2.Screw the pattress to the ceiling after first removing the required knock- out and bringing the house wires through it (see figure 1). If the central knockout is being used, seal around the wires (and the openings at the rear of the pattress) with silicone or similar to prevent air draughts affecting the smoke entering the alarm.

3.Connect the house wires (L - Live, N - Neutral and IC - Interconnect, if it is being used) to the terminal block on the pattress. If an EI 161R or EI 166R (with remote TEST/HUSH) is being installed, attach the “R” wire from the EI 152 (see the EI 152 instructions) to the terminal marked “R” in the pattress (see figure 1). If the EI 161R or EI 166R is being used with a man- ual call point MCP400 or MCP400A then connect the R terminal to the call point (see figures 1& 2). Otherwise do not connect anything to the ”R” ter- minal.

4.Connect the three wires (L, N and IC) from the pattress connector block to the connectors on the Smoke/Heat Alarms mounting plate. Connect the earth wire (if present) from the house wiring directly to the terminal on the mounting plate. Replace the cover over the terminal wires.

5.Screw the mounting plate to the pattress pillars using the two screws supplied.

6.Slide the alarm on to the mounting plate.

7.Connect the mains power – the green LED light on the alarm should be on. When the test button is pressed the horn should sound.

If an EI 128R pattress with relay is being used, replace the EI 127R with the EI 128R and follow the instructions supplied with the EI 128R.

Ei Electronics is renowned for its commitment to safety and innovation in the realm of smoke and carbon monoxide alarms. Among their popular products are the EI 127, EI 166R, EI 127R, and EI 161R models. Each of these devices brings unique features and advanced technologies to enhance home safety and protection.

The Ei 127 is a high-quality optical smoke alarm that utilizes advanced optical sensing technology to detect smoke particles quickly and accurately. Its design ensures minimal false alarms, making it ideal for areas prone to cooking fumes. With a built-in rechargeable battery that lasts up to 10 years, the Ei 127 provides continuous protection without the hassle of frequent battery replacements. Additionally, features like a large test button and a mute function enhance its usability, ensuring users can easily maintain it.

Moving on to the Ei 166R, this model is a carbon monoxide alarm equipped with a powerful electrochemical sensor. It is specifically designed to detect harmful levels of carbon monoxide, a silent and lethal gas produced by incomplete combustion. The Ei 166R features a 10-year life span for its battery and offers an easy-to-read LED indicator for alerts, along with a built-in test button for regular functionality checks.

The EI 127R is another smoke alarm that shares many characteristics with the Ei 127 but comes with additional connectivity features. It can be interlinked with other Ei alarms, such as carbon monoxide detectors, creating a comprehensive network of smoke and gas detection throughout the home. This interconnectivity is particularly advantageous in larger spaces, allowing residents to receive alerts from multiple locations, thereby enhancing overall safety.

Lastly, the EI 161R is a versatile multi-sensor alarm that can detect both smoke and carbon monoxide, making it a comprehensive choice for home safety. This model employs a combination of optical sensing for smoke and an electrochemical sensor for carbon monoxide, providing dual protection in a single unit. The EI 161R also features a large display, emphasizing user-friendliness, ensuring that critical information is easily visible.

In summary, Ei Electronics has produced a range of innovative smoke and carbon monoxide alarms, such as the EI 127, EI 166R, EI 127R, and EI 161R. Each model is equipped with state-of-the-art technology, user-friendly features, and long-lasting reliability, making them essential devices for maintaining safety in every home. With their focus on quality and functionality, Ei Electronics continues to set the standard in residential safety alarms.
