1  General Description 
023-064X series gas detectors are versatile, self-contained gas sensor monitors, used for automated 
ventilation control 
and/or 
warning systems. They can easily be networked together, with 
or 
without a 
central controller into 
groups.
 
1.1  Applications: 
•  Vehicle Emissions 
•  Combustible Gases 
•  Refrigerant Gas Leak Detection 
•  Industrial Health and Safety 
1.2  Features: 
•  Stand-alone operation with 1 adjustable alarm relay, indicators and strobe 
•  BACnet Laboratory (BTL) listed Smart Sensor, up to 76,800 baud 
•  BACnet MS/TP RS485 interface 
•  CAN network interface for master-slave operation or central control via a controller. 
•  Pre-calibrated plug-and-play sensor modules avoid the need to recalibrate when upgrading expired 
sensors. 
•  Impact resistant, water resistant enclosure, with top 
wir
e 
entry and drip proof wire guide.
