SR75H REMOTE CONTROL CAR ALARM SYSTEM
10
RED WIRE-POWER SUPPLY AND CURRENT SENSING
The SR75H is triggered by the operation of the interior light or any
electrical circuit on the vehicle. This is detected by the RED power
supply wire. The trigger sensitivity will vary from vehicle to vehicle
depending on size and age of the car battery and the rating of the
interior light bulb. As a general principle the sensitivity will increase
the further from the battery the main supply connection is made. For
optimal operation the interior light bulb should be rated at 10 watts
minimum.
To determine the best connection point a simple test
procedure should be followed as below.
1)
Temporarily connect the RED wire to the battery positive
terminal.
2)
Close all doors, boot and bonnet then arm the alarm with the
remote control.
3)
Wait at least 20 seconds then open any door. If the alarm
triggers you can make the connection to the battery positive
(+) terminal permanent.
4)
If the alarm fails to trigger during step 3 disconnect from the
battery and route the RED alarm wire to the fuse box and
repeat the test using permanent live at the fuse box, following
steps 2 and 3 as above.
5)
When
the
test
is
successful
make
your
connection
permanent.
ORANGE/WHITE WIRE-CENTRAL LOCKING CONTROL
This is only applicable for vehicles that have central locking as a
standard
feature.
Do
not
attempt
to
directly
connect
ORANGE/WHITE wire to any part of the vehicle central locking
system. The ORANGE/WHITE wire must only be connected to the
optional Sparkrite SR911 Central Locking interface. This will allow
the vehicle doors to be locked and unlocked by the alarm remote
control. If this feature is not used, insulate the wire and secure it in
a safe position.
