The FT-RPS TOUCH is compatible with all AlarmIt and MaxIt Systems. It contains three super blue LEDs that flash while the system is armed. The system will also respond to a double touch that pages your 2 Way remote and lets you know someone is trying to reach you at your vehicle. The FT-RPS TOUCH takes innovation further with a touch unlock feature. Program a 4 digit code that lets you disarm your system without remote and key. Hold your finger on the sensor to also rearm your system
