The PCX systems include the facility to send electronic signals to an Alarm Receiving Centre
(ARC), and also to send SMS text messages to mobile telephones. Alarm, etc. signals may
be transmitted via a PSTN link, using a variety of formats, to suitable receiving equipment
located at the premises of an independently operated Alarm Receiving Centre. Provision is
also made for the use of third-party device to transmit signals to an Alarm Receiving Centre
by means of the PSTN, GSM, IP or other network.
The SMS facility uses a PSTN connection to a special SMS Centre, where the information is
transferred to the GSM network for delivery to the client’s designatedmobile telephone(s).
The SMSC services are provided by GSM network operators or other reputable companies,
whose operation is outside of the control or inuence of Pyronix. PCX Control Panels
have an embedded premium rate telephone number that is used to contact a Castle host
computer prior to commissioning, in order to download the SMSC details and appropriate
call routing authorisation.
The control panel will continue to contact this PHC at regular intervals, to verify the
operation and update and conrm the routing information and authorisation as
appropriate. The charge for this service is raised by the use of the “premium rate” telephone
number. Please check with your installer for exact charges. Whilst we will use our best
endeavours to resolve any issues relating to these uses of equipment manufactured by
Pyronix are in no way responsible for the operation of the PSTN or other transmission
media, the Alarm Receiving Centre or the SMSC - or for the end-to-end security and delivery
