WARNING
Please note the frequency converter is only one component of the TR200 system. Correct function of Fire Mode
depends on the correct design and selection of system components. Ventilation systems working in life safety appli-
cations have to be approved by the local fire Authorities.
Fire Mode operation could cause over pressure and result in damage to TR200 system and components,
hereunder dampers and air ducts. The frequency converter itself could be damaged and it may cause
damage or fire. Failure to follow recommendations could result in death or serious injury. Trane accepts
no responsibility for errors, malfunctions personal injury or any damage to the frequency converter itself
or components herein, TR200 systems and components herein or other property when the frequency
converter has been programmed for Fire Mode. In no event shall Trane be liable to the end user or any
other party for any direct or indirect, special or consequential damage or loss suffered by such party,
which has occurred due to the frequency converter being programmed and operated in Fire Mode
Background
Fire Mode is for use in critical situations, where it is imperative for the motor to keep running, regardless of the
frequency converter's normal protective functions. These could be ventilation fans in tunnels or stairwells for
instance, where continued operation of the fan facilitates safe evacuation of personnel in the event of a fire.
Some selections of Fire Mode Function cause alarms and trip conditions to be disregarded, enabling the motor
to run without interruption.
Activation
Fire Mode is activated only via Digital Input terminals. See parameter group 5-1* Digital Inputs.
Messages in display
When Fire Mode is activated, the display will show a status message "Fire Mode" and a warning "Fire Mode".
Once the Fire Mode is again deactivated, the status messages will disappear and the warning will be replaced
by the warning "Fire M Was Active". This message can only be reset by power-cycling the frequency converter
supply. If, whilst the frequency converter is active in Fire Mode, a warranty-affecting alarm (see par.24-09
Mode Alarm Handling) should occur, display will show the warning "Fire M Limits Exceeded".
Digital and relay outputs can be configured for the status messages "Fire Mode Active" and the warning "Fire
M Was Active". See parameter group5-3* and parameter group 5-4*.
"Fire M was Active" messages can also be accessed in the warning word via serial communication. (See relevant
documentation).
The status messages "Fire Mode" can be accessed via the extended status word.
