The amber light may flash for one of two reasons; firstly it may be indicating the base is in House Code mode (used while setting up new networks of radio-interlinked alarms). House Code mode is automatically exited after 30 minutes or can be manually exited by inserting a screwdriver in the House Code slot and holding the House Code switch until the amber light turns on. Once a solid amber light appears release the switch and the amber light should stop flashing.

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. How to stop beeping from Ei / Aico mains powered smoke and heat alarms Ei141, Ei144, Ei146, Ei150, Ei151, Ei154, Ei156, Ei161, Ei164, Ei166 Ei Electronics and Aico products have usually a 5 year manufacturer’s warranty during which they will be repaired or replaced free of charge if suffering from faults or defects caused by manufacturing issues. Aico’s telephone number is 01691 664100. They deal with warranty cases for the mains powered ranges. Smoke alarm starts to beep in the middle of the night In an interlinked system when one unit detects smoke, all alarms sound. To silence the alarms in case of a false alarm, press the hush button on the unit that has detected the smoke. This will silence all interlinked alarms.Unique dust compensation feature (The alarm automatically adjusts for any contamination within the optical sensor chamber) The E2110e can be interconnected via hardwire or wirelessly with the RadioLINK+ module Ei100MRF (sold separately) enabling it to communicate with compatible Ei Alarms and accessories. Up to 12 devices can be interconnected. The large Test and Hush button on the front of the product allows for safe and easy operation using a cane or a broom. 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. One of the Ei168 radio bases flashes amber light every 10 seconds. All other bases in the group are fine. Solution

The most common source of false alarms in smoke detectors is contamination (such as dust and small insects) within the sensor chamber. Cleaning the unit by either vacuuming around the central detection chamber or blowing it out with the cold setting on a hair dryer normally resolves this issue. Up to twenty alarms can be interconnected which will cause all alarms to sound when one unit senses fire. A new Ei161 alarm has been installed but is randomly emitting short (1-2 seconds) alarm beeping sounds. SolutionThe radio interlinked smoke alarms of the Ei140 series alarms, while having been fitted by an electrician, are not interconnecting. Solution For most Ei Electronics mains powered smoke alarms, a replacement kit is available containing a compatible smoke alarm, and in the case of Ei140 and Ei160 alarms, the new head just slides onto the existing base without the need for an electrician. You may find this range of videos, showing how to change batteries and detector heads, useful. We also offer replacement smoke detector heads so that you can change your alarm without the need to call in an electrician. General smoke alarm problems If a smoke detector is removed from the base and the battery is also removed, the alarm might still hold some residual charge and beep for up to a minute. Pressing the test button for about 10 seconds will discharge the circuitry.
