with the "key" button. Then the unit will display “To" and while "????” is being
displayed, enter the value of the end of the search range (0 to 255) - confirm with
the "key" button. One/two-digit values entered must be confirmed with the "key"
button, while three-digit values will be saved automatically (press the "#" key to
exit the function). Then the unit will start searching for receivers by displaying
successive addresses from the pre-set range. If a misplaced or damaged
receiver is found, the unit will stop searching with this address and will signal it
with a beep. When the "key" button, the unit will start searching for new receivers.
When the "#" button is pressed, the search is ended and the unit returns to the
installer’s menu.
The function only works for receivers with handsets and may not be available
when using other manufacturers’ receivers. P19 function is an additional receiver
test.
P19 LINE TESTING
LTest
This function is used to check whether or not the receivers cause any interference
in the system (for instance when selecting addresses). The program will find
potential receivers with faulty address switching or decoding system.
This function is only available for "Master" panels (or "Slave" panels where the
"ML" terminal is not connected). In operating mode with 4 zone switch ("SW4S-
DIN") the function is not available.
Upon activating the function, the unit will display “LTest”; all receivers will be reset
and a test signal will be generated in the line. Each faulty receiver should receive
the test signal - to find those faulty receivers, one needs to walk around the
building and identify those apartments, where the test signal is received. If the
unit also displays "LineEr", it indicates that one or more receivers are actually
faulty. Faulty receivers should be disconnected from the system as they may
cause the whole system to malfunction. If the system works as intended, no faulty
receiver is detected during the test, and the unit should display "LTest". Use the
"#" button to turn the test off.
Enable the P18 function for further testing of the installation.
