Every subsystem must pass certification in order for it to be integrated with an HMS.
This is a process similar to conformance testing that subsystems must pass in
order to receive industry certification for standards compliance. If a subsystem
has passed an industry standard protocol conformance test then there is no need
to have ESC certify the subsystem. However, since few subsystems on the market
today conform to any industry standard, there is a great unknown when attempting
to integrate a subsystem with a home control system. This is not a situation unique
to ESC. Every system integrator is faced with the same problem — How does one
know a subsystem's remote control capabilities if it is not certified to a published
standard? The answer is that each subsystem must be evaluated on its own merits.
ESC has established guidelies for the requisite command and control of subsystems
that have remote communication capabilities. The certification process is designed to evaluate
and document the capabilities of a subsystem's remote control communications
interface, typically some form of serial communications interface (e.g. RS-232).
The certification report that we generate details our findings in a way that
makes it easy for a systems integrator to compare and contrast the
various subsystems to determine the viability of a subsystem in a particular
application and the level of integration required. ESC has established
this service in an attempt to help unify the home management industry,
establish an integration database open to all for reference, and to foster an
open forum of communications between manufacturers and integrators.
The certification is typically initiated by the subsystem manufacturer in order
to gain acceptance by the home systems community. It also can be performed at
the request of homeowners, dealers, installers, builders, architects, or anyone
else with a vested interest in a subsystem's integration and use in a home
management system. Due to the simplicity of their control capabilities,
subsystems that can only be controlled by infrared (IR) remotes or a discreet
digital interface (contact or voltage input and output) do not require
certification. ESC certification has two levels: qualified and certified.
These levels are explained in detail below.
Qualification
A qualified subsystem is one that meets at least the following basic criteria
for integration:
· |
one or more industry standard communications ports, e.g. RS-232 or network,
|
· |
a suitable protocol and command set for the requisite functions,
|
· |
documentation adequate for a skilled integrator to communicate
with and control the system, and
|
· |
manufacturer willingness to cooperate in the certification process
and to provide technical support to system integrator installing
their product.
|
Qualification requires manufacturers to submit to ESC the following materials:
· |
technical documentation including design, installation,
programming, and protocol information,
|
· |
installation and user guides,
|
· |
any other documentation ESC requires to determine suitability
for integration.
|
ESC reviews all documentation and discusses the technical merits with
subcontractors and manufacturers to determine if the subsystem provides
the necessary command, control, and query capabilities. Subsystem qualification
does not guarantee certification, but provides a first-pass cut of those
subsystems that will definately not pass certification. The main purpose
behind the qualification process is the minimization of risk (i.e. time and
cost) in the certification process. Qualifed subsystems stand an excellent
chance of passing certification. The fee for subsystem qualification is
US$1,500 and usually takes about three weeks to complete (after receipt of
all documentation). Neither ESC, its representatives, nor its dealers make
any profit on this service. The manufacturer and the qualified product will be
added to the list below, and a separate page of qualification notes is also
provided on this site.
Certification
A certified subsystem is one that passes the physical integration process.
During certification, ESC prototypes interface hardware and software and
verifies the subsystem's communication capabilities and functionality against
its documentation. Further stress testing is performed using an actual Home
Management System to identify weaknesses in the communication protocols and
verify fitness of the subsystem for computer control. ESC requires a typical
complement of subsystem hardware and software for testing that is representative
of a real application. Subsystem components are normally provided by the
manufacturer or subcontractor.
Once certified, a subsystem is guaranteed to integrate with an HMS. The fee
for the certification varies with the complexity of the subsystem along with
the quality, quantity, level of detail and accuracy of available documentation.
Typically certification fees are between US$3,000 and US$8,000. Certification
of a subsystem typically take about 4 to 8 weeks (after receipt of subsystem
hardware and software). Neither ESC, its representatives, nor its dealers make
any profit on this service. The manufacturer and the certified product will be
added to the list below, and a separate page of certification notes will be
provided on this site.
Field-Testing
Whereas this is not an official phase of the certification process,
a field-tested subsystem is one that has been used in an actual installation.
Whereas certification guarantees subsystem operation with an HMS, user related
items (e.g. user-interface ease of use, subsystem suitability to real world
applications, etc.) can only be evaluated under real world conditions.
ESC's experience with a subsystem in the field, along with client acceptance,
forms the basis of a field-tested subsystem. Field notes on the subsystem will
be added as appropriate.
Certified Subsystem List
The subsystems listed below have gone through, or are in the process of going
through, the certification process. They have been certified and field-tested
unless otherwise noted. The list is dynamic and new subsystems are constantly
being added. In a future update we will be publishing the certification
reports for each of these subsystems.
