To connect the DCT-1E to an MXL system, you must provide 24 VDC power from the panel and use contact closures to trigger the communicator's five channel inputs (Page 1) [1].
Power Connection: Connect the DCT-1E color-coded flying leads to a 24 VDC output on the MXL panel (Page 2) [1].
Channel Wiring: Wire the MXL's alarm, supervisory, or trouble relays to the DCT-1E's five supervised inputs. The MXL must use contact closures for these connections (Page 1) [1].
AC Monitoring: Program a relay on the MXL as AC Fail and connect it to the DCT-1E AC monitoring input to report power loss (Page 2) [1].
Telephone Lines: Install and connect two RJ31X jacks to the dual phone line interface for central station communication (Page 2) [1].
Programming: Attach a DCT-P local programmer to the plug-in connection point to configure account information, phone numbers, and reporting formats like Contact ID or SIA (Page 2) [1].
