TrolMaster CO2 Alarm Station 2 (AS-2) for Carbon-X - Siren, LED and PPM Display

TrolMaster CO2 Alarm Station 2 With a Live PPM Readout

The AS-2 is the door-side alarm for a Carbon-X CO2 system, built to mount outside the room it watches. It pairs an audible siren with a color-coded LED indicator and an LCD that shows the live CO2 reading. Green means the room sits below 800 ppm and is safe to enter. Yellow means the level is at or above that mark, which tells anyone outside that supplemental CO2 is running. When the level passes the alarm point set in the Carbon-X main controller, the red LED blinks and the siren sounds at 100 dB. It links to the AL-1 or AL-2 sensor channel, or to both channels for full redundancy. A 16 ft RJ12 cable comes in the box for that connection. Supplemental power comes from the SPH-1 splitter hub, which the station requires. The working range is 32 to 122°F at up to 90% humidity. It ships in a 130 x 187 x 88 mm package weighing 1.26 lb. The unit is FCC and ETL registered and carries a three-year warranty.

Mounting a Carbon-X CO2 Alarm Station at Every Entry Door

Every entry door to an enriched room is a good spot for one, at eye level where staff look before reaching for the handle. The yellow state is the useful middle ground. It is not an emergency, but it tells a worker the burner or tank is active before they walk in. Set the alarm point in the main controller around your local safety guidance, not around your enrichment target. Linking both sensor channels means a single failed sensor cannot leave the door station blind. Run the RJ12 cable along the wall and through a sealed penetration, so the room stays airtight. Plan the SPH-1 into the layout from the start, because the station depends on it for power. At commissioning, lower the alarm point briefly below the room reading to confirm the siren, then set it back. The siren carries down a hallway, which is the whole point of mounting it outside. The honest limit is that it reports and alerts but does not control anything. Shutting off enrichment stays with the Carbon-X controller, so this station adds warning rather than a cut-off. Keep it indoors and away from wash-down spray.

Key Features

• Color-Coded LED Status: Green, yellow and red tell staff at a glance whether the room is safe, enriched or past its alarm point.
• LCD PPM Readout: The live CO2 reading shows on the station, so nobody needs to open the door to check.
• 100 dB Siren: The audible alarm carries through hallways when the level passes the controller setting.
• Dual-Channel Redundancy: It links to the AL-1 or AL-2 sensor channel, or both for backup.
• 16 ft RJ12 Cable Included: The cable reaches from the controller side to a station mounted at the door.
• FCC and ETL Registered: The station is registered with both bodies and carries a three-year warranty.
