Product Overview

This alarm is the radio-interlinked version of the Ei2110e, a multi-sensor fire alarm that contains two separate sensing elements – optical and heat. As the unit monitors two different by-products of fires (smoke and temperature), its response to all types of fire is vastly improved over traditional single sensor alarms and reduces the number of false alarms in the premises.

  • Suitable for installations complying to BS 5839-6: 2013 Grade D, E and F
  • Each unit consists of a radio-frequency module and the Ei2110e alarm sensor
  • Suitable for living rooms, bedrooms, hallway, landings (not kitchen or garage)
  • 230V Hard-wired alarm with two sensors - optical smoke and heat
  • Re-chargeable lithium battery backup guaranteed for 10 years

Wiring Explained

The radio interlinked Ei2110 multi-sensor alarm requires a 230V AC mains power supply to each unit. Up to 12 Ei2110 and Ei160 series of alarms can be wirelessly interlinked 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 interlink. Please see the diagram below:-

FAQs (7)

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?

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

A. BS 5446-1:2000 was withdrawn in 2008 and replaced by BS EN 14604:2005 to conform with European standards. These alarms are fully compliant with BS EN 14604:2005.

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.

Q. Does the Ei2110 multi sensor model need to be fitted by a qualified electrician?

A. We would always recommend a qualified electrician to fit these mains powered smoke alarms for you .

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.
