5 Testing

1. Configure the control panel for communication routes.

Refer to your control panel’s documentation for programming instructions.

2. Send a test alarm using the configured route(s), and verify receipt of the alarm at the

central station.

3. If incoming GSM calling is enabled, initiate a phone call to the control panel.

5.1 GSM Trouble Indication

The ITS-DX4020-G module activates the phone voltage after GSM registration finishes. The

module removes the phone voltage if it detects a communication problem when being used in

PSTN (Contact ID) Over GSM Mode. If all trouble conditions restore, the phone voltage is

automatically reapplied. This allows legacy control panels with phone line voltage monitors to

support the module and display communication trouble signals. The removal and restoral of

the phone voltage from a trouble condition is controlled by the trouble reporting delay time

parameter.

The following conditions cause the phone voltage to be removed:

– SIM missing

– Low signal strength

– Not able to register on the GSM network

5.2 Firmware Version

Use the LED DIS function to determine the firmware version of the ITS-DX4020-G module

without a USB connection. When you first install the LED Disable jumper, the LED flashes the

firmware version as a series of three flashes (for example, 1 - 4 - 3 flashes signifies

firmware version 1.4.3).
