Additional protective contour
There may be connected the additional protective
contour to the IGLA ALARM system for providing
maximal protection to the car from being theft. It
begins to work in the case the connection with the
engine operating module through the CAN-bus has been
interrupted or hindered. This type of blocking allows the
anti-hijack and the engine stop functions to be realized
in the cars where the digital type of blocking through
the CAN-bus is unavailable.
In the case the additional protective contour is already
being used by the CONTOUR hood lock module, the
additional analog relay connection to the IGLA ALARM
system is not required.
Additional contour connection
Additional contour blocking is realized through the
normally closed contact of the relay. This type of
blocking is used in the case of an emergency in the
cars for which the digital type of blocking through the
CAN-bus is not supported. Analog blocking may be
used in any circuits breaking of which may result to
the engine stopping (even if it may result to emerging
of some errors). The blocking is implemented by the
«minus»- potential appearing at the blue wire when
the ignition or the engine is ON (the status is being
monitored through the yellow «ignition» wire).
