Commissioning

Merlin sensors are designed to operate in a wide range of harsh environments and conditions. However, it is

important that exposure to high concentrations of solvent vapours is avoided, both during storage and operation.

We recommend all Merlin gas detection equipment be commissioned by competent/trained engineers to

ensure correct installation and operation. This will ensure the safety equipment performs as intended and

free from unforeseen damage caused by transit and handling/installation etc.

Merlin gas detectors are factory calibrated when shipped under ambient conditions, however, we strongly

recommend the detectors response and alarm signals are tested and validated once installed and

subsequently every 6-18 months thereafter to retain optimum safety.

During Commissioning

Check installation, mounting, cable entry, position.

•

Check the power supply voltage and indicator.

•

Check/perform calibration.

•

Check indications for proper operation.

•

Check buzzer and relay operation.

•

Check signal transmission to the BMS/central controller, where appropriate.

•

Regular maintenance and calibration of the sensors by trained technicians is strongly recommended.

Inspections and services must be documented and executed at regular intervals.

The frequency must be determined and observed by the person responsible for the gas warning system

according to all regulatory, code and legal requirements. The inspection interval is normally 6 to 18 months to

retain optimum safety. The date for the next maintenance must be affixed to the equipment sensor.
