The Merlin FAB1 is a fire alarm bypass panel designed for integration with the Merlin suite of gas safety products. It provides temporary override of gas isolation systems during fire alarm testing, ensuring that critical heating systems remain operational while testing is conducted.
By turning the bypass key switch, operators can enable uninterrupted gas supply for 10 to 45 minutes, adjustable via internal dip switches. During this bypass period, the system will ignore shut-off signals from the fire alarm system, preventing unnecessary gas isolation. However, the emergency shut-off button remains active, allowing immediate gas cut-off when required.
With a clear LED display for system indications, simple installation, and a compact design, the Merlin FAB1 is an essential solution for commercial and industrial facilities that require uninterrupted gas supply during scheduled fire alarm tests.
