8.2 Loops (Control Panel CM2.2)
8.2.1 Central status
CAUTION!
The presence of an authorised engineer is required before power is connected to the
central unit.
•
All control and indication functions must be connected to relay outputs.
Connect all outputs and inputs according to the terminal drawings.
•
Connect finalized loops to the central according to the terminal drawings.
NOTE!
Deviations from the above criteria may cause time delays.
8.2.2 Verification of Loops
CAUTION!
Be sure to remove protective covers from all installed detectors before the fire
detection system is put into operation.
CAUTION!
If a loop unit is removed it has to be replaced as soon as possible in order to secure
the functionality of the fire detection system.
The verification procedure is described below:
1 Make sure that the system is connected to an
external power supply.
Refer to the Installation chapter, for
information on the electrical
connections.
2 Connect both the A- and B-side of one of the
loops to the CS-Loop M module.
Connect batteries if applicable.
NOTE!
Installations in hazardous
(Ex-classified)
location/areas shall be
commissioned and tested
with the cable as a
branch/spur before making it
into a loop.
3 Power up the system.
The Power LED lights and a text appears on the
display to show that the system is up and
running.
Wait for a few minutes to let the system perform
all system checks.
If the system detects a fault during the start-up,
a fault code is displayed in the control panel.
For more information about the fault
codes, see the Fault code list.
4 Measure the voltage on the A-side in the central
unit. If all loop units are connected correctly (no
polarity fault), the voltage range loop should be
30-37 VDC.
If this is not the case, check the fault
list.
