The ServiceGuard is a combined gas proving and services isolation system and is designed to meet the requirements of IGEM/UP/11 Edition 2 for gas safety and provide complete control for the water and electric supplies. With a single key switch to enable, each service can be turned On or Off individually depending on the requirements.

With a backlit LCD, the ServiceGuard will provide a clear indication of any issues with external devices such as ventilation systems, and will provide details of gas pressures and Gas Sensor levels.

The ServiceGuard is designed to isolate all services when the room is vacant to protect the area from misuse or vandalism.

Basic Operation

Turning the key switch to ON will enable the system and each service can be switched ON or OFF, although after 30 seconds the Gas, Water or Electric buttons will need to be held for 3 seconds to enable or disable.

Upon receiving a fault signal from any external devices, the ServiceGuard will ensure that the gas is isolated to prevent any potential issues and the LCD will advise exactly what the issue is and how to rectify it.

Turning the key switch to the OFF position or pressing the panel stop button will isolate all services.

The internal Open and Display buttons are also available to aid with commissioning and fault finding, providing details of ALL interfaces at the press of a button.
