RE: [DML] Re:Door Lock solenoids/Car Alarm

[Peter Lucas <lucas@xxxx>]

All that is needed from an alarm system in order to operate the 
Delorean central door locks is the ability to provide a momentary 
ground on the appropriate side of the door lock circuit to lock or 
unlock the doors. This ground signal will be sensed by the existing 
door lock module (or, I assume, Lockzilla if you have upgraded), 
which will then activate the appropriate solenoids. The module will 
bear the current, not the alarm or its relay, just as the door lock 
switches do not do so in the stock configuration.

Most modern alarms can be programmed to provide either a +12 pulse or 
a ground pulse for this purpose. The correct choice for the D is 
"ground". I have been very happy with the Phoenix 2 by Avital.
