Description

This GS3055-I manages transmissions to a central station and can simulate the land line in the event of trouble (land line down) or even substitute the land line completely in areas where the GSM service is provided and where the land line is not available.

The GS3055-I has the capability of communicating alarm signals via the GPRS data network. The capability enables a fast reliable path to central stations equipped with a Sur-Gard System III or System

II receiver. By connecting a GS3055-I to a control panel's standard PSTN interface, telephone based

Contact ID signals are decoded and seamlessly routed through the GPRS network to any of the compatible receiver options.

The performance of the GS3055-I depends greatly on GSM Network coverage, therefore, it should not be mounted without first performing placement tests to determine the best location for reception (minimum one green LED is ON). Optional antenna kits are available.

The GS3055-I requires enrollment with CONNECT 24 to operate. Dealer application forms and additional information on the CONNECT 24 Voice Response Unit (VRU) and web user-interface can be found at www.connect24.com or at the following telephone numbers:

OPERATING PRINCIPLES

Simulated Land Line Mode

The simulated land line provides the alarm control panel (with dialler interface) with a backup line in 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: will not switch during ongoing calls

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 1second 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. The default settings are as follows:

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.

ACTIVATING THE OUTPUTS

The GS3055-I has 4 programmable outputs to activate in response to the associated events. Refer to the

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

Activating the Outputs

The GS3055-I has 4 open collector outputs capable of a maximum of 50mA. Internal events on the

GS3055-I can trigger the outputs to turn on an LED or activate an input on the host panel. The default settings are as follows:

Output is normally high and will switch to ground when the telephone line is down.

Output is normally high and will switch to ground when the GS3055-I can’t connect or communicate to the GSM network.

Output is normally high and will switch to ground when there is a problem with the power source.

Output is normally low and will switch to high when any of the previous troubles occur and/or a Failure to Communicate (FTC) trouble is detected.

NOTE: Once an output has been activated automatically, it will not restore its state until all the causes of activation are cleared.
