The GS221 addressable gas detector is designed to detect gas leaks, generate alarms accordingly, and transmit this information to the control panel.

The GS221 addressable gas detector is compatible with all Redban control panels.

It can detect all types of flammable and combustible gases.

The device detects gases such as natural gas (methane), bottled gas (propane), LPG (liquefied petroleum gas), and CNG (natural gas).

When the GS221 detects a leak while operating independently of the panel, its relay output is activated.

This allows a desired device (e.g., a gas valve) to be controlled.

The GS221 gas detector is addressed by the RB1201 address programmer, and this address information is stored in its permanent memory.
