Hi FG.
If it's a Frontier alarm module, here are the instructions (link halfway through the thread):

If it's got a piezo in the caseback, then odds on it's an alarm module. I only know of one LED alarm module.........the Frontier. If it works, and you don't want it, you could always swap it into the Lanco.
