Note
The Tocsin 102 Must Be Earthed, If necessary fit
a brass earthing tab washer between the locknut
and housing to bond to. Ensure the junction box,
cable and glands carry appropriate certification
for the area in which they are fitted. Cable
screens should be earthed at the control panel
and the bond checked to be <0.5 Ohms.

The Tocsin 102 series of gas detectors are ATEX approved sensors
which incorporate micro processor technology to give a stable 4-20mA
process signal output. The addressable option allows extensive
reductions in cost of installation through material and labour savings.
The in built processor can be used to pre-calibrate the sensor prior to
installation. A range of sensing technologies can be incorporated into
the housing to provide the most appropriate detection method. Available
sensor types include Infra red and Electrochemical and PID devices.

Oliver IGD offer a
comprehensive range of
control panel options
for both safe area
and ATEX operation.
Please refer to Oliver
IGD limited for further
details.
