INPUT/OUTPUT ADDRESSABLE MODULE WITH SHORT CIRCUIT ISOLATOR
0 out of 5
The FG901MI series of analogue multi-modules provides supervision and monitoring for auxiliary devices on a fire detection loop. Each module can be addressed manually via a programmer or automatically by the fire control panel — including on loops with “T” connections — with input channels monitoring rest/alarm/fault conditions and output channels available as monitored or form C type.
Each module includes an integrated short-circuit isolator, ensuring communication is not interrupted in the event of a loop or device fault, for greater system reliability.
Key Features:
- Applus certified to EN54-17 / EN54-18
- Integrated short-circuit isolator on every device
- Manual or auto-addressing with auto-mapping
- Up to 240 addresses per loop
- Three-colour LED status indication
- Matt white ABS housing, extractable terminal blocks (max. 2.5mm cable)
