Blue LED in normal mode

In normal mode, the blue LED indicates cellular radio activity. The blue LED turns on when the
interface switches to the wireless network. The following table describes the statuses that the
number of flashes represent.

Note: If you program the 3G4000W to be the primary communicator, the blue LED remains off
but flashes during the signal transmission above.

Operating Principles

Simulated landline mode

The simulated landline provides the alarm control panel with a back-up if there is PSTN line trouble.
Depending on the device that connects to the T1/R1 terminals, if the voltage on the TIP/RNG
landline terminals drop below 2.8V for a period of between 10 and 45 seconds, the 3G4000W
switches the connected telephone device to the wireless network. After 30 to 40 seconds, the
system checks the landline for one of the following conditions:
• Landline restored: If the landline is restored, the 3G4000W switches the connected device back to
the landline.
• Landline not restored: If the landline is not restored, the 3G4000W continues the simulation until
the landline is restored
Note: The 3G4000W does not switch the connected telephone device to the wireless
network during ongoing calls.
When the landline is down, the 3G4000W provides a dial tone to any device that is connected to the
T1 and R1 terminals. This includes any phones on the premises. The phones on the premises cannot
dial out over the 3G4000W.

Panel transmission monitoring

The 3G4000W uses panel transmission monitoring (PTM) to monitor the panel's attempts to
communicate with the central station. If the panel cannot communicate over the landline, the
3G4000W switches to the wireless network.
Note: PTM is an addition to the regular line voltage detection, and is active only when you
configure the 3G4000W as a back-up communicator.
The 3G4000W monitors the phone line for four consecutive failed attempts within a 12 minute
timeframe. The dialed panel phone number must include five or more digits for the 3G4000W to
detect the dialing attempt. The system assumes that a failed dialing attempt occurs if a line seizure
