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.
Q.I purchased 4 alarms for my property recently via Safelinc's website. My electrician has installed them over the weekend.
However we have the following issue:
When you press the test button on the Carbon monoxide alarm the carbon monxide alarm goes off (but no alarm sound is heard on the other 3 connected smoke alarms).
This seems strange given that when you test any of the 3 smoke alarms, an alarm sound can be heard on the carbon monoxide alarm.
Is this meant to be like this?
The alarm models are:
1. Carbon Monoxide Firex 4985
2. Firex Ioisation 4881
3. Firex Ionisation 4870
4. Firex Optical 4985
A.The reason is the relevant British Standard which requires a different alarm sound for CO alarms in comparison to smoke alarms.
To achieve this, the CO alarm in question has a dual sound capability, meaning that
- if a smoke alarm is triggered or tested, the CO alarm detects that a smoke alarm has gone off and will activate one of its two internal sounders (sounding like a smoke alarm).
- if the CO alarm is tested or triggered, only the CO alarm sounds (sounding like a CO alarm). The smoke alarms are in this case not allowed to sound. As said above, this is a stipulation from BSI
