Revision 03
7.1.4 Loop test
To test the full loop there are several options:
•
Perform a full loop test by exposing the detector to a flame
•
Perform a two-part loop test using :
o
Forcing the detector outputs manually using the TLU or through HART
communication as described in §6.9.1.3 in order to test the current output or the
relay outputs
o
Using the LT15 test lamp and its associated menu (refer to §6.9.1.2 ) in order to
test the detection part
Make sure that connections to the control system or fire panel and other links to extinguishing
equipment are under control, avoiding unwanted alarms.
For any other operation, please contact your supplier or our technical services.
7.2 List of main faults
In addition of the current loop faults, other information is available from the wireless
communication tool TLU600/610 (refer to § 6.6). If the detector does not work properly, the
following table can help you to determine the causes and effects of different possible troubles
.
Symptom Possible cause Action / Check
Green LED goes out Power supply fault Check power supply voltage at power
supply and then at detector
No signal (4-20mA) Power supply fault Check power supply voltage at power
supply and then at detector
Line fault Check line continuity.
Current loop power
supply fault Check by inserting a milliamp meter into the
loop. 4 wire connections only.
No connection with
remote controller No power supply to
sensor Is the green LED blinking?
Dialogue problem Try to use the TLU on another detector to
confirm TLU operation.
UV or IR detection
fault. Detector window
contaminated Clean the detector window and test
reflectors.
(The optical self-test
has failed) Faulty sensor. If a LT15 flame test fails, then one or more
of the optical sensors are faulty. Return the
sensor cartridge to the factory
