Section 7: Troubleshooting Guide - DSC LE4000 Installation Manual

Powering up the LE4000 – when powering up the LE4000, always connect the battery (if used) first before connecting primary DC
power from the control panel or transformer.
Wiring Primary – R-1/T-1 of LE4000 to RING/TIP of control panel, DC power from control panel or DC transformer to DC input,
backup battery.
Wiring Backup – Incoming line to RING/TIP on LE4000, R-1/T-1 of LE4000 to RING/TIP of control panel, R-1/T-1 of control
panel to house phones, DC power from control panel or DC transformer to DC input, backup battery.
Testing Communications – when the LE4000 transmits a signal for the control panel, or for an internal transmission, the BLUE
light will flash one time when the signal is transmitted and two times when it gets a kiss-off.
SIM – the SIM should be activated at least 24 hours prior to installation. The LE4000 will show signal strength with an inactive SIM,
however it will display the signal strength of any available wireless network. The SIM must be active to ensure the signal strength dis-
played is that of the wireless network provider for which the SIM belongs to.
Panel Programming – the control panel should be programmed to communicate Contact ID or SIA exactly the same way it would be
programmed to communicate Contact ID or SIA over the telephone line.
