Carbon Monoxide is a colorless, odorless, tasteless and highly toxic gas. It will reduce the oxygen in body’s hemoglobin and cause damage to the brain. Our QA23 is equipped with a precise and low power-consumption sensor. With high efficiency microprocessor-based analysis, it can be triggered under different carbon monoxide concentrations.
Characteristics
- High luminous dual LEDs to indicate different status.
- Green LED to confirm the unit is under normal operation.
- Each visible and audible warning has 4 modes to easily identify current status.
- Test button for alarm simulation.
- Dual power input: 12VDC and 24VDC operation in the same unit. No adjustment is required.
- Optional 110VAC or 220VAC adaptor is available.
