4.3On a sloping Ceiling

In areas with sloping or peaked ceilings install your Smoke Alarm 0.9m from the highest point measured horizontally (see figure 6), because dead air at the apex may prevent smoke from reaching the unit.

4.4Locations to Avoid

Don t place your Smoke Alarm in any of the following areas:

¥Bathrooms, kitchen, shower rooms, garages or other rooms where the smoke alarm may be triggered by steam, condensation, normal smoke or fumes.

¥Attics or other places where extremes of temperature may occur (below 4¡C or above 40¡C).

¥Near a decorative object, door, light fitting, window molding etc., that may prevent smoke from entering the Smoke Alarm.

¥Surfaces that are normally warmer or colder than the rest of the room (for example attic hatches, uninsulated exteri- or walls etc). Temperature differences might stop smoke from reaching the unit.

¥Next to or directly above heaters or air conditioning vents, windows, wall vents etc. that can change the direction of airflow.

¥In very high or awkward areas where it may be difficult to reach the alarm for testing.

¥Locate unit at least 1.5m away from fluorescent light fit- tings as electricial noise and/or flickering may affect the unit.

¥Locate away from very dusty or dirty areas as dust build- up in the chamber can make unit too sensitive and prone to alarm. It can also block the insect screen mesh and pre- vent smoke from entering the chamber.

¥Do not locate in insect infested areas. Small insects get- ting in to the chamber can cause intermittent alarms.

4.5Nuisance/False Alarms

If, when the alarm goes off, there is no sign of smoke, heat or noise to indicate that there is a fire, you should get your fam- ily into a safe place, before you start investigating.

Check the house carefully in case there is a small fire smoul- dering somewhere.

Check whether there is some source of smoke or fumes, for example cooking fumes being drawn past the Smoke Alarm by an extractor.

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.
