Marine Carbon Monoxide Detector with Customizable Alarms, LED Indicator Light and 100dB Loud Alarm, Including a 12V 3A Normally Closed Relay, Provide You with Additional Security Protections HMCOA-01
MULTIPLE ALARM INDICATORS: Carbon monoxide (CO), being colorless and odorless, is often difficult to detect when leaked, yet it poses significant harm to the human body. Our alarm system is designed to promptly detect and provide multiple indicators, including a red LED indicator light, LCD screen displaying alarm symbols, and an alarm sound exceeding 100dB. This effectively alerts you to the danger of elevated carbon monoxide levels through both visual and auditory signals
CUSTOMIZABLE ALARM THRESHOLD: You can set the alarm threshold using the SET key (range 10--500PPM). The default value is 400PPM, and the alarm mechanism is triggered when the detected CO value is continuously >= 400ppm for 30 seconds. This adjustability allows the alarm to adapt to different environments and provide more personalized safety performance based on carbon monoxide concentration standards
SUITABLE FOR HIGH-HUMIDITY ENVIRONMENTS: The internal circuit of the alarm is coated with three-proof paint and undergoes waterproof treatment, enabling it to operate normally in high-humidity conditions. This ensures the reliable performance of the product under various harsh conditions
SAFETY PROTECTIONS: When the system voltage falls below 7V, the alarm will indicate a power failure and cease operation. The alarm unit is equipped with a normally closed 12V 3A relay, which can be connected according to your needs to shut down a generator or open a gas solenoid valve, providing you with an additional safety protections
INSTALLATION ADVICE: Alarms are widely used in environments such as RVs and cabins. It is recommended to install the alarm at least 4 inches above the ground. Regularly test and maintain the alarm to ensure its proper functioning
