The first of FireAngel's Green Product Initiative, the ST-620 10 year optical smoke alarm has been discontinued to make way for their new generation of smoke alarms. The upgraded FireAngel ST-622 optical smoke alarm features a large test/reset button to ease testing as well as FireAngel's Sleep Easy™ function that temporarily silences low battery and end of life chirps for 8 hours. The FireAngel ST-622 will fit directly onto your existing ST-620 base, making replacing your alarm quick and easy.
Battery: Built-in, lasts the lifetime of your alarm
Warranty: 5 year warranty
Fits directly onto existing ST-620 alarm bases
Tamper-proof battery does not need to be replaced for the life of the alarm
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. 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.
Q. Can a smoke alarm be fitted with a sticky adhesive pad in a let property?
The sticky pad is suitable for all battery operated smoke alarms. However, we cannot judge if battery alarms are suitable for your let property, as let properties usually require mains powered alarms. There is some advice to this in the governments guides to fire risk assessments. http://www.safelincs.co.uk/Fire-Risk-Assessment/ Also see the LACoRS guide for let properties.
