4.2 Interconnecting Alarms

Note: A maximum of twelve Ei141/144/146/161RC /164RC/166RC Smoke or Heat Alarms may be interconnected along with an Ei128R pattress with relay (see “ACCESSORIES” section on page 15).

If you wish to connect more than twelve alarms contact your local distributor (see page 16 for details).

Systems using more than 3 or 4 alarms must be very carefully planned to ensure nuisance alarms are not excessive. e.g. from cooking fumes or steam. The following is suggested:

•A Smoke Alarm Locator Switch (model Ei159 for use with Ei141/144/146) or a Smoke Alarm Control Switch (model Ei1529RC for use with Ei161RC/164RC/166RC) should be incorporated into the system and be readily accessible to all occupants so that the source of an alarm can be quickly identified.

•All alarms must be cleaned and maintained regularly.

•A qualified person must be on call to quickly remove any nuisance units (i.e. units with red light flashing rapidly) which are causing all the other alarms to sound.

WARNING: Do not connect these Alarms to any other type of Ei Alarm (apart from those listed above) or to any other model produced by another manufacturer. Doing so may damage the Alarms and could result in a shock or fire hazard.

Wiring must be installed in compliance with local regulations.

In the UK it is recommended that the following coloured cores are used (for example with triple flat 6243Y cable).

The interconnect wire (minimum 0.75mm2 cable) must be treated as if it was Live. It should be insulated and sheathed. A maximum of 250 metres of wire can be used (maximum resistance between detectors 50 Ohms).

Ei168RC, Ei164RC, Ei166RC, Ei161RC specifications

The Aico Ei161RC, Ei166RC, Ei164RC, and Ei168RC are a series of advanced smoke and heat alarms designed to ensure maximum safety within residential and commercial properties. These devices are equipped with innovative technologies that enhance their efficiency and reliability, making them essential components of any fire safety plan.

The Ei161RC is a versatile optical smoke alarm. It employs a highly sensitive optical sensor that effectively detects slow-burning fires, such as those caused by smoldering materials. One of its standout features is the built-in Rechargeable Lithium Cell, which offers a prolonged lifespan and ensures that the alarm remains powered even during power outages. Additionally, the Ei161RC is equipped with a test button that allows users to easily verify the functionality of the alarm.

The Ei166RC goes a step further by integrating a heat sensor alongside its smoke detection capabilities. This dual-functionality is ideal for areas where smoke may be a common occurrence, such as kitchens, as it reduces the likelihood of false alarms triggered by cooking fumes. Like the Ei161RC, the Ei166RC also features a rechargeable lithium cell, making it both efficient and environmentally friendly.

Next is the Ei164RC, which is specifically designed for residential homes and commercial settings that require the highest level of safety from carbon monoxide. This alarm combines smoke detection and carbon monoxide sensing in one unit. Its advanced sensing technology ensures rapid detection of both smoke and harmful gases, ensuring comprehensive safety. The Ei164RC has a user-friendly interface, allowing quick access to essential features.

Lastly, the Ei168RC is tailored for those who prioritize intelligent safety solutions. This alarm not only detects smoke and heat but can also integrate with other alarms in the Aico range, creating a comprehensive safety network throughout a property. Its smart interconnected technology ensures that when one alarm is triggered, all alarms in the system sound simultaneously, providing an immediate alert to occupants.

All four models in this series are designed with ease of installation in mind, featuring a compact, modern design that complements any interior. They are engineered to function reliably with a long lifespan and minimal maintenance requirements. With their intelligent features, advanced technologies, and reliable performance, the Aico Ei161RC, Ei166RC, Ei164RC, and Ei168RC alarms set a high standard for fire safety. Whether for residential use or commercial applications, these alarms provide peace of mind and active protection against fire hazards.
