FAQs (11)
Q. Please could you explain how the repeater function works on the Aico/Ei radio interlinked detectors.

Hello. The radioLINK repeater function allows the smoke alarm to "repeat" the radio frequency signal around obstructions. This stops the signal from becoming blocked and ensures that all interlinked alarms can be reached. This repeater function is built-in to the the Ei168RC radioLINK base (with Ei140, Ei160 or Ei2110 alarm), the Ei600 series of radio interlinked battery powered smoke and heat alarms as well as the Ei262 and Ei208WRF carbon monoxide alarms as standard. When house coded, the system works itself out which alarms are to act as repeaters - it's not something you set up yourself.

Q. What is the difference between Ei3100RF radio-interlinked smoke alarm series and the Ei600 series of radio-interlinked smoke alarms? Why does one cost much more than the other?

The EI600RF series are a later model and on top of all the features that the Ei3100RF offers, the series has the possibility to use the locate feature in the control switch, making the product more similar to a BS5839 part 6 Grade A alarm system. Additionally, the Ei600 series smoke alarms are offered with a true ten year life sealed lithium battery which makes the alarms acceptable in most circumstances as a BS5839 part 6 Grade D fire alarm system. This offers a substantial saving to customers, as it replaces the need for an electrician installing mains powered alarms.

Q. If the radio interlinking signal on one unit fails will the units still work as stand alone units.

Yes, should the radio interlinking signal fail the units will continue to sound independently should they detect a fire.

Q. Can a wireless router interfere with the radio interlinked alarms?

A wireless router is very unlikely to interfere with the signal of your radio interlinked alarms, as the RF signal of the smoke alarms is digitally coded.

Q. Do the radio interlinked units give out a constant signal all the time and does this decrease the battery life more than a non-interlinked alarm?

Yes, radio interlinked alarms are periodically sending and receiving signals from other units in the network and therefore the life of the battery is reduced. Units with alkaline batteries should have the batteries are changed annually [unless they are fitted with a sealed 10 year battery as eg in the Ei600RF series].
