The Ei3024RF is a mains powered multi-sensor alarm with a self-charging lifetime back-up battery. Fitted with both optical smoke and heat sensors, this alarm allows hybrid interlinking (wired or wireless) with up to 12 compatible devices. It is also fitted with intelligent software, allowing it to detect all fire types and the lifetime back-up battery ensures that if mains power is lost, the alarm will continue to function. AudioLINK allows you to extract real time data from the alarm directly to smart phone. Also fitted with a combined test and silence button, the alarm is supplied with an Ei3000MRF SmartLINK module to allow for radio-interlinking between alarms.

Suitable for living rooms, bedrooms, hallways, landings and dining rooms (not suitable for kitchens or garages)
Multi-sensor alarm containing both optical smoke and heat for detection of all fire types
Hybrid (wired or wireless) interlinking with up to 12 compatible devices
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. Do I need an ionisation or optical smoke alarm?
We recommend using an optical smoke alarm in hallways, as these are less likely to go off because of cooking fumes from a connected kitchen. Optical smoke alarms are also ideal for living rooms, dining rooms, bedrooms, as they are good at detecting smouldering fires from soft furnishings. For landings we recommend ionisation alarms. Heat alarms are designed for kitchens and garages. No alarms should be installed in bathrooms.
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.
Q. Can I put my smoke alarm on the wall, or must it be mounted on the ceiling?
The best location to install your smoke alarm is in the centre of the ceiling rather than on the wall. During a fire, smoke initially rises and then spreads to the sides of the room. By installing the alarm on the ceiling, this ensures that you receive the earliest possible warning of a fire.
Q. Do you need an electrician to connect mains powered smoke alarms?
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?
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.
