Technical Data Sheets

The following technical data sheets are available for this product:

Q.Can the mains powered smoke alarm range be connected to mains power via the lighting circuit?

A.Yes, the mains powered alarms are hard wired into the lighting circuit.

Q.The smoke alarm is mains powered do you need an electrician to connect them?

A.It is necessary that an electrician installs mains powered smoke alarms.

Q.Are there any restrictions to the distance a radio-interlinked smoke alarm will work?

A.Most radio-interlinked alarms have a range of 150 meters in an open space and up to 30 meters in buildings. The thickness of the walls and partitions will affect the travel distance of the signal. Most units can be set up as a 'repeater' which will increase the distance by a further 30 meters.

Q.Why do your mains powered alarms have batteries?

A.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 the Modum escape ladder be used with a bottom release pin to climb up from a basement to ground floor?

A.The Modum ladder can be supplied with either a top or bottom release pin.
