2. User Interface
The HMI is the user interface to the smoke shaft system and provides system information and functions
including:
•Alarms, faults, and events
•System reset
•Diagnostics and maintenance features
The HMI should be located at the firefighter’s entrance or command location to provide alarm status for
firefighters and easy operation and access for maintenance activities.
The HMI is a colour touch screen is in landscape style. The touch screen is resistive type and operating the
screen can be done by finger touch or by a stylus or pointer.
A USB flash memory module is inserted at the back of the HMI for storing event logs and backup files. To
access the module, remove the screw located at the bottom of the bezel then open the hinged fascia door.
DANGER:
Risk of electrocution. Observe electrical safety procedures and check power supply has
been isolated or disconnected safely before removing panel covers.
