Product Overview

The Ei208 is a stylish CO alarm that can be wall or ceiling mounted and (due to its flat base) can also be free standing. The detector has an intelligent 'low volume test' which allows the user to test the units functionality without sounding at 85dB like most other alarm units on the market. As carbon monoxide can temporarily spike due to vehicle exhaust fumes or a gas cooker striking up, CO detectors only sound the alarm after a specific amount of time has passed – however, the Ei208 has a pre-alarm feature where the red alarm LED will start to flash as soon as CO is detected at concentrations of 43ppm or higher.

A neat unit which can be linked to heat and smoke alarms.

Reviewed by:

Good monitor, poor quality screws for fixing it. Monitor looks fine and load alarm, but 'don't spoil the ship for a ha'p'orth of tar'. This monitor is sold for caravan and boat use but the screw fixtures provided with it are not corrosion resistant.
