IMPORTANT NOTICE

DUST & INSECT CONTAMINATION

All Smoke Alarms and particularly the optical (photoe- lectric) type are prone to dust and insect ingress which can cause false alarms.

The latest design, materials and manufacturing tech- niques have been used in the construction of our Alarms to minimize the effects of contamination. However it is impossible to completely eliminate the effect of dust and insect contamination, and therefore, to prolong the life of the Smoke Alarm you must ensure that it is kept clean so that excess dust does not build up. Any insects or cobwebs in the vicinity of the Smoke Alarm should be promptly removed.

In certain circumstances even with regular cleaning, contamination can build up in the smoke sensing cham- ber causing the alarm to sound. If this happens the alarm must be returned to us for servicing or replace- ment. Contamination is beyond our control, it is totally unpredictable and is considered normal wear and tear. For this reason, contamination is not covered by the guarantee and a charge is made for all servicing work.

If you experience persistent false alarms, in particular locations, due to contamination of the smoke chamber you could consider fitting our ionisation type Smoke Alarm. The principle of ionisation detection makes it less vulnerable to the effects of dust or insect contamination.

WARNING

DO NOT INSTALL THE ACTU AL SMOKE ALARM IN NEW OR RENO- VATED BUILDINGS UNTIL ALL WORK IS COMPLETED (INCLUDING FLOOR COVERINGS) AND BUILDING HAS BEEN FULLY CLEANED.

(Excessive dust & debris from building work can contaminate the smoke chamber and cause problems).

An installed smoke alarm must be removed or cov- ered fully (with a plastic bag or similar) before reno- vations begin.

EI105C specifications

The Ei Electronics EI105C is a compact, highly efficient, and innovative smoke alarm designed to provide optimal safety in residential and commercial spaces. Manufactured with advanced technology, the EI105C boasts several features that enhance its performance and user experience, ensuring reliable smoke detection and giving peace of mind to users.

One of the standout features of the EI105C is its built-in 10-year lithium battery. This power source eliminates the need for regular battery replacements, ensuring continuous operation for a decade. This long-life battery is particularly appealing as it reduces maintenance efforts and allows for hassle-free installation. The unit is also equipped with a low battery warning signal, which alerts users when the battery needs to be replaced at the end of its operational lifespan.

A key characteristic of the EI105C is its optical smoke sensing technology. This technology utilizes a light source and a photodetector to detect smoke particles effectively. The optical sensor is more sensitive to smoldering fires, which often produce larger smoke particles compared to flaming fires, making it ideal for residential use where slow-burning fires are a concern. Furthermore, the EI105C is designed to minimize false alarms caused by everyday cooking activities, making it suitable for use in kitchens and other common living areas.

The EI105C also features a test and hush button that allows users to easily check the unit's functionality and silence alarms during non-emergency situations. This user-friendly design promotes regular testing and ensures that the smoke alarm remains in optimal working condition.

In terms of installation, the EI105C is straightforward and can be mounted on ceilings or walls. It is designed to be compatible with Ei Electronics' range of accessories, making it easy to integrate into existing systems. Additionally, the unit complies with stringent safety standards, ensuring that users can rely on its performance when it matters most.

In conclusion, the Ei Electronics EI105C smoke alarm combines advanced optical sensing technology and a long-lasting battery with user-friendly features to provide dependable smoke detection. Its ability to minimize false alarms while efficiently detecting smoldering fires makes it an excellent choice for both home and commercial environments, prioritizing safety and convenience.
