The Merlin1000S gas pressure proving system is designed specifically for use with School and University Laboratories.

This panel is to used to carry out a gas pressure proving test on the pipework in order to highlight if there is a gas appliance open or a gas leak. in the laboratory.

The Merlin 1000S panel is designed to give full control over the incoming gas supply with a lockable key switch operation.

The panel can work in conjunction with carbon dioxide ,natural gas, Aarbon monoxide and LPG sensors.

The panel has a built in time out facility which will automatically shut off a solenoid valve at the end of a specific time period. which can be adjusted to a 2,5 or 8 hour period. This can overridden if required.

the gas supply valve is energised.

The key operated CT500S is UK manufactured and like all S & S Northern products carries a 3 Year warranty and is fully supported by our technical team. The CT500S has a fascia
mounted emergency shut off button fitted as standard and the fascia mounted LEDs give simple and concise information to the operator.

The panel is fully compatible with S & S Northern remote emergency stop terminals allowing a large number of emergency terminals to be connected in series and wired back to the panel.

With prior notice to a fire alarm test, the operator can turn the spring loaded key to the on position giving an un-interrupted gas supply for between 10 and 45 minutes.

During this time the system controlling the gas will ignore shut-off signals from the buildings fire alarm system and allow factors such as heating systems to remain operational.
