Remote Oxygen Depletion Safety Alarm
The Remote Oxygen Depletion Safety Alarm is designed to protect customers and workers near stored inert gases like Nitrogen, Argon, and others. Low oxygen alarms are critical in cryogenics, cryotherapy, food production facilities, process cooling, or in any enclosed space where inert gases are stored.
- Wired O2 Monitor & Remote Display
- Measures O2 concentrations from 0-25%
- User configurable for specific applications
The Monitor has both audible and visual alarms. 3 built-in relays are triggered at 19%, 17%, and 15% respectively that can control an exhaust fan or send an alarm to the fire department or monitoring company. The alarm levels are user configurable to allow for specific applications.
The Oxygen Depletion Safety Alarm is easy to install and use. Simply mount both units on the wall (all cables and hardware included), plug the monitoring unit into a standard wall outlet, and the alarms are ready to protect your customers and employees.

Accessories
CM-1026 - Dual Strobe Add On Kit. Attach a flashing strobe to both the Sensor Unit and the Remote Display Unit to give a more visual alarm. Great for high-noise environments. Some local fire codes also require this. Call to see if your local municipality requires these.6
CM-0126-5, 6 - Strobe Tower Add On Kit. The Strobe tower gives a visual indicator of which of the 3 alarms were triggered as well as providing a louder alarm. Both 110-224VAC and 24VDC models available. Order online here.
RAD-0022 - Additional Remote Display. The Sensor display unit comes with one remote display that can be placed up to 300ft. away using Cat5 or greater Ethernet cable (28ft. included in box). Purchase one or two additional remote displays, then daisy-chain them so long as the total run is less than 300 ft.
