Section 5: Status Leds; Operating Modes; Normal Mode - DSC LE4000 Installation Manual

5.1 Operating Modes

The LE4000 features two distinct operating modes: Normal Mode and Service Mode. The unit will be in Normal Mode when the
cover tamper is in a restored state. If a cover tamper is present, the unit will be in Service Mode.

5.2 Normal Mode

The LE4000 interface has four status LEDs. The following describes the status LEDs when the communicator is in normal operating
mode (cover and wall tampers both in a restored state).
Red This LED indicates trouble conditions.
On (solid): Trouble Requiring Service
1 Flash: Wireless Network Trouble
2 Flashes: Battery Trouble
3 Flashes: Input Power Trouble
Blue This LED indicates cellular radio activity. When this LED is on (solid), a phone line trouble condition exists. This LED
turns on when the interface switches to the wireless network (due to a landline trouble condition). This LED will also
flash once when the LE4000 transmits a signal and twice it receives a kiss-off from the central station.
Note: If the LE4000 is programmed to be the primary communicator, the blue LED remains off, but still flashes during
the signal transmission as described above.
Blue/Green This LED indicates signal strength and network technology. If the LE4000 is operating in over an LTE channel, the
(Top) LED is blue. If the LE4000 is operating over a 3G channel, the LED is GREEN.
Blue/Green Blue / Green (Top) - This LED indicates signal strength and network technology. If the LE4000 is operating on an LTE
(Bottom) channel, the LED is blue. If the LE4000 is operating on a 3G channel, the LED is Green.
If this LED is off and the Red LED is on, the wireless network service is unavailable (NO SERVICE). This LED flashes
when wireless network reception is poor. If this LED is on, the LE4000 is able to communicate with the LTE or 3G
network.
