Fixed Gas Detection System
Wired & WireFree™



home otis instruments fixed point detectors Accessories Otis Instruments Fixed System Accessories




Otis Instruments fixed gas detection systems are designed to provide continuous monitoring for a variety of common atmospheric hazards including oxygen deficiency and/or enrichment, combustible gases and vapors, and specific toxic contaminants such as:

Ammonia (NH3) Formaldehyde (CH2O) Oxygen (O2)
Carbon monoxide (CO) Hydrogen Cyanide (HCN) Ozone (O2)
Chlorine (Cl2) Hydrogen Fluoride (HF) Sulfur dioxide (SO2)
Combustible gas (LEL) Hydrogen Sulfide (H2S) Phosphine (PH3)
Fluorine (F2) Nitrogen Dioxide (NO2) PID sensor for VOC detection and many others

The ability to display data and activate alarms in response to readings sent from remote on-site sensors make the Otis Instruments controllers an efficient way to monitor toxic gas hazards.  System configurations can include radios for WireFree™ communication.  With the addition of dry contact relays, signals can also be routed to and from other remote sensors such as temperature, pressure, tank levels as well as triggering lights, horns, alarms and fans.

Accessories for these systems include, alarm lights, horns, and kits for remoting sensors up to 250' from the controller.  Ongoing system maintenance will require calibration and replacement sensors.
