Product Description

Operation

The Ei105R is an Optical Smoke Alarm that that is designed to operate with suitable 12 volt control panels and to provide a loud local alarm.

Optical smoke alarms use the light scatter principle to detect smoke particles entering the optical chamber within the alarm.

Optical sensing technology gives a rapid response to visible smouldering fires.

The Ei105R is easily installed and comes supplied with all necessary screw fixings.

Relay contacts (normally open and closed supplied) are available for triggering the panel itself and its associated ancillary products, such as extra loud sirens, magnetic door holders, etc.

The alarms can be interconnected so that when one alarm senses fire, all the units located throughout the premises sound.

The smoke detector will activate the built in sounder upon sensing smoke particles

The smoke detector will automatically reset itself and silence the sounder when smoke particles are no longer present in the sensing chamber

The built in sounder will provide a minimum sound output of 85dB at 3m

In “Test” button will perform a self test and sound the horn (it may take up to 10 seconds)

Interconnect up to 12 other alarms (9V ionisation, optical or heat) when one senses smoke, all alarm. Helps ensure warning will be heard throughout the house

Ei105R specifications

The Ei Electronics Ei105R is a high-quality smoke detector designed to provide reliable protection against smoke and fire for residential and commercial applications. With its advanced features and technologies, the Ei105R stands out in the market for safety equipment, giving users peace of mind in the event of an emergency.

One of the key features of the Ei105R is its use of optical sensing technology. This type of sensor is particularly effective at detecting slow-burning fires and smoldering materials, which are common in household fires. The optical sensor operates by using a light beam that enters a sensing chamber. When smoke particles enter this chamber, they scatter the light, triggering the alarm. This technology minimizes false alarms, making it suitable for use in areas where cooking fumes or steam might otherwise cause unnecessary disruptions.

Another significant characteristic of the Ei105R is its battery backup system. It operates on a 9V battery, ensuring continuous functionality even during power outages. This feature is critical for maintaining safety at all times, especially in areas where electrical supply fluctuations are common.

The Ei105R is also designed for ease of installation and maintenance. The unit comes with a user-friendly mounting bracket, allowing for quick and hassle-free setup. Furthermore, it incorporates a test button that lets users easily check the detector's operational status. Regular testing is essential to ensure the detector is functioning properly and ready to respond to any potential hazards.

In addition, the Ei105R features a loud alarm that emits a sound level of 85 decibels. This high sound output is designed to alert occupants effectively, even in noisy environments. The unit also includes a visual indicator, providing a clear signal when the alarm is activated, as well as an end-of-life warning that notifies users when it is time to replace the unit.

Overall, the Ei Electronics Ei105R combines innovative technology with user-friendly design, making it a top choice for smoke detection. Its optical sensing technology, battery backup, easy installation, and reliable alarm system ensure that it can effectively protect lives and property from the threat of fire. Investing in the Ei105R means investing in safety and security, giving individuals and families the reassurance they need in today’s world.
