Mains Powered Heat Alarm with Self-Charging 10 Year Back-up Battery - BRK 790MRL
Discontinued Product
The manufacturer has withdrawn from the European market and is no longer supplying compatible alternatives. Since it is not possible to interlink alarms from different manufacturers, the recommended replacement for the whole discontinued BRK 700MRL range is the Aico Ei3000 series.
The BRK 790MRL (also known as 690MRL) mains powered heat alarm with self-charging lithium back-up battery is Kitemarked to the latest British Standards and has a 5 year manufacturer's warranty. Up to 12 smoke and heat alarms from the BRK 700MRL series can be interlinked (via cable) within a single system, allowing all alarms to activate if one is triggered by fire. The 790MRL is suitable for installing in kitchen areas and garages.

Q. I want to install an interlinked smoke alarm system throughout my home, but what type of smoke alarms do I need in different rooms?
A.
We recommend a heat alarm in the kitchen, optical alarms in living rooms and hallway and ionisation alarms on landings.
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. What is the best way to test my alarm?
A.
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?
A.
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. Do you need an electrician to connect mains powered smoke alarms?
A.
It is necessary that an electrician installs mains powered smoke alarms.
