The following technical data sheets are available for this product:
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.
Q. Where more than one radio-interlinked battery operated smoke alarm is installed, if the battery in one alarm failed would the other alarms be affected?
A. If one alarm was to malfunction the other units would not be affected, if it was due to alarm failure. If the fault was with the radio-interlinking signal, then all alarms that are in the chain after the faulty alarm would be affected and they would not go off.
Q. If an EI3105RF alarm is installed in a thatch roof space and one is installed on the landing of the house, will the second unit sound should there be a fire detected in the roof space?
A. Yes that is correct, the radio frequency technology in these alarms allows them to be connected wirelessly. This is acheived by following the step by step house coding procedure in the instructions, the procedure ensures that all alarms in the series are 'tuned in' to each other allowing them to pass messages on. If a fire was to occur in your roof space the alarm located up there would sound and send a message to the alarm downstairs which would then sound to alert anybody in the premises.
Q. Are the battery radio-interlinked smoke alarms suitable to install in a four storey house with thick walls?
A. Our radio-interlinked smoke detectors have a radio frequency range of about 30 meters in buildings. This means that as long as the detectors are all within 30 meters of each other, the interconnection should be achieved. Some of the RF smoke alarms can also act as repeaters, which means that larger distances can be achieved. So, a four storey house should normally be suitable for RF install.
Q. Do batteries in radio-interlinked alarms expire quicker than those in normal alarms?
A. Batteries in radio-interlinked alarms do expire quicker than in other smoke alarms. RF smoke alarms are, however, also available with a 10 year sealed long life lithium battery. This battery will last for the 10 year life of the smoke alarm.
Q. Does the Ei3100 battery operated radio linked series have a hush button? If not how are false alarms dealt with?
A. There are three different alarms that make up the Ei3100 series. The Ei3100 optical alarm does have a hush button, which can be pressed to reset the alarm should a false alarm occur. The ionisation and heat alarms do not have hush buttons. Should either of these alarms trigger a false alarm, due to cooking fumes for example, the alarm can be silenced using a folded newspaper to fan underneath it. To identify which alarm has triggered the false alarm it is the unit with a rapidly flashing red LED.
Q. Is the Ei3105RF a complete smoke alarm or does it need a base?
A. The Ei3100RF series of battery operated smoke alarms are complete alarms, they do not require base plates to make them radio interlinked.
Q. Do the three types of Ei3103 alarms interconnect with each other?
A. Yes, the Ei3103 range, Ei3100RF - Ionisation Smoke Alarm Ei3105RF - Optical Smoke Alarm Ei3103RFU - Heat Alarm, interconnect with each other. If one sounds it will send a radio-signal to the other units and they will then be activated.
Q. Are there any restrictions to the distance a radio-interlinked smoke alarm will work?
A. Most radio-interlinked alarms have a range of 150 meters in an open space and up to 30 meters in buildings. The thickness of the walls and partitions will affect the travel distance of the signal.
