The TCOD-IR should be mounted in a suitable position, eg on a wall, with the opening of the
transmitter pointing downwards. Allow a 10 cm gap between the head of the transmitter and any
other object for calibration.
Some space should also be allocated for cable insertion which is from the right-hand side. The
connecting cable should be placed above the transmitter to leave the opening of the sensor element
freely accessible.
THE TRANSMITTER MUST NOT BE CONNECTED WITH REVERSED POLARITY. THE
ELECTRONICS CAN BE IRREPARABLY DAMAGED.
If the voltage input is already connected when power is supplied to the gas detection unit, the output
current may momentarily rise to 32 mA.
Alarm signals at the gas detection unit should be reset.

Two minutes after power has been supplied, the transmitter is ready for operation.
For accurate calibration allow up to approx. 15 mins. for the sensor electronics to stabilise.
