Warning: The CO alarm should be installed by a qualified electrican in accordance with the IEE wiring regulations (BS 7671). Failure to install this alarm correctly may expose the user to shock or fire hazards.

Procedure:

1.Select a location complying with the above advice.

2.Disconnect the AC mains supply from the circuit to be used.

3.Slide off the cover as shown in fig 1. Press gently in the centre to release the catches before sliding upwards.

4.Remove the terminal cover screw and expose the connecting terminals.

5.(a) If the wires are coming directly out from the ceiling/wall locate the wire entry slot over the wires and mark the two mounting screw locations. Screw the unit to the ceiling/wall (ensure screws do not penetrate buried wires. The unit can also be screwed on to a standard recessed junction box if required. Seal the wire exit holes (with silicone or similar) to prevent air draughts preventing the carbon monoxide from reaching the sensor.

(b)If surface wiring is being used, bring the wiring in from either of the vertical sides or the bottom as shown in figure 5. Note surface wiring cannot be brought in from the top as it would be in the way of the cover sliding off and also might allow water to penetrate. Screw the unit to the wall.

Ei220EN specifications

The Ei Electronics Ei220EN is an advanced smoke and heat detector designed to provide enhanced safety and peace of mind in residential and commercial buildings. Incorporating state-of-the-art technologies, this device offers reliable performance and is engineered to detect both smoke and rising temperatures, ensuring comprehensive fire protection.

One of the standout features of the Ei220EN is its dual sensor technology, which combines both photoelectric and heat detection. The photoelectric sensor is adept at identifying smoldering fires that produce a significant amount of smoke, while the heat sensor excels in detecting rapid temperature increases indicative of flaming fires. This dual approach significantly reduces the potential of false alarms caused by common household activities, such as cooking or steam from showers.

The Ei220EN is equipped with a built-in 230V power supply, offering continuous operation without the need for frequent battery replacements. In the case of a power failure, a 10-year rechargeable lithium battery serves as a backup, ensuring that the detector remains operational during emergencies. This feature provides users with confidence that their premises are protected around the clock.

This smoke and heat detector also boasts a large, easy-to-read LED indicator, which shows the status of the device. During normal operation, the indicator glows green, while it turns red in the event of an alarm. Additionally, a test button allows users to easily check the functionality of the device, ensuring that it is in working order.

Another notable characteristic is the Ei220EN's ability to interconnect with up to 12 other Ei alarms, enhancing safety throughout large homes or commercial spaces. In the event of an alarm, all interconnected units will sound, creating a robust alert system that increases the chances of early detection and response to a fire.

The Ei220EN also features a low-profile design that allows for easy installation on walls or ceilings, blending seamlessly with various architectural styles. Constructed from durable materials, it is built to withstand various environmental conditions, making it suitable for different settings, whether residential or commercial.

Overall, the Ei Electronics Ei220EN smoke and heat detector is a vital component in any fire safety strategy. With its advanced dual sensor technology, reliable power source, user-friendly features, and interconnectivity options, it delivers dependable and effective protection against the dangers of fire, ensuring the safety of all occupants.
