The Tocsin 102 and 103 series Pellistors are flammable gas detectors based on well proven catalytic
principles. The units can be used either as conventional 3 wire 4-20mA transmitters or as 4 wire
addressable modules capable of integration onto an IGD data highway. Either option allows integration with
Tocsin 625, 700 and 920 series control panels.

Pellistors are capable of detecting all flammable gases but are usually made sensitive to the particular
target gas during calibration. It is therefore important that detectors are correctly installed and calibrated for
correct operation.

Siting of the detector should also be carefully considered to take into account air flows, site geometry and
the characteristics of the target gas. This instruction manual is intended fo ruse by competent persons who
can either demonstrate previous experience and training with gas detection systems or have completed
training courses at Oliver IGD Limited. Performance of the system will be a function of how well the system
is installed and calibrated.

Oliver IGD Limited can help advise on the correct siting and calibration of gas detectors.
