A maximum of 250 metres (820ft) of signal cable can be used, (maximum resistance between detectors 50 ohm). The units are interconnected by wiring all the terminals marked 1 together, and all the terminals marked 2 together (as in fig 8) before screwing the mounting plate to ceiling. Draughts, through the ceiling, from wiring openings, conduit, or mount- ing boxes/holes, may blow smoke away from the sensing chamber, making it insensitive. It is essential that all such openings including the wiring hole (see figure 9) be closed by silicone sealant or similar.

1.Remove the Smoke Alarm from the mounting plate as shown in fig 1a

2.Lift the wiring cover on the mounting plate as shown in fig 9.

3.Connect the two core cable to the terminal block as shown in fig 10.

4.Replace the wiring cover and attach the smoke alarm to the mounting plate.

Figure 10

After wiring together the Interconnect Smoke Alarms, test the first unit by pressing the button. All the detectors should alarm and the test button on the first unit will flash about once a second. Please note it can take up to 5 seconds for some of the interconnected units to sound. Check all the other units similarly.

Check the Radio Interconnect as described above.

These Smoke Alarms should be interconnected only within the confines of a single family living unit. If they are connect- ed between different units there may be excessive nuisance alarms. Everybody may not be aware that they are being test- ed or that it is a nuisance alarm caused by cooking etc.

8.IMPORTANT SAFEGUARDS

When using household protective devices, basic safety pre- cautions should always be followed, including those listed below

¥Please read all instructions.

¥Rehearse emergency escape plans so everyone at home knows what to do in case the alarm sounds.

Ei 405C, Ei 405TYC, Ei 405TY specifications

Ei Electronics has established itself as a leading brand in the field of smoke alarms and carbon monoxide detectors. Among its impressive lineup, the Ei 405TY, Ei 405TYC, and Ei 405C models stand out for their innovative design and advanced technologies, ensuring safety in residential and commercial environments.

The Ei 405TY model is a premium smoke alarm that utilizes a state-of-the-art optical sensing technology. This technology enhances the alarm's ability to detect slow-burning fires, such as those caused by smoldering materials. One of the primary features of the Ei 405TY is its high-performance photoelectric chamber, which minimizes false alarms while maximizing fire detection reliability. It is equipped with an intelligent feature that allows for a resettable alarm, providing peace of mind in everyday situations. The alarm also produces a clear, loud alert, ensuring that occupants are promptly notified in case of danger.

The Ei 405TYC model builds upon the features of the Ei 405TY but adds a significant layer of versatility with its built-in carbon monoxide detection capability. This dual-functionality allows for comprehensive protection against both smoke and carbon monoxide, a colorless and odorless gas that poses serious health risks. The Ei 405TYC incorporates advanced microcontroller technology, which ensures accurate detection and notifications for varying levels of CO concentration. Additionally, it features a visual indicator that provides information about the alarm's operational status, enhancing its user-friendliness.

The Ei 405C model is designed for those seeking a reliable and straightforward smoke detection solution. It employs the same optical sensing technology found in the Ei 405TY but without the carbon monoxide detection feature. This model excels in smaller spaces, where it serves effectively as a dedicated smoke alarm. Its easy installation and maintenance are supported by a user-friendly design, making it an ideal choice for homeowners or property managers looking for a cost-effective safety solution.

All three models are designed with long-lasting battery life, ensuring they remain functional even during power outages. Additionally, they feature a tamper-proof design to prevent accidental removal. The Ei Electronics alarms are compliant with international safety standards, emphasizing the brand's commitment to quality and reliability in personal safety. Overall, the Ei 405TY, Ei 405TYC, and Ei 405C models represent a blend of advanced technology and practical features, providing essential fire and carbon monoxide detection for peace of mind in any environment.
