Please note: the packaging may show a product code of 770MBX and include a push-fit base but the alarm itself is still a 670MBX, as shown on the sticker on the back of the alarm head, and it is still compatible with existing twist-fit bases. If you are having difficulties with the removal of the alarm from the push-fit base, please see our video that demonstrates the removal.
Q. Do I need an ionisation or optical smoke alarm?
We recommend using an optical smoke alarm in hallways, as these are less likely to go off because of cooking fumes from a connected kitchen. Optical smoke alarms are also ideal for living rooms, dining rooms, bedrooms, as they are good at detecting smouldering fires from soft furnishings. For landings we recommend ionisation alarms. Heat alarms are designed for kitchens and garages. No alarms should be installed in bathrooms.
Q. Why do your mains powered alarms have batteries?
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 I put my smoke alarm on the wall, or must it be mounted on the ceiling?
The best location to install your smoke alarm is in the centre of the ceiling rather than on the wall. During a fire, smoke initially rises and then spreads to the sides of the room. By installing the alarm on the ceiling, this ensures that you receive the earliest possible warning of a fire.
Q. What is the best way to test my alarm?
We recommend testing alarms by pressing the test button built-in to the unit, as this is designed to simulate the detection of the target stimuli (usually smoke, heat, or CO) at the alarm sensor. You should test your alarms regularly to ensure they are protecting building occupants, preferably every week. For more detailed guidance, check the manual included with your alarm.
Q. How long do smoke alarms last before needing replacement?
It is recommended that smoke alarms are replaced after 10 years. This is because the sensors in the smoke alarms become less sensitive and may not activate when a fire is present.
