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. Do you need an electrician to connect mains powered smoke alarms?
A.
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?
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. When the test button is pressed on an interlinking smoke alarm will this cause all the other units to go off, too?
A.
Yes, by pressing the test button on one alarm all the units in that family will also be activated. To 'teach' the units which other smoke alarms belong to the same family, the smoke alarms have to be set up together during the installation. This is done by pressing a 'housecoding button' or similar process.
Q. If a false alarm goes off can pressing the hush button on any of the interlinking alarms stop all the units beeping?
A.
Show All No, to stop the alarms from sounding the hush button on the unit that started the process needs to be pushed. Pressing any other unit will just silence that one unit. The unit can be identified by the rapidly flashing red LED.
