FAQs (13)

Q. Do the Ei3100RF alarms require anything other than fixing to the ceiling to install them?

A. No, with this series of radio interlinked alarms there is nothing other than pressing the house code button required to install them.

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

A. 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. 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?

A. 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].

Q. Do I need to take out all the batteries in my radio-interlinked alarms before adding a new alarm into the system?

A. No, you do not need to remove all the batteries. Just simply press the house code button on all the units. Please ensure that the batteries have full power as this could render the house code process incomplete.

Easy installation, configuration & good value. Purchased this as an add-on to the EI3100KIT as an alarm in the other side of the L-shaped lounge/diner. Well worth the belt & braces value.
