Installing the Gas Transmitter
10
Commissioning
The Dräger PIR 3000 infrared gas transmitter is preconfigured and ready for use
after installation.
 Deactivate the alarm call to the central device to avoid false alarms.
 When the supply voltage is applied, the gas transmitter automatically performs
a self check (10 seconds), then automatically uses the factory-preset calibration
(see page 11) and gas category.
For the duration of the self test, a signal of 1 mA is issued.
 Wait for the running-in period of one minute to expire. No settings can be
changed at the gas transmitter during this period. The gas transmitter will emit a
1 mA signal for the duration of the running-in period.
 Check signal transmission and adjust if required (see "Checking the signal
transmission, checking the alarm trigger and displaying the gas category" on
page 17).
 Check setting of the gas category for the intended use. If required, set the gas
category (see "Changing the gas category " on page 18).
 Check the calibration of the gas warning system (see "Calibration" on page 11).
 Reactivate the alarm call to put the system back to normal operating state.
NOTICE
To prevent moisture condensation on the optic surfaces of the device, parts of the
transmitter housing are heated from the inside. This can increase the
surface temperature by approx. 5
o
C.
