Product Information

The Cavius 3003-005 is a high performance thermal heat alarm combined with superior product design to produce the world's smallest heat alarm at just 40mm.

It is powered by a 10 year longlife sealed lithium battery pack which removes the need to replace batteries during the alarm lifespan. The alarm emits a penetrating 85dB(A) sound output at 3 metres when triggered, includes a 10 minute hush / silence function, 30 day low battery warning tone and employs the smart clip ceiling fixing unique to Cavius for fast and easy installation. This is all backed up by a full 10 year warranty to cover the entire life of the alarm.

The Cavius 3003 heat alarm is designed specifically for use in areas where a fire is more likely to emit flame and heat more than smoke such as in kitchens, garages and workshops. It is ideal in these locations where smoke alarms would be subject to false alarms and provides a suitable method of detection.

Manufactured using the highest quality components, the Cavius 3003 is designed to ensure quality, reliability, stability and 100% operation during the lifespan of the alarm.

After significant investment in building, renovating or redecorating your home, there is no better way to complement your design and protect your family than with the aesthetically pleasing Cavius range.
