I'm currently installing a central locking system by Hawk Alarms. The control unit of the CDL system has one brown and one white wire coming from it, which the company say can connect to an alarm system so that they operate together. ie a lock and unlock wire.
I was hoping to connect these to the Land Rover 10AS box (mines a 1996 Defender) as it has lock and unlock pins.
I've emailed the Hawk company, but their reply was very brief and just said their white and brown wires only worked with their alarm. No explanation. Admittedly, I'm no electrician. So, can't understand why the CDL can't be triggered by another alarm system.
Saint.V8 here on LZ wondered this:
The system uses a negative pulse for lock and unlock on the brown and white wires (not sure which one is which - but it is in the manual) I believe the 10AS issues a positive pulse (you will have to check) but with a couple of relays (one for the lock signal and one for the unlock signal) you can convert the pulse round.
Can any of you electrical engineers tell me if it's do-able, or am I wasting my time trying to find a solution.
