Meta M99T2/M36T2

[s6otty]

Just about sorted the wiring! It's sitting on the bench working. (Cheers Brucie!)

Does this unit have an Auxiliary output (Im guessing not as it only has 1 Button.)

The central locking is Positive Pulse Lock and Unlock, is the easiest solution to use 2x5 Pin relays to swap the polarity for Lock/Unlock on the solenoids?

The relay on the other thread is what you need

[s6otty]

So if I bin the standard locking/alarm unit and identify the locking wires - job done?!?!?

All I can do at the moment is to power 2 wires from one of the solenoids and this works them both, swapping polarity for lock/unlock.

I assume the button in the centre knob just gives a positive pulse each time you press it?

You have it pretty much worked out.

If you have an original grey "Italamec" relay it has the wiring diagram on the side. If you don't there are 6 connections on universal CDL relays:

Earth (usually the pin at the end on its own)
Permanent live
Motor 1
Motor 2
Pulse lock
Pulse unlock

[s6otty]

Ordered, thanks for that.

I assume motor 1/motor 2 are the 2 wires to one motor, paralled to the other?

How does the button in the middle differenciate between lock and unlock if it is a single pulse?

Yes, correct with motor wiring.

There are two pulse connections on the relay, one for lock, one for unlock. The button wire is connected to the lock one, it doesn't need an unlock one, it unlocks mechanically via the cables, if that makes sense?

[s6otty]

Yep, Just use the button to lock, open the door to unlock! :-)

I was curious, thought I read somewhere press once to lock, press again to unlock, but I have been doing far to much reading lately!

Thanks again.

Do you know how the courtesy light switches unlock the solenoids? They bring the light on with a -ve, but the locking requires a +ve!

My old CDL/Alarm unit - for the bin!

[Ribol]

Are you not doing a new install?

Wire the Meta to -ve pulse and take the door opening pulse from the door switches as TVR did.

[s6otty]

The Meta was with the car in a box! Infact, lots of the car was in boxes!

I don't have the wiring diagram from the Meta, but having it on the bench testing, it appears to be +ve, and I don't know how to change it, but no doubt can find out!

I've yet to figure the actual solenoid wiring apart from flicking the power around to lock unlock, one has 4 wires, I need to trace them out.

Didn't realise they were -ve locking

You probably have the light blue/white and red/white wires going to a live supply?

Connecting them to earth instead of live will give you a -ve pulse instead of +ve.

[s6otty]

I have just tested them on the bench and they pulse live on arm disarm, only the live/ ground is connected on the alarm, am I reading my results incorrectly?

What are these wires connected to?

[s6otty]

Nothing at the moment, just used a test lamp to see what did what when it was powered up and armed/disarmed.

I know on alarms you can program them to be either +ve or -ve, and on others if you take a certain wire to +ve or -ve it changes the locking polarity.

I hoping the relay will replace the existing module, including getting the centre button working. Then the Meta can be fitted.

[Ribol]

With the alarm wired up and arming/disarming try this:

Connect light blue/white and red/white together and then earth them.

The red/yellow should give you a -ve pulse to unlock
The light blue/yellow should give you a -ve pulse to lock

[s6otty]

Aha, the yell/blue + yell/red have been taken to live, which makes you correct sir, move this to -ve and it should lock -ve, result! Thanks. Wonder why they had it positive, since the Chim is -ve locking! If the postman hurry's up with my relay I can try to sort the rest of it!

You don't move those to -ve, you follow my previous post.

[s6otty]

Because of the internal relays. Understood.

Thanks
