30: neons
87: alarm trigger
85: 12v fused supply
86: Ground

I think you have your relay wired wrong. if you wire 85 to ground and 86 to fused 12 volt then the relay would turn on right then and stay on. Wire 85 to the alarm trigger and then 86 and 30 to the fused 12 volts. Then run 87 to the positive wire on the noens. Ground the neons to a constant ground and that should do it. If you press the button on the remote the lights will come on but if it is not a latching channel then they will only stay on momenterally or as long as you hold the button depending on your alarm and what channel you have them hooked to. Let me know if that works. You can always make a channel a latching channel too. peace.

hi...
the output wire from the alarm module gives an output of (-)300mA...ive tried to connect the relay as told mby the second answer but still did not work...do i have to use a 5 pin spdt relay or is the 4 pin without pin 87a fine?

I believe that may be your issue, you will need to wire the relay up with:
86 and 30: 12+ Fused
85: 12- output from alarm
87: to neon

Try that and let us know... If it doesn't work, can you see if you can hear the relay "clicking"? That would help us in assisting you.

This is a good one.

You are sure that the alarm accessory wire is putting out 12-? Have you used a DMM to test this? Getting a 5-pin relay won't help cause you don't need the NC circuit. I'm inclined to think that the relay is bad but you say that you have tested it?

try this: a) Connect the fused 12v+ to Pin #86, then use a scrap piece of wire and connect it to Pin #85 and touch the other end to ground. You should hear the relay "click", if not then the relay is bad (unless it's a silent one).

b)if you do hear a click then try connecting your arm wire to the Pin #85 and arm the alarm. If you don't hear a click then there are issues with your alarm wire. They could be a setup problem, a momentary latching problem, a programming problem or that the wire is not giving 12- when activated.

Let us know what happens and we'll help you through this!
