit to check for CO - this is the Fast CO Test Mode. This eliminates the long wait normally required e.g. up to 90 minutes at 55ppm CO and up to 3 minutes at 330ppm CO.

The unit can be tested with CO by using one of the kits that comes with CO either in a glass phial or aerosol can. Follow the instructions on the kit but be sure to press the test button to speed up the CO sampling directly after you expose the unit to the CO. It is best if possible to inject the CO gas into the gas entry holes, see Figure 1. When it senses the CO it will give 3 beeps and the red light will flash as per table B. It then resets to normal mode. (If unit fails to respond press test button again as gas can take some seconds to enter sensor).

The Fast CO Test Mode normally does not activate the memory function unless a high level of CO remains in the sensor for a few minutes. (This can be checked by pressing the test button. If the red light flashes continuously indicating CO was detected, hold the test button for 20 seconds until the red light stops flashing as the memory resets).

How to distinguish between CO Alarm and Smoke Alarm Warnings

The CO Alarm has a distinctive on-off sound of 3 pulses, followed by a pause as compared with a typi- cal Smoke Alarm which has a rapid pulsing sound.

In addition, when your CO Alarm is sounding, the red alarm light in the centre of the cover will be flashing.

Testing both your CO Alarms and Smoke Alarms weekly will help you and your family to clearly distinguish between them in an emergency.

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.
