This mains powered Radio-interlinked heat alarm does not require any cable to interlink with other Ei140 series smoke and heat alarms and is ideal for extensions, renovations, and small let properties. Heat alarms are unaffected by smoke and fumes, making them ideal for kitchens and garages where smoke alarms are likely to false alarm.
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?
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. How can we test the alarm to make sure it is working?
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?
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. How do you wire in the Ei140/Ei160 series of smoke alarms?
To wire the units correctly you would use 2 core and earth cable to the first unit and 3 core and earth to the interconnected units. The alarms do not have to be earthed but a brass screw connector is provided so that the earth can be safety terminated.
Q. I have added an Ei168RC164RC wireless linked heat detector to my garage some time after the installation of various other wireless Ei160 detectors in the house. What do I have to do to get the system to recognise the new detector please?
To get the Ei168RC164RC to communicate with the existing alarms, you would need to housecode all the units again. Press the housecode button on the new Ei168RC base and on each of the existing units.
