applicable.
1 - The Emizon TCD should be placed in EN-compliant /installation/housing, related
to the grade/security levels.
2 - In order to use the Emizon service and obtain support services, an authorized
person with level 2 access as defined in EN50136-1:2012 should grant Emizon
access at level 4.
3 - The compliance with EN50136-1:2012 defines the Emizon service as a dual path
system and customers should note that a single path system, where the alternate
path is either not configured or not working at the point of installation may not
comply with the desired standards.
4 - EN50136-1:2012 requires that a failure of the ATS communications path is
signaled to the alarm system. The Emizon TCD is designed to signal a
communications path fault to the alarm system using relay output 2 on the TCD,
when the relay configuration is set to the default normal mode. In order to maintain
compliance, installers should ensure that the appropriately configured relay output 2
is connected to an input on the alarm system for notification of an ATS path fault.
5 - EN50136-1:2012 defines a new requirement for signaling to the alarm system
from the communicating device (Emizon TCD) where the Emizon TCD must indicate
to the alarm system if an alarm is not delivered within the performance
requirements maximum delivery time in the standard. The Emizon TCD can be
configured to use relay output 3 to indicate this condition. In order to maintain
compliance, installers should ensure that the appropriately configured relay output 3
is connected to an input on the alarm system for notification of a failure to deliver
performance event.
6 - Availability as defined in EN50136-1:2012 is calculated on per path, per ATS and
by ATSN as required. However, it is now possible for the Emizon TCD (or any SPT) to
define what caused each failure. For accurate calculations it is advisable to record all
causes of downtime such that calculations of relevant ATS downtime can be made
more accurately.
7 - When the TCD is NOT placed in the AS System housing and therefore the parallel
interface interconnect cable is not protected by this system housing special
configuration is needed to achieve tamper detection. In such case installer needs to
connect two wires within the interconnect cable, each to a parallel input. One input
should be configured as Pos-applied
and the other Pos-removed. Corresponding input alarms should be defined at the
ARC as Interconnect Tamper between Alarm system and TCD.
8 - Installer has to verify and arrange the ATS in such manner that in situations
transmission links are shared with other alarm and/or non-alarm applications this will
not prevent the ATS to meet its performance, operation and maintenance
requirements of the European Standards applicable.
9 - The installer should record in the site log where alternative facilities are provided
such that accurate availability can be determined, as it is impossibility for an ATS to
detect this situation, and the ATS will therefore treat record and define any outage of
