TECHNICAL SPECIFICATIONS
Wireless communication is becoming increasingly
popular in gas detection, and it is sometimes the only
way to ensure safety in existing infrastructure or remote
locations.
The OLCT 200 wireless option offers many benefits to
meet your application needs.
 900MHz
or 2.4GHz FHSS
 10mW – 1W Adjustable Tx Power
 CSA Div 1 and Div 2 Antennas
 256-bit Encryption
 Indoor Range up to 3000' (900 meters)
 Outdoor Range up to 10 miles (16 km)
 High Receiver Sensitivity
 Battery & Solar Powered Options
OLDHAM also offers a variety of wireless solutions
compatible with the OLCT 200, including wireless
controllers and solar-powered field monitors as well as
wireless repeaters and accessories.
