Ei Electronics Ei225E Surface-mounted Electrochemical detector

IP20, 85dB, 230V, 135 x 105 x 71mm, LED, White <b>Product Description</b>
The Ei225EN is a Carbon Monoxide (CO) alarm powered by 230V AC mains power.

The Ei225EN CO alarm uses a proven electrochemical cell type sensor which checks CO concentration every 50 seconds. All units are individually calibrated and tested in CO gas in order to ensure accuracy and they're covered by a lifetime (5 year) guarantee.

The CO alarm is housed in a slimline casing and can be easily secured to a wall or ceiling, with all necessary fixings supplied.

As well as being easy to install and maintain, the alarms have a vitally important memory feature which records if CO has been detected whilst the occupier was away.

An easy to use Test/Hush button allows the user to check that the horn and electronics are working and to silence nuisance alarms.

<b>Operation</b>
- The green indicator will illuminate to indicate that the unit is receiving mains power
- The horn will sound and the red indicator will flash at different speeds to indicate the presence of various levels of CO gas – slow flash indicating low levels and rapid flash to indicate high levels
- The horn will beep and the amber indicator flash every 40 seconds to indicate a fault
- The “Test/Hush” button will either silence false alarms (if briefly pressed) or perform a unit self test (if pressed and held). Note that the alarm cannot be silenced when sensing a CO level of 300ppm or above
- Memory Feature - when the test button is pressed the horn will sound and the red indicator will flash at a specific rate to indicate the level of CO previously detected.
