Selecting Alarm Type

1

 Optical Smoke Alarms are recommended due to their excellent 

response to smouldering fires. If there is likely to be problems 
with steam, contamination or dust build-up, or if there is 
significant risk of a fast burning clean fire an Ionisation Smoke 
Alarm should be fitted.

2

 

Ionisation and Optical Smoke Alarms should be fitted for the 

fastest response to all types of fires.

3

 Some Fire authorities (concerned with the slow response of 

Heat Alarms) advise that Smoke Alarms should be fitted. This 
is acceptable according to BS 5839-6 provided there are clearly 
not going to be problems with nuisance/false alarms. Fit Heat 
Alarms only if nuisance/false alarms are very likely and it is 
acceptable that a warning will only be given by the Heat Alarm 
when there is a very significant flaming fire in the room. If the 
door(s) and windows are not closed to contain the fire and heat, 
it is extremely unlikely that the Heat Alarm would respond before 
a Smoke Alarm sited  outside in the corridor.

 In enclosed kitchens with doors closed.

 Greatly depends on ventilation and distance from source of 

fumes.

Grade D System

The mains powered Smoke and Heat Alarms with battery 
back-up covered by these instructions are suitable for 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

- existing dwellings with poor structural fire precautions, up 

to three storeys, with no floor over 200m

2

- Houses in Multiple Occupation (HMOs) of one or 

two-storeys, with no floor over 200m

2

- 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.
