Alarms at temperatures of 58°C and above
No central alarm panel needed
RF range 150 metres (minimum) in free space and up to 30 metres in buildings. Larger buildings can easily be covered, as the units can act as repeaters (daisy-chaining)
A maximum of 12 units can be interlinked
Digitally coded to avoid interference with neighbouring systems
Mains powered Ei Electronics smoke and heat alarms require a 230V AC power supply and up to 12 alarms can be hardwire interlinked in one system.
To obtain a mains power supply, each alarm can be connected to the nearest lighting circuit using 2 core and earth cable with a separate, dedicated interlink cable connecting alarms where applicable. However, if possible it is recommended that any alarms connected via interlink cable are all powered from a dedicated circuit from the distribution board using 3 core and earth cable for safety during maintenance, as the interlink cable will carry power from live alarms on other power circuits. Please see the diagram below:-
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.
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. How can we test the alarm to make sure it is working?
A.
The manufacturer's recommendation is to test the alarm by pressing the test button. This will simulate a heat input at the heat sensor. You can also test it with a hair dryer but make sure that the hairdryer is kept away at a suitable distance from the alarm. Do not attempt to test the alarm by using open fire or excessive heat as this may damage the unit.
Q. Is it possible to have a heat alarm mains powered radio interlinking alarm interconnect with battery powered radio-interlinked alarms?
A.
Yes this entirely possible. The Ei140 series with RF base is mains powered and these are compatible to interlink with the battery operated Ei3100 series. Please view the interconnection overview on either of these alarms for further details.
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.

Works fine, but secure syncing with other units tricky to verify.
Works fine, but the yellow LED that flashes to confirm radio sync is too quick, and with 12 units connected, it's almost impossible to confirm you are secure with the other alarms - although this is just a security gizmo - all alarms will sound if in radio range of each other. Slow down the flash rate please EI, with a long pause between the count. Better still, a bi-colour LED to indicate the count start ...
