Radio Keys
Arming the System
The System will automatically arm the
double immobilisation 60 seconds after
the ignition is switched OFF and the
driver's door is opened. If the doors are
not opened the delay is extended to 255
seconds after the ignition is switched OFF.
l The LED will flash.
It will not now be possible to start the
engine, but in this instance the doors will
not lock and the windows etc. will not
close. The door trigger circuits and interior
sensor do not arm.
DRIVING THE VEHICLE
To start the engine, ensure the ignition is
switched OFF then disarm the immobiliser
by pressing button ‘A’ on the radio key and
then switch ON the engine within 255
seconds.
To fully arm the system after passive
immobilisation, switch OFF the passive
arming by pressing button ‘A’ on the radio
key, then re-arm the system (as described
in ‘Arming the System’).
The emergency override touch key can be
used to disarm/ de-immobilise your Cobra
7928/26/HF Alarm System in the event of
lost or damaged radio keys. If your car is
locked use your door key to enter the car
and touch the Emergency Override Touch
Key on the contacts of the touch receptacle
- this will disarm and de-immobilise the
security system. If the system was fully
‘armed' the siren will sound until
disarming has taken place. The car can
then be started in the normal way.
l Up to four Emergency Override Touch
Keys can be programmed into each
Cobra 7928/26/HF Alarm System.
The radio keys for your Cobra 7928/26/HF
Alarm System have a ‘protected self-
learning' feature which allows up to four
Radio Keys to be programmed into your
system by using its unique PIN code in
conjunction with the electronic touch keys.
All existing radio keys and touch keys
must be re-programmed at the same time
as any additional or replacement keys are
being introduced to the system. Your
Cobra Dealer will be able to carry out this
procedure for you.
Radio Key - pressing the operating button
‘A' will arm the system, indicated by:-
1. Two flashes of the vehicle's hazard
lights.
2. Continuous flashing of the LED
warning light.
3. Simultaneous locking of all doors.
l Immediately the alarm unit is switched
ON (‘armed') the vehicle is
immobilised.
After switching ON (‘armed') a period of
approximately 45 seconds will elapse
before the system is fully active. (This is a
‘setting-up' and ‘test period').
When the alarm is fully active it will be
triggered by:-
1. Opening a door, boot or bonnet (Direct
Contact Switches).
2. Movement within the vehicle
(Ultrasonic).
When triggered the Electronic Siren will
sound at 118dB and the hazard lights will
