Early detection of slow, smoky fires - with an optical sensing chamber
Optical sensing works by 'seeing' smoke as it enters the sensing chamber, making the alarm responsive to thick, white smoke from slow-burning sources. Sensitive electronics translate the optical signal into a loud alert when smoke density crosses the threshold.
Quicker warning for smouldering fires gives more time to react, especially useful in living rooms and bedrooms. The sensing approach focuses on the types of smoke that can smoulder unnoticed for longer periods.
Fewer nuisance activations from cooking fumes - thanks to high-performance optical sensors
Sensor tuning reduces sensitivity to brief, light vapours so common kitchen activities are less likely to trigger an alarm. User-accessible hush functionality allows temporary silencing when a false alarm occurs.
Fewer interruptions during everyday cooking means less temptation to disable protection. Hush control lets occupants silence a false alarm for a short period, then restores full protection automatically.
Simple upkeep and compliance - with a replaceable 9V battery and certification
Each unit includes a replaceable 9V battery designed for one year of typical use, with a low-battery chirp and LED flash every 32 seconds to signal replacement. Certification to BS EN14604:2005 and CE and UKCA marks confirm compliance with UK domestic standards.
Annual battery replacement and clear low-battery alerts make maintenance straightforward. Certification and a three-year warranty give confidence that the unit meets recognised safety requirements.
