Ei 131 Smoke Alarm Install A Ei159

This is the latest Ei141RC detector - now capable of interlinking with the Ei1529RC remote control switch.

The Ei141RC replaces the previous Ei141 model but can still be used to extend and interlink to an existing Ei140 system.

Mains powered Ei Electronics smoke and heat alarms require a 230V AC power supply and up to 12 alarms can be hardwire interlinked in one system.

To obtain a mains power supply, each alarm can be connected to the nearest lighting circuit using 2 core and earth cable with a separate, dedicated interlink cable connecting all alarms.

However, if possible it is recommended that the alarms are all powered from a dedicated circuit from the distribution board using 3 core and earth cable for safety during maintenance, as the interlink cable will carry power from live alarms on other power circuits.

Lithium batteries will usually last 5x longer than their alkaline counterparts, achieving around 5 years lifetime.

Some lithium cells are also rechargeable, and when used in a mains-powered alarm may last for the entire functional lifespan of the alarm.

These batteries are specialist components which are designed to not be removed or need replacing by the user, and have been tested by the alarm manufacturer to ensure they last for the lifetime of the alarm.

Please Note: the actual lifetime of your batteries depends on how often the alarms are tested or activated, as sounding the alarm draws more power than when the alarms are waiting to detect fire.

Otherwise try cleaning the alarm around the vents with a vacuum nozzle.

The Ei144 heat alarm gives a fire warning when the temperature at the unit reaches 58C.

Heat alarms are ideal for use in kitchens and garages, where the use of optical or ionisation alarms would lead to unwanted nuisance alarms.

You should also install a Ei159 locator to allow you to find out if the alarm was triggered by CO gas or by fire.
