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.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.

This was an exact replacement for the old Firex FADC 250 detector which expired after 10 years. Took 5 mins to replace. Strongly recommend Safelincs.
