• While the alarm window is active, any scheduled normal mobile or fixed network BUP messages

are not transmitted.

• If an acknowledgment is received, the GasGate RD returns to its normal BUP transmission

schedule. The normal mobile and fixed network BUP messages will contain the appropriate

tamper flags set in the message.

• If an acknowledgment is not received by the GasGate RD, the device returns to its normal BUP

transmission schedule. The GasGate RD transmits normal mobile BUP messages with the

appropriate alarm tampers flags set. When a fixed network BUP event is triggered, the GasGate

RD enters the alarm state and repeats the alarm BUP message transmission until an

acknowledgment is received by the network.

• Alarm ID defining the cause of the alarm

• Endpoint ID

Operational States

The GasGate RD normal operational states include:

• Closed. The GasGate remote-controlled valve receives a command to close from a handheld, mobile, or

fixed network reading device. When the GasGate valve is closed, the flow of gas stops.

• Open. The GasGate valve receives a command to open from a handheld, mobile, or Fixed Network

reading device. Opening the GasGate valve requires an onsite visit to physically open the valve. First, the

technician uses the handheld device to issue the connection (open) command. After the connection

command is received, the onsite technician uses the GasGate valve tool to open the GasGate valve. After

gas flow begins, the technician ensures the system is working correctly and gas is flowing in the system.
