TESTING THE LINKS2450 Section 5
Before testing the LINKS2450, ensure that the control panel is correctly pro-
grammed and operating properly. Refer to your system Installation Manual for
instructions on testing your system. The control panel must be programmed
properly in order for the LINKS2450 to operate.
To check that the LINKS2450 is working, apply power to the unit after all wiring
connections have been made. When the LINKS2450 is sending a transmission, the
LED on the circuit board will turn on.
5.1 Performing a LINKS Test Transmission
Contact the monitoring station to request a transmission test. Remove the tel-
ephone cord from the RJ31-X jack. Perform a Bell Test as described in the control
panel’s Installation Manual. When the test is complete, contact the monitoring
station to confirm the transmission. Perform additional test transmissions as
required by the central station.
5.2 “On Air” Indication
Whenever the LINKS unit is communicating, the LED on the unit’s circuit board will
turn ON for each round of communications. Each event has 3 rounds. Therefore, if
one reporting code is sent, the LED will activate 3 times to indicate each round.
5.3 Troubleshooting
If the LINKS2450 is not working properly, check that all wiring and all programming
is correct before calling for technical support.
