Description
The system consists of a 5"L X 3.25"W X1.2"H board on which the entire electronics is mounted. A separate harness for the wires leading out to the keypad is provided. Four relays controls the AC and Stereo power as well as disables the Ignition and turns on the Hooter in case of wrong code entry. The code entry system is also elegantly designed and easy to use. The code entry is designed for complete ease of use for any user who can enter the code or change the code without any confusion. Also, if the password is forgotten or leaked to someone, the code can be easily changed using a second MASTER password which can be up to 10 digits long and which resets all the user passwords for AC, Stereo and Alarm passwords to zeros.
