Operating
mode
indicator
The TITANUS
RACK·SENS
®
1U operating mode indicator is continually
lit up during normal operation. The operating mode indicator flashes in
the event of data transmission for fault diagnostics in the DIAG 3 via the
infrared diagnostics interface as well as when air flow is initiated.
Indicators for *
pre- and main alarm
Each detector unit has a pre-alarm and main alarm indicator. If 2 detec-
tion units are installed, these are automatically linked together as a dou-
ble knock system ( 2 detector coincidence detection). This means that if
both indicators display main alarm, this could optionally lead to a shut-
down of external equipment, or activate the extinguishing system after a
pre-warning period.
Alarm lamp
The alarm lamp is a large-surfaced, highly visible indicator light for the
main alarm.
Sensor
indicator*
The sensor indicator consists of a vertical array of five LED indicators
(numbered from 1 to 5) and shows which sensor of the maximum of 5
connectable temperature sensors is in alarm status. You will find further
information on this in the description of the “Config/Temp” button.
Temperature indicator *
This 2-digit 7-segment indicator displays the current temperature for the
connected temperature sensors in ºC. The “Config/Temp” button enables
the current temperature readings to be shown for all sensors.
„Config / Temp“ button
The “Config / Temp” button provides dual functionality. On the one hand
it allows to eliminate ( disable ) faulty or detached bus modules such as
extinguishing-/shutdown or just shutdown modules. On the other hand
individual temperature readings of up to five connected temperature sen-
sors can be selected by this button.
Reset/ Buzzer Off
button
The
TITANUS
RACK·SENS
®
1U
device
has a reset button on the front of
the base device to reset alarm and fault indicators. This button enables
the alarm and fault signals to be reset once the cause has been elimi-
nated. The internal buzzer can also be switched off using this button.
Key-operated
switch
Off/Service/On
The key-operated switch enables the device to be turned on and off and
switched to service mode for maintenance purposes.
Network
Several TITANUS
RACK·SENS
®
1U devices can optionally be connected
to a network.
This network system enables the user to monitor status messages in all
connected TITANUS
RACK·SENS
®
1U devices. In doing so, all proc-
esses for aspects such as smoke levels, air flow values and alarm and
fault statuses are transmitted via the bus system.
The visualisation software VisuLAN-T and an associated TITANUS
RACK·SENS
®
1U network module are required to operate TITANUS
RACK·SENS
®
1U in a network and are available as an option.
