INSTALLATION

Mount the transmitter securely on a wall using accessories (screws and dowels) appropriate for the mounting surface.
The part of the transmitter cover with the top ledge should be facing upward so as to protect the sensor from dust.
About the precautions to achieve a good functional behavior of the device, it is important to note that the transmitters placement in the controlled environment, it is important to check:

• Possible openings in walls and ceilings and air currents
• Composition and shape of the environment
• Extent of the area to be protected
• The accessibility required for maintenance.
• Gas density (heavier or lighter than air)
• Gas emission rate (flow)

The response time of the sensor is closely related to its position in the environment and the type of gas to be detected.
For gases to be detected, it is necessary to assess their relative density to air and position the transmitter accordingly.

GENERAL PROCEDURE FOR CALIBRATION IN GAS

WARNING

• The transmitter must NOT be in an alarm or fault condition.

• Be aware of any alarms or faults BEFORE starting the Calibration/Bump test procedure.

• At altitudes above 6,560 ft (2,000 m), calibration will result in a lower reading.
  Refer to the user’s manual for more information.

• Calibration or Bump test procedure can be performed out:
  – Via the Seitron Guard App – follow the boxes “ “.
  – On the transmitter using the magnetic switches-follow the boxes “ “.

• If the calibration procedure or Bump test is performed via the Seitron Guard App, all outputs are automatically deactivated.

• If the calibration procedure or Bump test is performed from transmitter, Bluetooth® must be turned off.

• For Span calibration and Bump test from transmitter, make sure you have entered the value of gas concentration to be used in the menus “Configuration -> Calib. Manual Gas -> Span Concentration” and “Configuration -> Manual Bump-> Threshold” found in the Seitron Guard App.

• If the Bump test is performed by transmitter, the outputs can be enabled according to the configuration set on the Seitron Guard App at the “Configuration -> Manual Bump -> Enable Alarm” menu.

THE FOLLOWING TOOLS AND EQUIPMENT ARE NEEDED TO PERFORM THE CALIBRATION OR BUMP TEST:

• Mixture for Zero calibration gas With the exception of CO2 and O2 sensors, ambient air may be used instead of Zero gas if the area where the transmitter is installed is devoid of the gas to be detected or any other gas to which the sensor may be cross-sensitive.
  For CO2 and O2 sensors, use air-free nitrogen as the Zero gas; the cylinder must be equipped with a pressure regulator with a flow rate of 0.5 l/min.

• Mixture for Span gas calibration or Bump Test execution.
  Mixture of titrated gas suitable for the sensor to be checked with known gas concentration such as to trigger the alarm at the set threshold; the cylinder shall be equipped with a pressure regulator with a flow rate of 0,5 l/min.
  For CO2 and O2 sensors, the Span gas shall be in nitrogen equilibrium (N2); for all other sensors the Span gas shall be in air equilibrium.

• Calibration kit ACKC01 (including magnet); mount the calibration adapter on the lid of the gas detector.

• Flowmeter.

• Pipe with “T” derivation for connecting the cylinder to the instrument and flow meter.
