5.TESTING YOUR CO ALARM

(1)Regularly check that the green mains power light is on. The unit cannot detect CO if the mains power is not on and the rechargeable battery is depleted. (If it is off check circuit breakers, fuses, wiring etc).

(2)Test the unit weekly by pressing the test/hush button. Hold the test button (for up to 10 seconds) until the horn sounds for over 5 seconds. This will help to familiarise you and your family with the distinctive on-off sound of the CO Alarm. This test checks that the electronics and horn are working correctly. If the units are interconnected, button test each unit in turn and check all interconnected units alarm. (If the red alarm light flashes when the button is pressed (see CO Alarm Memory section 2.3 above).

(3)If the CO Alarm gives a short beep and the amber fault light flashes every 40 seconds it means the self-checking circuit has detected a fault. Press and hold the test/hush button. If the amber light flashes without the horn sounding, the sensor is faulty. On the Ei 261DEN the display will show SF indicating Sensor Faulty.

(4)If the Alarm fails to operate when the test/hush button is pressed, disconnect the mains supply at the distribution fuse board, remove unit from mounting plate for 3 minutes. Put unit back on mounting plate. Re-connect the mains and try again. (This procedure resets the microprocessor in the unit).

(5)If the unit beeps every 40 seconds (without a light flash) it means the battery is depleted. (On the Ei 261DEN with depleted cells, the display will show CP to remind you to Connect mains Power). Connect mains (ensure green light is on) to allow cells to charge.

(6)Once a year check the rechargeable cells by switching off mains and pressing the test button for 10 seconds. The horn should sound loudly. Re-connect mains power.

If the CO Alarm fails any of the above tests it must be replaced immediately (see section 10 “Getting the CO Alarm Serviced”).

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.
