- 7 year warranty, 10 year alarm life, kitemarked and ce marked
- In fault mode the amber led will blink every 30 seconds and there will be a chirp every 30 seconds. there is no fault when the amber led simply illuminates when the test button is pressed.
- Continuous monitoring for co with a loud alarm on detection
- Battery operated (2 replaceable aa batteries supplied)
- Please note: as stated in the product manual, when the test button is pressed both the green led and amber fault led will come on. this shows that both are working. it does not mean the alarm is faulty.
