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. Why do your mains powered alarms have batteries?
A.
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.
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 you need an electrician to connect mains powered smoke alarms?
A.
It is necessary that an electrician installs mains powered smoke alarms.
Q. What sort of smoke alarm system would I need to install for a HMO?
A.
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. Can the mains powered smoke alarm range be connected to mains power via the lighting circuit?
A.
Yes, hard-wired mains powered alarms can be wired to the unswitched live feed of the nearest frequently used lighting circuit.

Very easy to install
Downside of this product is that once the sensors have been radio interlinked the system cannot be added to with additional sensors

just what I needed.
I found the instrcutions confusing and used the mounting plate from the box with the sensor head. I later realized that if using radio to link the alarms this mounting plate could be discarded. The instructions could have this point and saved me some time.

Good product but don't do what I did
This review also applies to the other 3 alarms I purchased. I have a rental property with two mains interlinked alarms and I needed to add two more. To avoid wiring I bought two long life lithium models and replaced the two existing ones with these mains Radio Interlinked models. I wired them into the existing circuit (including wired interlink) and also enabled the radio interlink. All seemed to work fine and the initial test worked fine. However, just before leaving I pressed the test button again and they all went off - but wouldnt stop. It was deafening and it just went on and on. I had to remove all the alarms and reset them to stop it. I guessed that the problem was caused by the fact that the two mains alarms were linked by both wire and radio so I removed the wire link and re-installed them on radio alone. This time it worked OK.
A call to safelincs support confirmed that this was likely to be the case as a feedback loop can occur under these circumstances.
