    FAQs (1)
    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
