Firmware Versions
Texecom Monitor enforces the use of:
• Premier Elite > V6.01.xx
• SmartCom or SmartCom > 4G V4.01.00
Product shipped from the factory after the 1st April 2022 will be fitted with a compatible version, but the service always encourages
the use of the latest released firmware version.
Premier Elite V5 systems can be upgraded directly and remotely from the Texecom cloud, earlier versions will require a field visit and
the use of the Premier Elite flasher software and cable connected to a PC to facilitate upgrade.
SmartCom product earlier than V2.02 is not compatible with connection to the Cloud service but can be returned to the factory for
upgrade.
Technical information on the service provision
The SPT device operates in a “Store and Forward” mode of acknowledgement.
Substitution and Information Security (RE: EN 50136-2 clauses 6.3 & 6.4)
In order to achieve the related requirements of EN 50136-1 clause 6.8.2 for substitution security, the following method is used on the
provided system:
• Requires a UDL password and a App Code Request to set up the SmartCom and to register the site with TCS / link to
existing site on TCS.
• Prevents one SmartCom being substituted with another by checking the GUID is as expected and rejecting any
communications from a SmartCom without a matching GUID
• The authenticated password for the cloud(SPT) is 16 characters along with a user id that is a 32 character v4 GUID
In order to achieve the related requirements of EN 50136-1 clause 6.8.3 for information security, the following method is used on the
provided system:
Encryption Method
• TLS 1.2 / RCS / AES.
• Dependent on Path; AES on incoming 4G and TLS on all other Paths.
• 128-bit encryption for all paths.
• Encrypted at Smartcom, Encrypted from Cloud to ARC using protocol.
• All data communication between Smartcom and TCS are encrypted.
• Encryption keys are machine generated and randomised.
• These are handled by SSL certificates and are changed every 12 months.
The above prevents unauthorised reading of the transmitted information.
In order to detect unauthorised modification of the information transmitted a signed message is used which employs both a public
and private key.
Availability Monitoring
Texecom monitor the availability of the Texecom Monitor service by using analytical tools to determine its compliance to EN50136-
1 Table 2 for the appropriate grading. This is determined by using a calculation of live systems every 31 days with a maximum of
1000 events. The transmission time from the SmartCom to the Monitor Cloud is measured on each event and recorded within the
database. The average transmission time and 95th percentile is calculated in seconds. This is validated against the grading category
criteria in the standard to ensure continuing compliance.
We are monitoring the cloud via an external service which monitors the system in multiple different ways every minute. The results
of this are recorded in a database and any errors are alerted to the on call team member with full escalation policies.
Texecom uses the Texecom Cloud and Monitor services data recorded from the panel events to the system along with the external
monitoring system to calculate the availability of the system as a whole.
A summary report is available on request in the form of a PDF report for inspection.
