power locks relay

howie ll wrote: Actually, use a dedicated lock timer relay from Spall, MES (the older blue is best). Also only one master is needed (5 wire) for driver door . You need a timer because when the master actuator goes back to rest the NEG going switched wire STAYS NEG. If you're just using 2 wire motors then you won't need a relay, use a Spall window switch effectively a 2 pole changeover momentary centre off switch, readily available from Mouser etc.

If i just go with a 2 pole switch, how am i gonna wire it to my alarm to unlock and lock from the remote?Aron Migz

With a 2 pole switch, must be momentary with a centre off, wire it follow the diagram that Mr. Idiot posted:- Use two X 5 pin relays. NEG to switch then one side to relay 85. 87a to ground. 30 and 86 fused, 12V+ constant, 15 amps for two actuators, 25 for four. 30 Green. Other switch output to 85. 87a to ground. 30 and 86 shared with relay above. 30 to blue.

Thanks alot. Im gonna give that a tryAron Migz

This is the first time you've you've mentioned an alarm, if you fail to tell us how can we teach you? Lock and unlock (NEG) to 85 on either relay, you'll probably need to turn some of these lock and unlock wires around so don't solder until everything works. I really can't help any more unless you tell us what kind of alarm, make and model and whether there are two or six lock/unlock wires coming from the alarm, you'll also now need to diode the relays, 1N4004 across 86 and 85, band to 86.

Okay well its a presitge alarm. Its a 3 wire neg. pulsed door lock blue for unlock,green lock, blue/green secondary unlock. The door lock actuators 2 wires. Green and blue. Aron Migz

I really love the way I can become invisible at will.
