The wall-mounted toxic gas or combustible gases detector with audio/visual alarms and relay contacts provide continuous open/enclose space monitoring. The basic unit has a detecting sensor and controller joined together. if necessary, remote sensor with explosion-proof junction box housing and 50 feet cable wire (longer length can be extended to 600 feet) connection are also available. The explosion proof sensor and housing are ideal for hazardous area monitoring and meet NEC requirements for Class I, Division I, Group A-B-C-D.  All the models can provide either 4-20mA or 0-10 VDC output for data acquisition purpose, and PLC Interfacing.  Analog meter indicates PPM or % LEL.  Digital meter use large red LED is also available. 

Each detector includes sensor and controller (R-type includes housing and 50 feet cable wire). Standard model includes meter (ppm or % LEL), LED alarm, audio alarm, fail alarm, check and test switches and relay contacts. Standard 2 stage wall mount model includes meter (ppm or % LEL), visual alarms & audio alarms (high, low), fail alarm, check & test switches and 3 relay contacts (low, high, fail).
