INSTALLATION PROCEDURE

(1)Select a location complying with the above advice.

(2)Disconnect the AC mains supply from the circuit that is going to be used.

(3)The house wiring must be connected to the terminal block on the mounting plate as follows:

L:Live - connect to the house wires coloured brown or marked L.

N:Neutral - connect to the house wires coloured blue or marked N.

IC: Interconnect - If you are only installing one alarm do not connect any cable to the IC terminal. See below for information on interconnecting.

Warning: Mixing Live & Neutral wires will damage interconnected alarms.

Do not use an earth wire for the interconnect line. Use a suitably coloured core, with the ends marked if necessary, for the interconnect that will not be confused with the live or neurtal cores.

(4) Lift off the wiring cover as shown in Figure 5.

N.B. The Alarm does not need to be earthed. However the terminal marked is provided for the con- venience of the installer so that any copper earth wire or cable coloured green or green & yellow, can be safely terminated.

(5)If the mains wires are being brought along the surface, conduit can be inserted into the top and/or bottom, for the cable.

(a)position the mounting plate, so that the cable conduit is as shown in Figure 5.

(b)Carefully cut around the knockout on the outside wall so the conduit fits. (Note: to comply with the BS EN 60529, IPX2D protection rating, seal around conduit with silicone rubber or similar to prevent water entering).

(6) If the mains wires are recessed, bring the wires through the rear hole in the mounting plate as shown

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.
