1. INTRODUCTION

Dielro NetKeeper is a product specifically designed for security and fire-fighting installations.

All technical aspects have been meticulously analysed during development, with the aim of creating a system with the utmost quality and reliability regarding secure data transmission and concerning emergency power supply.

Its superb performance, combined with its compact form and the fact that it is easy to install and program, along with a highly-efficient after-sales service, make NetKeeper one of the most secure and reliable devices on the market.

The use of a set of copper wires, in other words, a basic (PSTN) telephone line together with (x)DSL, is likely in many cases to result in false alarms, due to the cable being disconnected from the switchboard. Even using 2 different lines.

On the other hand, where transmitters are used which incorporate GSM/GPRS and a landline (PSTN), isolating the alarm system is relatively straightforward. For instance, an inhibitor may cut off radio coverage to the system, and cut off the line, making it impossible for any calls to be made.

NetKeeper is a technologically advanced system incorporating 3 networks (TCP/IP, PSTN and GSM/GPRS) simultaneously, such that a fault in any of them is checked in a matter of seconds, and at no time does the system become ineffective.

2. WHAT NETKEEPER CAN OFFER: NetKeeper combines an innovative design with compact dimensions (194 x 93.6 x 54.3mm.), as well as high performance, thereby complying with all telecommunications, electro-magnetic compatibility and electrical safety standards: Our device features:

Up to 2 GSM/GPRS operators at the same time.

(x)DSL - TCP/IP Connection.

PSTN Connection.

Smart back-up supply management.

Analysis of a large number of settings.

NetKeeper may be used by security companies as an interface for transmitting warnings given by the installation alarm switchboard to the receiver exchange via the TCP/IP protocol, or as a transmitter. All the while, with the guarantee that it will perform monitoring of the 3 networks.

NetKeeper can also meet the needs of the client and can be used in tandem with any device specified by the receiver exchange without affecting its operation. Dielro NetKeeper can transmit the information from any installation to the software at the security company premises, in order for it to be processed on an independent computer managing incidents and logging all events that arise.

3. DESCRIPTION NetKeeper is a technologically advanced system which incorporates and monitors 3 networks (TCP/IP, PSTN and GSM/GPRS) at the same time, such that a fault in any of them is checked in a matter of seconds.

One or two of the networks could fail, but it is practically impossible for the 3 networks to simultaneously fail. Also, it should be borne in mind that the system can incorporate up to 2 different GSM operators, meaning that loss of coverage by both, together with breakage of the copper wires would only be likely where tampering were involved.

The control algorithm implemented by the Dielro NetKeeper system is distinguished by its high level of security. For this reason, in the event of all the networks going down, we can be sure that a break-in is taking place.

In addition, it provides a redundant telephone connection via the public switched telephone network (PSTN), with the possibility of automatically selecting the GSM and PSTN networks. It also provides a POTS (internal line) interface compatible with the full range of Dielro devices and with any DTMF telephone.

The device uses TRP (Transmitted Relay Process) technology, which makes it possible to connect multiple devices on its internal line using a single telephone line, without the need for additional buses and power supplies, just the set of telephones itself, covering distances of several hundred metres between devices with a simple yet secure connection.

It can be configured locally or remotely

It also enables two-way voice communication, initiated from the actual device or remotely from any telephone.

Remote operating is assisted by a voice interface, which simplifies operation with the device. In manual mode, the telephone’s own DTMF keypad is used to communicate with it, although it is possible to use a PC running Dielro software for more extensive control.

It can also act as a traditional GSM link with most telephones and private telephone exchanges.

4. FEATURES

4.1 GSM Dielro NetKeeper is compatible with GSM networks: EGSM900 and EGSM1800

The system allows the dynamic use of up to 2 SIM cards from the same or different providers. The card(s) is/are accessed from the outside, without the need to open the device.

It has a dual-band external aerial attached. The AE200-SM accessory, an external aerial with 2m of cable, can be used where coverage is low.

Page 6-6

It is fitted with an additional temperature probe for monitoring available capacity in the event of a power failure. They are also fitted with a thermostat-regulated heater to extend their operating range.

Important: Only use batteries supplied by Dielro,

6. OPERATION Dielro NetKeeper is able, via a control algorithm, to determine the communication coverage of any installation at any time.

On an ongoing basis, the device identifies all incidents concerning network coverage, whether mobile, analogue or digital.

In the central installation, the software makes it possible to determine, in real time, the status of each of the networks, as well as the most important settings in relation to each device.

Visual instructions are received for each installation regarding network availability, and it will be shown whether there is one installation (yellow), or whether there are two (orange) or three (red) networks offline. Where there are installations which cannot be communicated with (three networks down) on the alarm switchboard, an audible alarm will be activated, and this will not stop until the event is reported.

All events in relation to connectivity will be stored in a database, and historical data will be may be consulted at any time.

6.1 Voice call operation mode The device deals with three incoming calls via GSM lines(s) and processes incoming calls via a PSTN line, which are relayed directly to the internal line.

There are three types of outgoing call:

• Outgoing calls exclusively via a GSM network (non- PSTN model)

• Outgoing calls via PSTN (with backup GSM, should the PSTN line go down)

• Selection of GSM or PSTN network, handled by connected Dielro devices

• It enables sorting (according to outgoing numbers dialled) of:

Emails sent.

SMS messages sent.

IP packets sent.

Instructions sent via the serial port.

Should the device lose coverage, have no batteries or other eventualities occur, the PSTN line is used to make emergency calls.
