GR-Type Repeater Panel
Standard Type
Model: T4G-40
The GR-type repeater panel relays event information such as fire alarms, supervisory signals, and faults from all connected addressable devices to the GR-type fire alarm control panel. It also receives control signals from the control panel and operates connected equipment through repeater modules and other interface devices.
When a single GR-type combination fire alarm control panel cannot cover the entire facility due to limitations in circuit capacity or wiring distance, additional repeater panels can be installed to build a wider fire monitoring and control system.
- Features
-
· Fast response speed equivalent to the control panel (RS-485 communication) · Can operate independently without a fire alarm control panel · M-NET RS-485 Loop Back and P-NET PLC Communication Loop Back · Isolator support for system line short-circuit protection (Repeater Type / Isolator Type)
