Mongoose MAP77 Installation Manual page 4

IMPORTANT!
For some vehicles, the MAP77 VSS uses the orange wire to monitor the
additional analogue status signals. Check the installation diagram for particular
vehicles. In these vehicles the orange wire CANNOT be connected to ignition
circuit. It MUST be connected according to installation diagram.
Dual function line/programmable lines
Some inputs/outputs are configureable and change their function depending
on VSS configuration.
The orange wire can be analogue ignition signal or trunk release actuator
positive input or central door locking analogue status positive signal input.
The brown wire can act as pager ground output (active when alarming),
pulsed pager output (pulsed output when alarming), as CAN bus reverse gear
signal output (for park sensor modules)as additional immobilisation NC relay
output or as central door locking analogue status negative signal input.
Rear 3-pole connector function is configureable. It can work as additional
sensor alarm input, additional sensor prealarm input, RF receiver module
connector and as an output of windows roll-up signal. Rear 3 pole connector
input (blue wire in connector) can act as alarm triggering input, as prealarm
input or as communication line to RF module. Rear 3 pole connector ground
signal (black wire) can be switched on when armed, can be used as windows
roll-up analogue output or as a constant ground for RF module.
Always check the installation diagram for particular vehicle!
CAN bus ignition signal or CAN bus bonnet signal inhibit
In spite of the efforts put on measurement of the vehicles, sometimes, on very
rare model variants of vehicles, CAN bus signals are different than on popular
models and thus lead to improper operation of VSS. In order to preserve
operation of VSS, there is a possibility to inhibit (block) reading of ignition signal
and bonnet switch signal from CAN bus.
CAN Ignition/accessory position signal blocking is usefull when false alarms from
IGN are noted in VSS memory or the VSS cannot be armed due to constant
false ignition/accessory signal.
Bonnet signal inhibit can be usefull when the vehicle not equipped with bonnet
switch sends CAN information as the bonnet was opened, chirping everytime
the VSS is armed.
OEM alarm detection
If car is equipped with the OEM security system, start of OEM alarm cycle can
trigger alarming in Mongoose MAP77 VSS. That feature allows MAP77 to protect
car using OEM motion detector and OEM towing detector. IMPORTANT: In case
the OEM motion detector is ultrasonic (e.g. VW Passat, Seat Ibiza) it can
interfere with MAP77 ultrasonic motion detector (false alarms). In such case, do
not connect ultrasonic transmitter and receiver to MAP77 and enable OEM
alarm detection.
