Vehicle security systems
First Claim
1. A complementary security system for installation, at least in part, in a vehicle, said complementary security system comprising:
- a control module for receiving a trigger signal indicative of an alarm condition detected by an security system, the trigger signal having a given trigger sequence for the vehicle, the trigger sequence having a predetermined minimum duration to be indicative of the alarm condition, said security system being already installed in said vehicle and having a remote Radio Frequency (RF) communication system having a first communication range for communicating a first alarm signal to a user via a first remote control device;
a communication module connected to the control module and adapted for transmitting by Radio Frequency (RF) a second alarm signal upon receipt of said trigger signal by said control module, said second alarm signal having a second communication range greater than the first communication range and having a frequency level corresponding to that used for remote control devices; and
a second remote control device for alerting the user upon receipt of said second signal, said second remote control device being located beyond the given communication range of the remote communication system of the security system.

Abstract
A complementary security system for installation, at least in part in a vehicle, has an Original Equipment Manufacturer (OEM) security system installed therein. The complementary security system for communicating an alarm condition beyond the communication range of the OEM security system. The complementary security system comprising: a control module for receiving a trigger signal being indicative of the alarm condition detected by the OEM security system; a communication module for transmitting by Radio Frequency (RF) an alert signal upon receipt of the trigger signal by the control module; and a remote transmitter for alerting a user upon receipt of the alert signal. The remote transmitter being located beyond the communication range of the OEM security system. A corresponding method is also described.

8. A method for communicating an alarm condition, said method comprising:
-
receiving a trigger signal indicative of an alarm condition detected by an original security system, the trigger signal having a given trigger sequence for the vehicle, the trigger sequence having a predetermined minimum duration to be indicative of the alarm condition, said original security system being already installed in a vehicle and having a remote Radio Frequency (RF) communication system having a first communication range for communicating a first alarm signal to a user via a first remote control device; transmitting by Radio Frequency (RF) a second alarm signal upon receipt of said trigger signal, said second alarm signal having a second communication range greater than the first communication range and having a frequency level corresponding to that used for remote control devices; receiving said second alarm signal beyond the given communication range of the remote Radio Frequency (RF) communication system of the original security system at a second remote control device; and alerting the user upon receipt of said second alarm signal. - View Dependent Claims (9, 10, 11, 12, 13)
