4. Installation and testing with Safera Siro
and Siro R
1. Connect all cables according to the pictures.
2. Power up the system by connecting the power supply (the system should start
normally).
3. Press the OK-button on the Sensor Unit and check the color and amount of blinks
on the light bars is correct according to these codes:
LED
Status
Remedy
One green
blink
No Connection Hub detected.
Check the cables and
system compatibility.
Two green
blinks
Connection Hub is detected and
working OK, but no CTU connection
is present.
Three green
blinks
Connection Hub is detected, and
also a CTU is connected. Everything
is working OK. If you remove the
CTU after this, an error will be
raised (two red blinks).
One violet
blink
Problem with the communication
between Sensor Unit and
Connection Hub.
This will be raised if a
Connection Hub is later
removed from the system.
Two violet
blinks
Connection Hub internal failure, for
example component defect.
The Connection Hub is
damaged and must be
replaced.
Three violet
blinks
Connection Hub has detected that
the Power Supply of the Safera
System is not working reliably or
not providing enough power for a
reliable extinguish launch.
The Power Supply must be
replaced.
One red blink
The CTU service interval (5 to 10
years) has been reached.
The CTU must be replaced.
Two red blinks Connection Hub has lost
connection with the CTU. The CTU
has been removed or the cable is
damaged.
Replace the CTU and/or
cable if necessary.
Three red
blinks
The CTU has been emptied because
of a fire alarm.
The CTU must be replaced.
OUTPUT signals
AUX1
state
AUX2
state
Safera system status
OFF
OFF
Nothing to report: no active cooking or dangerous situation
detected.
OFF
ON
Normal cooking detected.
ON
OFF
Alarm (dangerous situation detected: cooking hazard or
water leakage).
ON
ON
Alarm (fire detected and liquid extinguish triggered).
3. AUX-connection to an Automation or
Security System
The AUX signals can be interpreted in many ways:
1. Simple ON/OFF information for any type of alarm (heat, fire or water leak). This
can be read directly from AUX1 output.
2. Simple ON/OFF information for cooking activity. This can be read directly from
AUX2 output.
3. Simple ON/OFF information for fire extinguishing activity. This can be read
directly when both AUX1 and AUX2 are connected in series to the same line.
4. Four-state output according to the table below. This can be used by reading both
AUX1 and AUX2 separately into the automation system and using internal logic
to decide the state.
