Hear an Alarm From Anywhere: If one alarm detects smoke or dangerous CO levels, all wireless interconnected units will activate, ensuring the earliest possible warning.
Wide Coverage for Full Home Protection: Up to 24 X-Sense Link+ devices can be interconnected to create a wireless safety network for your entire house.
2-in-1 Protection: Equipped with both a photoelectric smoke sensor and an electrochemical CO sensor to provide reliable protection against both smoke and CO.
Built-In 10-Year Battery: Features a built-in 10-year lithium battery, so you’ll never need to worry about replacing batteries during the lifetime of the unit.
Real-Time CO Readings: The smoke and carbon monoxide alarm displays real-time CO levels from 30–999 ppm (parts per million) taken from the surrounding air, as well as battery level and working status.

Remote CO2 sensor probe w/photocell & 15' data cable lets you take readings from proper grow room locations..
Fully customizable PPM deadband and CO2 setpoint allow flexibility in programming.
Trend Chart records CO2 level for accurate analysis of CO2 distribution.
Adjustable Trend Chart Zoom levels let you trace your ppm levels.

【Double Outlets】Pls plug CO₂ regulator or generator into WORK1, exhaust fan into WORK2..
【Programmable】Controls the CO2(ppm) within the desired range and supports calibration and alarms.
【Plug-n-play】The CO2 controller will turn on/off the device when reaches the desired CO2(ppm) level..
【Digital Display】Both the measured CO2 and the desired CO2 are (ppm)displayed on the CO2 Controller.
【Reliable】CE&FCC certificated. S01 Sensor is suitable for home growing and HVAC Equipment..

Accurately controls CO2 levels in greenhouses or grow rooms.
Built-In light sensor that automatically turns off LEDs lights and CO2 enrichment during dark period.
Piggy back plug allows for control of CO2 generator or tank with electronic regulator.
Easiest CO2 controller to use in the industry, Controller automatically adjusts CO2 level according to altitude.

Measures CO, CO2, Dew point, wet bulb, air temperature, and relative humidity on large backlit LCD.

10-Year Battery & 10-Year Sensor: This smoke and carbon monoxide alarm provides 10 years of continuous power with a built-in lithium battery, saving on energy while remaining eco-friendly.
saves you from constantly having to change batteries.
an end-of-life signal will let you know when it's time to replace the unit for safety.
Practical LCD Display: Clearly indicates real-time carbon monoxide (CO) concentration in the surrounding air, as well as the remaining battery life and working status of the alarm.
if a CO concentration of 30-999 ppm exists for a certain time period, the screen will be backlit blue, and the LED indicator will flash red 4 times every 5.8 seconds.
2-in-1 Accurate, Reliable & Highly Sensitive Alarm: Equipped with both photoelectric smoke sensor and electrochemical CO sensor that work independently of each other.
detects both fast and slow-burning fires, and instantly notifies you when dangerous smoke or CO concentration is detected while minimizing false alarms.
provides the ultimate protection from 2 deadly threats, all contained in 1 unit.
Simple to Use: Test/Silence button enables you to test the alarm weekly, and to easily silence the alarm when false alarms occur.
