Smoke and CO Carbon Monoxide Detector HQwear HQ151, Certification UL 217 , 2034

A must-have device for every home heated with solid fuel

Provide yourself and your home with reliable protection against fire. The HQ151 smoke detector works in a range of up to 30 square meters and 360 ° to immediately warn you of a possible danger with an audible and visual signal. Made of fire-resistant ABS plastic - it is extremely durable. It requires 3 AA batteries (not included) to power it, which you only need to replace once a year.

The device works with photoelectric smoke detection technology, which ensures greater sensitivity than standard alarms. When the HQ151 senses a threat, it will let you know in two ways - audibly and visually. It generates a signal with a volume of up to 85dB and activates a red LED indicator. You can be sure not to miss the alert!

The sensor has a display for reading the CO concentration, as well as a test button.

Practical LCD display
The built-in display will show real-time carbon monoxide (CO) concentrations in the ambient air, as well as remaining battery life and alarm operating status.
If a CO concentration of 30-999 ppm exists for a certain period of time, the display will be illuminated in blue and the LED indicator will flash red 4 times every 5.8 seconds.

When the battery capacity is low, the red light flashes once every 10 seconds and the LCD display “LB”

Test/Silence button
Press the "TEST" button, LCD display "CO 0 ppm", then smoke "0.00db/m", the LED flashes and the detector will give a continuous alarm.
The TEST/SILENCE button allows you to test the alarm to make sure it is functioning properly. When false alarms occur, the unit can be silenced with a simple push. Remember to test your alarm every week.
