RS300 Passive Arm / Disarm When the RS3200 is programmed to Passively Arm, the system will arm after the ignition key is removed and all doors and the trunk or hatch are closed; you do not need to lock the doors. When you come back to your vehicle and open a door, you must insert the key into the ignition switch and turn it to "ON" during the Entry Delay (0, 15, or 30 seconds), or an alarm will be triggered. If you lock the doors, regular arming will override Passive Arming; there will be no entry delay.
