9V (Optional 10 Year Life Sealed Lithium Battery) Radio-Interlinked Heat Alarm - Ei603CRF

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?

A.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.

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.

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.
