Carefully line up the unit on the base and slide on.

Press the test/hush button for 10 seconds. The horn will sound.

CAUTION: Do not attempt to remove the Alarm without first releasing the tamper clip as shown in Figure 1.

(8)Connect the mains power to the alarm circuit. Check the green light is on.

The CO Alarm is now fully operational and will provide protection against a build up of Carbon Monoxide gas, 70 seconds after it is connected to the mains supply.

(9)The unit may be tamperproofed further, by removing the knockout in the sidewall of the mounting plate as shown in Figure 1. Insert the self tapping screw (3mm diameter, 12mm long) after the unit is on the mounting plate.

INTERCONNECTING Ei ELECTRONICS CARBON MONOXIDE ALARMS

With interconnected alarms, when one unit detects CO all units alarm. All horns will sound but only units detecting CO will flash their red lights.

A maximum of twelve Ei 261EN/261DEN CO Alarms may be interconnected along with an Ei 128C module with relay (see technical specifications).

WARNING: Do not connect these Alarms to any other type of Ei Alarm, or to any other model produced by another manufacturer, apart from those listed above. Doing this may damage the Alarms and could result in a shock or fire hazard.

The interconnect wire (minimum 0.75mm2 cable) must be treated as if it was live. It should be insulated and sheathed.

A maximum of 250 metres (820 ft) of wire can be used (maximum resistance between detectors 50

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.
