Product Overview

Mains powered heat alarm with hush button from Ei Electronics, Ei144e, is suitable for installation in kitchens and garages where a smoke alarm would be more prone to false alarms.

The Ei144e replaces the previous Ei144 models but can still be used to extend and interlink to an existing Ei140 system.

Wiring Explained

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.

FAQs (5)
Q. How can we test the alarm to make sure it is working?
A.

The manufacturer's recommendation is to test the alarm by pressing the test button. This will simulate a heat input at the heat sensor. You can also test it with a hair dryer but make sure that the hairdryer is kept away at a suitable distance from the alarm. Do not attempt to test the alarm by using open fire or excessive heat as this may damage the unit.

Q. How do you wire in the Ei140/Ei160 series of smoke alarms?
A.

To wire the units correctly you would use 2 core and earth cable to the first unit and 3 core and earth to the interconnected units. The alarms do not have to be earthed but a brass screw connector is provided so that the earth can be safety terminated.

Q. Can I upgrade an existing Ei140 series base with an Ei3000 series alarm?
A.

Yes, the new Ei3000 series is fully backward compatible and will work directly with the the Ei140 series base. Both the power supply and the interlink with any remaining Ei140 alarms will continue to work with your new Ei3000 alarm.

Q. My detector does not have "RC" stated at the end of the code. What does this stand for?
A.

The RC just refers to "Remote Control" as the unit can be fitted to a radio-frequency base for interconnection. The model hasn't changed but the manufacturers changed the product code slightly in reference to this.

Q. For mains powered Aico smoke and heat alarms, when the electricity supply fails and the back up battery takes over, please can you tell me how long the battery will last in this situation?
A.

For mains powered Aico alarms with a new, fully charged lithium back up battery, the battery would last approx. 3-6 months without a mains supply. For mains powered Aico alarms with a standard alkaline back up battery, the battery would last up to a year without mains supply. If the alarm has been installed with an Ei168RC radio frequency base, please note that the Ei168RC back up battery would last approx 2 months if the power fails.
