If the alarm fails to sound, follow this checklist:

¥Check the age of the unit - see the replace by label on base of unit.

¥Check the battery snaps are firmly connected on the Ei405 & Ei405C models (see fig 1b).

¥On the Ei405TY & Ei405TYC models ensure the unit is pushed fully home on the mounting plate, as this connects the battery.

¥Check for any sign of contamination such as cobwebs or dust and clean the alarm as described on page 12 if nec- essary.

WARNING: Do not test with flame.

This can set fire to the alarm and damage the house. We do not recommend testing with smoke as the results can be mis- leading unless special apparatus is used.

6.2Checking the Wireless Interconnect

We recommend that the interconnect is tested weekly as follows:

1.Press and hold the test button on the first alarm for 5 sec- onds (count up to 10).

2.The horn will sound and then the blue light will come on continuously for 3.5 seconds. (This indicates that the unit is transmitting a Radio Alarm signal to the other units). Release the test button. The local alarm will cease and you should then be able to hear the other alarms sounding in the dis- tance.

3.Repeat this procedure for all the other alarms.

If any units appear not to operate remove models (Ei405 & Ei405C only) from the mounting plate (as shown in figure 1a) and ensure battery is firmly connected to the snaps. If the wireless link does not appear to operate ensure you have held the test button down until the blue light has come on continu- ously (this could take up to 5 seconds).

(If there still appears to be a problem with the wireless link it may be necessary to resite/rotate some units - see section below on "House Coding your Units").

We strongly recommend that you house code your units so that your system will not be triggered by similar systems in the neighbourhood.

6.3House Coding your Units

The units can transmit and receive over 150 metres minimum (in free space) so it is important to ensure neighbouring sys- tems do not interfere with your system. The following proce- dure programs the units so each learns the serial numbers of all the other units on the system. After they have been pro- grammed they will only communicate with units programmed at the same time (that were within range).

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.
