The Ei160RC smoke alarms can be interconnected using cable, allowing all the alarms to sound if a single unit detects a fire. This interconnection feature provides occupants with the earliest warning in case of an emergency.

Wiring Explained

The Ei160 series of smoke and heat alarms require a 230V AC mains power supply. Up to 12 alarms can be hard wire interconnected on one circuit.

To obtain a mains feed, the first alarm can be connected to the nearest lighting circuit using 2 core and earth cable. From this alarm, 3 core and earth cable is required for all additional alarms, which allows for the hard wire interconnection to work. Please see the diagram below:-


Alternatively, the alarms can be hard wired using a dedicated circuit from the distribution board.

FAQs (7)
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. Can I add a CO detector to a smoke alarm system with Ei160 alarms?

Yes, even though the Ei160 series has been discontinued, the new Ei3000 series of alarms are compatible with any remaining 160s you still have. This includes the Ei3018 carbon monoxide alarm. We also recommend that you install a Ei1529RC locator switch as well which will allow you to find out whether an alarm is caused by CO gas or a fire.

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. Can I upgrade an existing Ei140 series base with an Ei3000 series alarm?

Yes, the new Ei3000 series is fully backward compatible and will work directly with the the Ei140 series base. Both the power supply and the interlink with any remaining Ei140 alarms will continue to work with your new Ei3000 alarm.

Q. Does this alarm conform to BS 5446 part 1 as recommended by the Fire Service?

BS 5446-1:2000 was withdrawn in 2008 and replaced by BS EN 14604:2005 to conform with European standards. All of our alarms containing a smoke detector (smoke only, smoke & heat, smoke & CO) are fully compliant with BS EN 14604:2005. They also comply with any other relevant standards relating to their other detection capabilities.
