OPERATING PRINCIPLES

Simulated Land Line Mode

The simulated land line provides the alarm control panel (with dialler interface) with a backup line in the

event of PSTN line trouble. If the voltage on the land line terminals (

TIP/RNGTIP/RNG

TIP/RNG) drops below 4V for a

period of between 10 to 45 seconds (depending on the device connected to the

T1/R1T1/R1

T1/R1

terminals), the

GS3055-I will switch the connected telephone device to the GSM Network for a full 15 minute interval,

at the end of this interval, it will check the land line:

•

if the land line has been restored if the land line has been restored

if the land line has been restored, it will switch the connected device back to the land line;

•

if the land line is still downif the land line is still down

if the land line is still down, it will continue to simulate the land line until it is restored. The GS3055-I

will not switch during ongoing calls

NOTE: When the land line is down, the GS3055-I will provide a dial tone to any device connected

to T1 and R1, including any telephones on the premises. However, the premise phones will not be

able to dial out over the GS3055-I.

Sequence

• When alarm is triggered, the Alarm Panel goes off-hook

• The GS3055-I will assert dial tone

• Control Panel dials the number of the central station. Ensure the alarm panel inserts a minimum 1-

second pause, or has dial tone search enabled before dialing the number

• The GS3055-I detects the DTMF dialing and stops dial tone

NOTE: The GS3055-I is unable to decode pulse dialing.

• The GS3055-I will send the required Contact ID dual tone handshake to the panel

• After receiving the handshake, panel transmits alarm message in Contact ID format

• The GS3055-I decodes and transforms Contact ID digits into the IP packet and sends it to the Central

Station Receiver over the GPRS network

• The receiver acknowledges the alarm and sends command to the GS3055-I to generate the

corresponding 1400Hz kiss-off signal for 800ms minimum

• After the GS3055-I generates kiss-off, the panel goes on-hook if no more alarms need to be sent, or

it can send the next alarm

Inputs

The GS3055-I has 4 inputs that can be used to trigger specific communications. These events will transmit

using Contact ID format with Input 1-4 reporting as [991] to [994] respectively. Default settings below:

INPUT 1- FIRE INPUT 3 - BURGLARY

INPUT 2 - PANIC ALARM INPUT 4 - SYSTEM TROUBLE

These inputs are normally open and will activate when a short condition is detected between the terminal

and the COM. Refer to the GS3055-I Wiring Diagram (Figure 2) at the back of this manual.

NOTE: When the GS3055-I is configured in Land Line Mode, these inputs should be restricted to

monitoring of trouble conditions.

NOTE: These inputs communicate using Contact ID format.

NOTE: For UL/ULC installations, connections between alarm panel outputs and GS3055-I inputs

shall be run in mechanical protective conduits. To reduce interference with the antenna, it is

recommended that the metal conduit is not connected to the knock-outs on the top of the cabinet.
