Pressing the test button for about 10 seconds will discharge the circuitry. Here are some common questions we have been asked by our customers about Ei Electronics and Aico (Ei’s UK operation) mains powered smoke alarms and heat alarms through our fire safety forum.

They provide up to six months alarm operation without mains power.

The memory feature allows an Alarm that has previously activated to be easily identified (the red LED will flash twice every 48s for a 24h period after an alarm activation).Beeping or chirping is normally due to low battery power in the alarm. This beeping most commonly starts at night due to the drop in temperature causing a decrease in battery power.

The Ei2110e also has hardwired and wireless (through the Ei100MRF) Remote Control capability, enabling it to be interconnected to and communicate with compatible Alarms and Devices. Up to 12 Alarms and Devices can be interconnected, which will cause all Alarms to sound when one unit senses fire. An interconnected system will enhance early detection and warning of fire. Features
