The Ei160RC series of mains powered radio-interlinked alarms contain a sealed lithium back up battery that lasts the life of the alarm. Supplied with a radio-frequency base plate with a 30m signal range, up to 12 Ei160RC radio-interlinked smoke alarms can be wirelessly connected within one system. Unlike traditional wired connection systems, the radio-interlinked alarms save time, cost and mess during installation, and the sealed lithium battery stops attempts of battery removal.

Please Note: These units use the radio-interlink frequency 868.499MHz. This bandwidth is restricted for safety products, therefore the chances of interference should be limited.

The radio interlinked Ei160 series of alarms require a 230V AC mains power supply to each unit. Up to 12 alarms can be wirelessly interconnected by radio signal.
To obtain a mains feed, each alarm can be connected to its nearest lighting circuit using 2 core and earth cable. Please note that the separate lighting circuits must have a permanent live supply to all alarms. Radio frequency signals are then used for the wireless interconnection. Please see the diagram below:-
Q. For mains powered Aico smoke and heat alarms, when the electricity supply fails and the back up battery takes over, please can you tell me how long the battery will last in this situation?
For mains powered Aico alarms with a new, fully charged lithium back up battery, the battery would last approx. 3-6 months without a mains supply. For mains powered Aico alarms with a standard alkaline back up battery, the battery would last up to a year without mains supply. If the alarm has been installed with an Ei168RC radio frequency base, please note that the Ei168RC back up battery would last approx 2 months if the power fails.
Q. Please could you explain how the repeater function works on the Aico/Ei radio interlinked detectors.
Hello. The radioLINK repeater function allows the smoke alarm to "repeat" the radio frequency signal around obstructions. This stops the signal from becoming blocked and ensures that all interlinked alarms can be reached. This repeater function is built-in to the the Ei168RC radioLINK base (with Ei140, Ei160 or Ei2110 alarm), the Ei600 series of radio interlinked battery powered smoke and heat alarms as well as the Ei262 and Ei208WRF carbon monoxide alarms as standard. When house coded, the system works itself out which alarms are to act as repeaters - it's not something you set up yourself.
Q. Does this alarm conform to BS 5446 part 1 as recommended by the Fire Service?
This recommendation has been superseded by BS 14604:2005. All of our smoke and heat alarms conform to this standard in accordance with the Kitemark.
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.
Q. I need to connect my EI160 alarms wirelessly to my sprinkler system so that if the sprinkler activated, it would send a signal to my alarms to sound. What can I use
You would connect the EI408 switched input to the sprinkler system which would activate the EI168 wireless base to sound the alarms
Q. My ceiling light is on a dimmer switch. Can I still power my radio-interlinked mains smoke alarms from this lighting supply?
In modern housing the lighting circuit will travel around your house with the lights being fed from it. Between the circuit and the light will be a switch (or in this case a dimmer) which will control the light. Your mains powered alarms are connected directly to the circuit and have constant power, so are not affected by switches or dimmers.
In older homes that have not had the electrics updated this may not be the case so it is advisable to consult an electrician.
Q. Can the Ei160 RF series be connected to a CO detector?
Yes, you can use either the battery powered Ei208WRF CO detector or the mains powered Ei262 CO detector. We also recommend that you fit a Ei412 locator switch to allow you to find out if an alarm was caused by CO gas or a fire!
Q. Can the mains powered smoke alarm range be connected to mains power via the lighting circuit?
Yes, hard-wired mains powered alarms can be wired to the unswitched live feed of the nearest frequently used lighting circuit.
Q. What sort of smoke alarm system would I need to install for a HMO?
BS 5839-6 recommends that one or two storey HMOs with an individual floor area of no more than 200sqm (not the total of both floors) should have a Grade D smoke alarm system installed. Grade D refers to mains powered smoke alarms with a back up battery power supply. The alarms can be interlinked either by wire or by radio signal and the system does not require a separate fire alarm panel. For HMOs of 3 storey or higher, a Grade A panel system would need to be installed. This can cover the whole of the building, or can be used just for the communal areas with a separate Grade D system installed for the individual dwellings. For both applications, the level of cover should be a minimum of LD3 (in all escape routes) but this may change according to the fire risk assessment.
Q. Do you need an electrician to connect mains powered smoke alarms?
It is necessary that an electrician installs mains powered smoke alarms.
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. Why do your mains powered alarms have batteries?
All our mains powered alarms have a battery backup. Although mains powered alarms without this option do exist (BS5839 part 6 grade E), we regard them as far too dangerous, as a lot of fires are caused by electrical faults leaving the building unprotected against fire if the smoke alarms have no backup battery. With our mains powered alarms you will always be protected.
