FAQs (7)
Q. I want to install an interlinked smoke alarm system throughout my home, but what type of smoke alarms do I need in different rooms?
A.

We recommend a heat alarm in the kitchen, optical alarms in living rooms and hallway and ionisation alarms on landings.

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.

Q. Can a smoke alarm be fitted with a sticky adhesive pad in a let property?
A.

The sticky pad is suitable for all battery operated smoke alarms. However, we cannot judge if battery alarms are suitable for your let property, as let properties usually require mains powered alarms. There is some advice to this in the governments guides to fire risk assessments. http://www.safelincs.co.uk/Fire-Risk-Assessment/ Also see the LACoRS guide for let properties.

Q. Do I need to take out all the batteries in my radio-interlinked alarms before adding a new alarm into the system?
A.

No, you do not need to remove all the batteries. Just simply press the house code button on all the units. Please ensure that the batteries have full power as this could render the house code process incomplete.

Q. is there a different alarm sound for optical and heat sensors to tell you the difference in what kind of fire it is?
A.

There is only one alarm sound type when a fire is detected, when interconnected all smoke and heat alarms will sound. However only the triggered alarm will have a rapidly flashing red indicator.
