1. Important notice 

 

Statox 4120 is an explosion proof system for the detection of toxic gases. It can be operated in 
hazardous areas classified division 1 and 2.

  

 
Before installing and putting Statox into operation read and observe this manual! 

 
To operate the system safely, observe this manual carefully. It must be operated and maintained by 
qualified and authorised personnel. No other application than ambient air monitoring of the gas 
specified is authorised by the manufacturer.  
 

 

Safety guidelines 
 

 

Prior to connecting and installing the Statox 4120 system check if all any safety – relevant 
parameters of the system and its environment are in accordance with specifications and 
local regulations. 

 

If the Statox sensor head is installed in a potentially hazardous atmosphere the safety 
relevant parameters of the sensor head and the control module must be observed. Please 
use cable specified as recommended in this operation manual. 

 

Operating conditions must not exceed the specifications. 

 

The alarm relays of Statox 4120 are only safe to operate 24 V DC. Do not connect to mains.  

 

Maintenance work must be carried out by trained personnel only. 

 

Use exclusively original spare parts, accessories and consumables. 

 

If the safety guidelines are not observed, the Ex approval will be void! 

 
The instrument has to be inspected and serviced in regular intervals by trained personnel. For service 
or training contact your local Compur Monitors representative. The maximum maintenance interval 
should be 6 months. 
 
 
 
 
 

2. The Statox 4120 system: Purpose of use and description 

 

Compur Statox 4120 is a stationary toxic gas detection system. It monitors continuously ambient 
atmosphere indoor and outdoor. It`s integrated self test provides maximum safety of operation. 
Two user - adjustable alarm thresholds A1 und A2 can be set to any value within the measuring range. 
 
It consists of these components: 

 

Statox 4120 sensor head 

 

Statox 4120 rack 

 Statox 4120 control module 

 Diagnostic 

box

 

 
The Statox 4120 control module communicates a digital signal via a two-wire cable with the sensor 
head. It operates as power supply, alarm device and signal display. The system permanently checks 
itself for proper function and will alarm if any parameter is geting out of specifications. Sensor 
calibration and system fault diagnosis is easily achieved using the Statox portable diagnostic box.
