Improved Audibility
The effectiveness of a Category LD2 (UK) system can be significantly enhanced if an additional Alarm
(interconnected) is installed in the master bedroom. This will help ensure that a responsible person
will quickly be alerted to a fire and can arrange for an orderly evacuation of children and other
vulnerable occupants.
Grade D System
The mains powered Ei3024 Multi Sensor Fire Alarm, Ei3016 Smoke Alarm and Ei3014 Heat Alarm with
rechargeable battery back-up, covered by these instructions are suitable for the requirements for a
Grade D System.
A Grade D system is needed for:
- new or materially altered dwellings up to three-storeys, with no floor over 200m
2
in area.
- Existing dwellings with poor structural fire precautions, up to three storeys, with no floor over
200m
2
in area.
- Houses in Multiple Occupation (HMOs) of one or two-storeys, with no floor over 200m
2
in area.
- Individual dwellings units of two or more rooms in HMOs.
Check that a Grade D system is adequate for the dwelling into which the system is being installed.
