Fire Safety
The FT2010 floor repeater terminal and FT2011 floor repeater display allow for the
decentralized indication of the most important events in the fire detection system
and limited operation. Both devices can be connected to the C-NET directly as bus
users. They can be powered via the C-NET or by an external power unit. If
supplied externally, the source of voltage requires electrical isolation.
Floor repeater terminal FT2010
The following indications and operations are possible on the floor repeater
terminal:
Indication
Alarm and fault messages of connected station(s)
Activated remote transmission (RT)
Operation
Acknowledge (start investigation time)
Reset
Scroll in event lists
Deactivate buzzer
Four freely programmable keys
Floor repeater display FT2011
The following indications and operations are possible on the floor repeater
display:
Indication
Alarm and fault messages of connected station(s)
Operation
Scroll in event lists
Deactivate buzzer
Guideline
External power supply is possible with DC 24 V or AC 24 V.
Floor repeater terminals and floor repeater displays that are not fed by the
detector line (separate power supply) must be electrically isolated from the
system voltage.
NOTICE
Influencing the earth fault monitoring
Faults
Electrical isolation of the supply unit must be available for devices on the C-
NET that are fed separately. If there is no electrical isolation, the earth fault
monitoring on the C-NET is affected which may result in faults.
When an external supply unit is used, it must be taken into account that should
the external supply unit fail, the maximum current connection factor increases
significantly (line failure is possible).
When power supply is ensured via the detector line, the high maximum current
connection factor must be taken into account.
At total of up to 8 floor repeater terminals and floor repeater displays can be
connected to fire control panel FC721.
