System Overview

1. The VisorALARM PLUS 2U receiver

The IP VisorALARM PLUS 2U receiver (Model VisorALARM PLUS 2U) is a communications device developed by Teldat for security environments. The IP VisorALARM PLUS 2U receiver’s principal task is to receive alarms over an IP network and to subsequently send them to an automation software (SwAut). The functionality of the Teldat VisorALARM PLUS 2U is similar to any other alarm receiver which receives alarms over the telephone line. If the automation software fails or isn’t present, VisorALARM PLUS 2U is able to acoustically signal the reception of new signals. It also provides specific function keys to manually acknowledge every received signal.
The IP VisorALARM PLUS 2U receiver operates together with the IP Module (mIP/IPDACT), which receives the alarms from the alarm control panels and sends them to the Teldat VisorALARM PLUS 2U over an IP network. Additionally, the Teldat VisorALARM PLUS 2U monitors connectivity with all the registered mIP/IPDACTs. Should connection fail, then the VisorALARM PLUS 2U generates alarms for the SwAut.
The VisorALARM PLUS 2U IP receiver has the high availability feature added, which permits a mIP/IPDACT the possibility of IP backup towards another backup center made up of various VisorALARM PLUS 2U receivers.

2. The IP modules (mIP/IPDACTs)

The IP Modules (mIP/IPDACTs) connected to the client control panel carry out two tasks:
1. Capture the alarms sent by the control panel and send them over the IP network to which they
are connected. These alarms are then received by the Teldat VisorALARM PLUS 2U in order to be sent to the corresponding automation software (SwAut).
2. Generate monitoring traffic so that both ends of the security environment check the IP
connectivity, permitting the above task to be accomplished.
The mIP/IPDACT is a device that intercepts the control panel telephone connection with two aims: firstly to detect when the panel sends an alarm in order to capture and retransmit it over the connected IP network and secondly to allow the telephone line to be used at the same time as sending alarms.
The interception of the telephone line takes place ONLY in cases where connectivity with the Teldat VisorALARM PLUS 2U has been verified. The mIP/IPDACT - VisorALARM PLUS 2U connectivity is checked through a traffic monitor which the mIP/IPDACT periodically sends and to which the Teldat VisorALARM PLUS 2U responds. If this exchange of messages does not occur during the configured time, the mIP/IPDACT tries to resend. If after a configurable number of attempts (between 1 and 9), a satisfactory response is not received, the connectivity is presumed lost. The time between polling messages is programmable between 0 and 90 seconds, a typical value being 15 seconds. The time between retries is also configurable, between 3 and 9 seconds.
If a network backup scheme is running, the mIP/IPDACT has a second IP receiver to establish communications and send alarms. If this second receiver does not respond to the communication established with it by the mIP/IPDACT (again after a configurable number of attempts), the telephone line access is returned to the control panel as if the mIP/IPDACT was no longer operative at the alarm level. From this point on, the mIP/IPDACT will try to re-establish communications with both the main Teldat VisorALARM PLUS 2U as well as the backup, if there is one. As soon as this is re­established with either of the VisorALARM PLUS 2U, the mIP/IPDACT will intercept the telephone line once more.
The monitoring traffic is encrypted UDP traffic. The Ethernet frame size does not exceed 70 bytes. The monitoring interval, the number of retries and time between retries are all configurable, both for the main VisorALARM PLUS 2U as well as for the backup. The time between retries is an important parameter as it influences the global traffic supported by the VisorALARM PLUS 2U (polling over all the devices). You also need to bear in mind that polling is a tool to control the state of both the alarm reception center and the mIP/IPDACT. A long interval between polls can lead to situations where the VisorALARM PLUS 2U delays detecting a problem with the mIP/IPDACT and consequently a problem with a customer. Finally, if the mIP/IPDACT accesses the Internet via a device which executes NAT, traffic coming from the VisorALARM PLUS 2U (configuration for example) will not reach the mIP/IPDACT if the period between polls is inferior to the outgoing router NAT tables refresh time (a typical refresh value is 5 minutes).
The Teldat VisorALARM PLUS 2U receives monitoring messages from the mIP/IPDACTs. If these are registered, they are assumed alive and an acknowledgement response is sent to them; if the mIP/IPDACTs are not registered, they are ignored. Periodically the status of all the registered mIP/IPDACTs is checked and an alarm is generated for all those which have not notified their availability (i.e. those which have not responded since the last check). This is a 350 code alarm from the Contact-ID protocol (Communication trouble) which is received in the SwAut. Default is 350. As each mIP/IPDACT can have a different polling time with the center, the VisorALARM PLUS 2U checks the status of each mIP/IPDACT according to the polling time value for each of them.
In order to prevent the Teldat VisorALARM PLUS 2U from sending hundreds or thousands of communication failure alarms when faced with a situation of general failure of IP traffic reception, the device itself monitors the network access through ICMP echo packets (ping) to a known address: if the

echo packets towards this address fail then a code 356 alarm is generated from the Contact-ID protocol (Loss of central polling). Default is 356.
In order to simplify installation and updating of the registered mIP/IPDACTs, the IP VisorALARM PLUS 2U receiver has additional facilities.
To install new mIP/IPDACTs, the Teldat VisorALARM PLUS 2U holds configuration patterns associated to installer passwords. These permit you to automatically register new mIP/IPDACTs in the supported mIP/IPDACT list and at the same time enable the mIP/IPDACT to request the necessary configuration for start up. The device can simultaneously have multiple patterns; the choice of one or other depends on the installer password used in the mIP/IPDACT to request the service.
In order to maintain and update the registered mIP/IPDACTs base, the Teldat VisorALARM PLUS 2U has commands available to remotely update one or multiple configuration parameters used by the mIP/IPDACTs.

3. Management and Monitoring

The IP VisorALARM PLUS 2U receiver can be managed and configured through a local console and also remotely (telnet). In both cases, the access is restricted to users who are identified by a user na me and a password. Also the receiver can be monitored through a local console, remotely through telnet and from the receiver’s keypad and LCD display.
The configuration is displayed in text mode, consequently edition and support in other platforms is simpler and more comfortable.
