¥If the Alarm beeps without the red light flashing at the same time then clean unit as this is the automatic test fea- ture indicating the chamber is degraded.

¥Plan your escape route.

¥Proper protection usually requires more than one Smoke Alarm.

¥If you have any doubt or query about Smoke Alarms con- sult the supplier or your local Fire Brigade.

¥Models Ei405TY & Ei405TYC - When the Alarm beeps and the red light flashes at the same time or the blue light flashes every 9 seconds it indicates the battery is depleted and the entire alarm must be replaced. This normally occurs after 10 years has elapsed.

¥Models Ei405 & Ei405C - When the Alarm beeps and the red light flashes at the same time replace the battery (see fig 1).

The wireless interconnect will operate as received once the batteries are connected. (Program units if nearby systems are like-

ly to cause false alarms).

2. INTRODUCTION

Congratulations on purchasing Ei405 Radio Smoke Alarms. You can easily install these alarms throughout the house in closed rooms, corridors and in the attic for the fastest response to developing fires.

Closed doors are great for slowing down the spread of fire, but unfortunately they can also greatly slow down the response time of alarms, as they block the smoke getting to them. Without interconnection, closed doors also greatly reduce the alarm sound level throughout the house, so even though the fire is detected early, the alarm may not be heard.

The Ei405 Radio Smoke Alarms offer the comfort of intercon- nection without the hassle of installing the interconnect wires. The wireless interconnect helps ensure the alarm will be heard everywhere - including most importantly, the bedrooms.

The wireless interconnect will operate as received once the batteries are connected. To check operation, first connect all the batteries (see section 1) and then hold down the test but- ton on the first unit until the blue light comes on continuously for 3.5 seconds. All the other smoke alarms will respond with- in 5 seconds. If there is any possibility of a neighbour having a similar system, you should program your units so your sys- tem will not cause his/hers to alarm or vice versa. This is eas- ily done and only takes a few minutes- see below (section 6.3).

A remote control Ei410 is available to allow you to test and hush the alarms, without having to reach up to the smoke alarms on high ceilings. The remote control also has a "Locate" button to identify the unit causing the alarm - this is

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.
