This Viper Keyless Entry system offers features like Ignition Controlled Door Locks and Domelight Supervision, two 4-button remotes and parking light flash confirmation. System comes with 2 auxiliary outputs for optional remote control conveniences.
Overview: The Viper 412V keyless entry system lets you add remote operation to your vehicle’s existing power door locks. It features built-in door lock relays with ignition control, dome light supervision, parking light confirmation flash, as well as 2 auxiliary outputs for adding optional remote operated conveniences.
Door Locks: The 412V’s built-in lock and unlock relays can integrate into most any vehicle’s door lock system (additional parts may be required for some vehicles). Door locks can be activated with one of the included 4-button remotes and include other operational configurations such as:
- Passive Locking: The Passive Locking feature, if activated, will automatically lock the doors 30 seconds after the ignition has been turned off. This feature requires that the Failsafe Starter Kill feature be turned on first to access Passive Locking. If the system is unlocked with the remote, it will re-activate the door locks in 30 seconds if the ignition isn’t turned on during that time.
- Progressive Door Unlocking (Driver’s Priority Unlocking): The 412V can be configured to allow the driver’s door to be unlocked with the first push of the unlock button and unlock the rest of the doors with a second push within 15 seconds. Additional parts will be required to wire in this feature for most vehicles.
- Comfort Closure: This feature is designed to integrate with vehicles that can close the power windows or a sunroof by holding the key in the driver’s door lock position. If this feature is programmed on, the door lock output will activate the Comfort Close output for 20 seconds. If during that time the system is unlocked, the Comfort Close output will stop.
- Double Pulse Unlock: Some vehicles require two pulses on a single wire to unlock the doors. When this feature is activated, the Blue/Black unlock wire will output two negative pulses instead of one.
- Double Pulse Lock: Similar to the Double Pulse Unlock, this provides a two pulse door lock output for certain vehicles equipped with a factory “deadbolt” lock system.
- Door Lock Pulse Duration: Some European vehicles use a vacuum pump locking system that requires longer lock and unlock pulses. The 412V’s default setting is 0.8 seconds, but can be changed to 3.5 seconds or 0.4 seconds. This last option is used by some vehicles to prevent the windows from moving during locking.
- Ignition-Controlled Door Lock/Unlock: This feature allows the door locks to activate 3 seconds after the ignition is turned on and unlock when turned off.
Parking lights: The Viper keyless entry system includes a high-current parking light output, both positive and negative, to flash the parking lights while locking and unlocking. An internal jumper allows the polarity to be switched for either type parking light system.
Dome Light Supervision: The 412V can activate the dome light for 30 seconds after being unlocked with the remote control, allowing for better visibility at night. The provided Dome Light Output wire gets tied into the vehicle’s dome light wire while the Dome Light Input wire gets tied to either +12 V or ground, depending on the polarity of the factory dome light system.
Ground When Armed Output: The Ground When Armed Output wire provides a 500 mA ground as long as the system is armed/locked. This is used for automatically activating optional add-on features such as a Failsafe Starter Kill relay or a window roll-up module.
Auxiliary Outputs: Two Auxiliary Outputs are provided on the 412V. Channel 2 supplies a 200 mA ground output when the Aux button on the remote is pushed for more than 1.5 seconds and will continue outputting as long as the button is held. This is most commonly used to operate a trunk-release or other relay-driven functions. When Channel 3 is programmed for use, it will output a 200 mA ground output as long as both lock and unlock buttons are pressed simultaneously, typically used for activating an add-on remote starter or window roll-up module.
Horn Honk: The Horn Honk Output wire will provide a 200 mA ground output to honk the vehicle horn once when locking and twice when unlocking the doors. It will also output pulses for 30 seconds if Panic Mode is activated. Vehicles with a positive horn system will require an additional relay (sold separately) to provide +12 V to the horn wire. Note: The horn will only honk when the system is in audible mode, by either pressing the Lock button on the remote a second time within 5 seconds or by pressing the Aux button prior to pressing Lock or Unlock.
Valet Button: A push-button Valet switch is included, which allows access to the programmable features such as Passive Arming and Door Lock Pulses. It also serves as an emergency override if a starter kill relay is installed and the Failsafe Starter Kill feature is activated. If the keychain remote is lost, the system can be “disarmed” and the starter kill relay released, by turning the ignition key On and pressing the Valet button once within 10 seconds. This button is also used to put the system into Valet mode which prevents it from automatically locking/arming and activating the Failsafe Starter Kill feature while having the vehicle serviced or left with a parking attendant. The Valet button should be mounted in a hidden location, but easily accessible by the driver. It will require drilling a 9/32″ hole and needs approximately 1″ of clearance behind it.
LED Status Indicator: A dash-mountable blue LED is provided to display the status of the keyless entry system at any time, as well as provide visual confirmation while programming optional features. Multiple LEDs can be wired together in a series configuration, but care should be taken to never wire blue LEDs with red ones. The LED indicator requires drilling a 9/32″ hole and approximately 1″ of clearance behind it.
