Settings According To Local Requirements; Forcing An Alarm Message Manually - alphatronics PSTN-2-IP Installation Manual

The IP (+ GPRS) transceiver can be set-up and configured via a web interface. The set-up and configuration
is explained in the following pages.
The AlphaCom PSTN-2-IP GPRS is technically the same as the AlphaCom PSTN-2-IP but has a built-in GSM
module to transmit messages via the GPRS network to a monitoring station. In the GPRS variant the back-
up connection for both Transceiver 1 and Transceiver 2 can be set to GPRS.
The AlphaVision IP transceiver is technically the same as the AlphaCom PSTN-2-IP and is delivered in a
synthetic casing. The AlphaVision IP + GPRS can be used as a plug-on board for Alphatronics control panels.
The AlphaVision IP transceiver does not have a PSTN input but only contains a RS-485 bus connection.
The Alpha Vision IP + GPRS transceiver is technically the same as the PSTN-2-IP GPRS but as loose prints
plug supplied for Alphatronics plants and does not have a PSTN input but only on an RS-485 bus connector.
In this manual all programming examples are shown using a PSTN-2-IP GPRS transceiver. All other variants
have the same firmware kernel but differ in terms of hardware and software functionality.

SETTINGS ACCORDING TO LOCAL REQUIREMENTS

The PSTN-2-IP (GPRS) transceiver and AlphaVision IP (+ GPRS) can be used in various applications. In
installations were local or European regulations apply (for instance EN50136-1-1 and EN50136-2-1) we
strongly advise to take the following into consideration:
Access to the web interface must be secured with a username and password. The password chosen must
not be a simple and easy password and it is advised to always use a combination of digits and letters.
After installing and programming the IP (+ GPRS) transceiver dipswitch 3 must be set to OFF to make it
impossible to access the web interface remotely. See page for an overview of dipswitch settings.

The IP (+ GPRS) transceiver must be placed in a casing which complies with regulations and the security
class specified by local regulations. The AlphaCom PSTN-2-IP and AlphaVision IP do not include a GPRS
option and can therefore not be installed in installations requiring grade 4. In these situations a PSTN-2-IP
GPRS or AlphaCom XL GPRS can be used.
When installing a PSTN-2-IP (GPRS) the PSTN tamper loop should be enabled. If the connection between
the analog dialer of the security alarm system and the PSTN interface (CMK) is tampered the PSTN-2-IP
(GPRS) itself will create a tamper message.
On the PSTN-2-IP (GPRS) the PSTN priority switch will ensure that the control panel detects the
disappearance of the analog telephone line if the IP (and GPRS) connection for transceiver 1 or 2 fails or
disappears. When using a PSTN-2-IP GPRS the transceiver will first try to establish a connection (if set) via
GPRS to the monitoring station, if this fails the priority switch will be activated.

Forcing an alarm message manually

According to the 50136-2-1 is must be possible to create an alarm message manually. When using the IP (+
GPRS) transceiver the analog dialer of the control panel is connected to the PSTN input (CMK). If the dialler
or control panel has the possibility of forcing an alarm message manually, the IP (+ GPRS) transceiver
complies with the regulations.
In all other cases it is advised to program the tamper switch on the IP (+ GPRS) transceiver to cause an
alarm when it is opened.
