The Jalo Kupu 10 Smoke Alarm in White is a battery powered smoke alarm intended for domestic use and comes with an integral non-replaceable Lithium Metal battery that is guaranteed to last 10 years, which is the maximum recommended lifetime for any smoke detector.

Designed by Harri Koskinen the beautiful Kupu smoke alarm features a sleek modern design and shape, with the textile outer cover giving it a warm soft appearance. It has been designed to fit seamlessly within any home interior and to look visually attractive when on display, to show that fire safety can be both beautiful and functional. The Kupu Smoke Alarm has been designed for use in all rooms of the home, including the office, shed or garage, as well as in moving vehicles such as boats, caravans or motor homes.

Unlike other smoke alarms the entire front surface of this beautifully designed smoke alarm serves as a test button so it is easy to ensure the alarm is working - no ladder needed! The Kupu 10 Smoke Alarm comes with an integral 10 year Lithium Manganese Dioxide battery, which means easy maintenance as it doesn't require any battery changes, and it makes it safer as it means there is no chance of batteries being removed to be used in other devices, something we all maybe guilty of at one time or another! Simply replace the entire unit at the end of 10 years - the smoke alarm will release short beeps to warn of low batteries.

The Kupu Smoke Alarm utilises photoelectric detection technology to sense smoke from different types of fires. The optical detection method works by sensing infrared rays scattered by visible smoke particles. The Kupu Smoke Alarm is equipped with a self diagnostic and checking feature to ensure correct operation through its service lifetime. The device operates so that when there is smoke present, the device will release a loud and continuous warning siren to alert residents.

To avoid unintentional false alarms, the Kupu device will run constant checks by sampling the air several times. However if a false alarm does occur, the Kupu Smoke Alarm is equipped with a silence-function, which silences the alarm temporarily for 8 minutes. All of Jalo's Smoke Alarms are tested and certified by BRE UK.

The Kupu Smoke Alarm features automatic power activation upon installation and can be easily installed one of two ways. Either by 'Fast Installation' using super strong two-sided VHB adhesive tape (3M tape is included with the Alarm) and will take approximately 30 seconds to install, or by Screw Installation - screws and detailed instructions of how to do both methods are included with the product. Although the Kupu Alarm does come with a self-test function, it is still recommended that you test your smoke alarm monthly to make sure it is in working order, and clean it with a vacuum at least once a year.

The Kupu 10 Smoke Alarm is available in a range of 6 colours, including a stunning metal chrome finish and comes packaged in a stylish gift box, making it an ideal gift for a house-warming, for either yourself or friends!
