Commissioning of the gas monitoring system
After having the electric network complete and power voltage supplied to all devices carry out the following
operations:
assign addresses to all detectors (see details in section 7.5.1),
select the operation mode(s) (see details in section 7.5.2),
configure the control unit (see User Manual for the Teta MOD Control 1 Unit),
simulate generation of alarms signals S1 (if coupled pairs of gas detectors are included into the
system – also the S2 alarm signals) – see details in sections 7.7.3.2 and 7.7.3.3,
make sure that the system works according to the underlying logic flow chart – execute a test of
safety functions – see details in section 7.7.3.4.
If any civil engineering or building (finishing) jobs could have been performed yet after
installation of the Gas Detection System a test of all detectors is mandatory to make sure
that detectors correctly respond to presence of hazardous gases.
